Congratulations! With buying a DYNACORD CL-SERIES power amplifier you have chosen an appli-
ance that employs most advanced technology.
CL-Series power amps combine outstanding audio performance, highest reliability and operational
safety.
The audio performance of CL power amps are simply extraordinary. Optimised power supply units em-
ploying low-leakage toroidal transformers and the consistent use of Class-H technology provide exten-
sive headroom far above the stated nominal output. At the same time this contributes to a reduction in
weight and power dissipation.
The CL1200/1600/2000 is designed in Class-H technology, i.e. the power amp provides extremely
fast, signal-dependent operating voltage switching, which results in doubling the regular supply voltage
when needed. Compared to Class-AB power amps, Class-H power amps generate by far less power
dissipation at identical output. Consequently, reduced leakage power or dissipation is synonymous to
less waste heat – energy is used more efficiently. As a result, installing Class-H power amps within rack
shelf systems is possible with less space between appliances. In addition to that and despite offering
identical output, power consumption is a lot less than in Class-AB operation.
DYNACORD CL-SERIES power amps have been designed to fulfil even the most demanding
requirements of touring applications. CL-Series amps are protected against thermal and electrical
overload, short circuit and the occurrence of HF/DC at the outputs. Back-EMF-Protection eliminates
the risk of the output transistors being damaged by electrical energy back-feed. The power outputs are
switched via relay with a time delay during soft-start. An inrush current limiter prevents mains fuses from
blowing.
Mechanical construction and workmanship also comply with the highest precision manufacturing
standards. The rigid sheet steel chassis even resists the most wearing tour operation. Two three-speed
high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running
noise. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks.
The electronically balanced inputs are carried out via XLR-type connectors. Direct-Outs for through
connecting the audio signal are also provided via XLRM-type connectors. Input Routing allows selecting
DUAL (stereo) or PARALLEL (monaural) operation mode. By means of the separate BRIDGED OUT-
connector and a Bridged Mode-switch, switching to „Mono Bridged“ operation is truly uncomplicated
as well. The recessed mounted dB-scaled level controls ensure reliable protection against mechanical
damage. These particularly precise, secure to operate detent-potentiometers are located on the
front panel. CL-Series power amps provide the opportunity for retrofitting an internal analogue signal
processor board with x-over and filter functions.
The easily readable LED display provides a quick overview of the power amp’s current operational
status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely
durable SPEAKON-type connectors. Also located on the rear panel is a Ground-lift switch, which helps
eliminating ground-noise loops by separating the power amp’s enclosure from the circuit ground. In
normal operation, all CL-Series power amps are capable of driving loads as low as 2ohms. In Mono-
Bridged mode the allowable minimum load is 4ohms.
This owner’s manual outlines and explains several other features of your CL-Series power amplifier.
Please, make sure to carefully read all of it and mind the instructions.

UNPACKING & WARRANTY
Carefully open the packaging and take out the power amplifier. Next to the power amplifier itself, the
package also includes this owner’s manual, a mains cord and the warranty certificate. Keep the original
invoice, which states the purchase/delivery date together with the warranty certificate at a safe place.
INSTALLATION NOTES
Generally, installing or mounting power amps should be carried out in a way that guarantees continu-
ously unopposed front-to-rear air circulation. Installation of appliances with opposite air circulation within
one cabinet or closed rack shelf system is not recommended. When including an appliance in a closed
cabinet or rack shelf system make sure to provide sufficient ventilation. Leave a gap of at least 60mm
x 330mm (up to the cabinet’s top ventilation louvers) for air circulation between the rear of the power
amplifier and the cabinet’s/rack’s rear inner wall. Make sure to leave at least 100mm of space above the
cabinet or rack shelf system. Since temperatures inside of the cabinet or rack shelf system can easily
rise up to 40°C during operation, bearing in mind the maximally allowable environmental temperature
during operation for all other appliances installed in the same rack shelf system is mandatory (also refer
to “MAINS OPERATION AND RESULTING TEMPERATURE”).
Caution: For trouble-free operation exceeding the maximally allowable environmental tem-
perature of +40°C is not permissible.
The use of installation rails or optionally available “rear-rack-mount” rails is strongly recommended when
installing the appliance in a rack shelf system or cabinet to prevent the front panel from bending.
The power amplifier has to be protected against: dripping or splashing water, direct sunlight, high tem-
peratures or direct influence of heat sources, high humidity, extensive dust and vibrations.
Condensation on internal parts may occur when transporting the power amplifier from a cold into a
warmer environment. In that case operation is only permissible after the appliance has gained the
new temperature (after approximately one hour). If foreign objects or liquids have entered the power
amplifier’s enclosure make sure to instantly separate the appliance from the mains power and contact
an authorised service centre for inspection before continuing operation.
5
Use the POWER switch, located on the front panel’s, right side to switch the appliance’s power on. The
soft-start function limits against current inrush peaks on the mains, which in addition prevents the mains
line protection switch from activating during power-on. The loudspeaker outputs are activated via relay
switching with a delay of approximately 2 seconds to efficiently attenuate eventual power-on noise. The
PROTECT LED lights during the delay time and the fans run at maximum speed. This is normal, con-
firming the correct operation of the protection circuitry.
POWER-indicator not lighting are: the appliance is not connected to the mains
or the primary fuse is defective.
The PROTECT LED indicating that one of the internal protection circuits
against thermal overload, short-circuit, Back-EMF, RF-occurrence at the output,
etc., has been activated. The output relays interrupt the connected loads from
the power amps while input signals are interrupted as well, preventing the connected
loudspeaker systems and the power amplifiers themselves from being damaged.
Whatever caused the fault – e.g. a short-circuited speaker cable – needs to be reme-
died. In case of thermal overload you have to wait until the power amplifier automati-
cally regains normal operation.
The SIGNAL LED lights as soon as an audio signal of approximately 30dB below full
modulation is present at the output. The LED is dimmed when speaker cables are
hort-circuited or a protection circuit has been activated.
The 0dB LED lights whenever the power amplifier is driven at its maximum. Higher
nput voltage does not result in higher peak output voltage. In addition, the 0dB
ndicator comes in handy when adjusting external limiters.
This indicator lights as soon as the integrated dynamic audio signal limiter is
activated and the power amplifier is driven at the clipping limit or generally at its
maximum capacity. Short-term blinking is not a problem, because the internal limiter
controlls input levels of up to +21dBu down to a THD of approximately 1%. If, on the
other hand, this LED lights constantly, reducing the volume is recommended to
prevent the loudspeaker systems connected from being damaged by probable
overload.
Detent potentiometers scaled in dB (steps of 1dB) for
adjusting the power amp’s overall volume. To prevent
distortion in mixing consoles connected to your CL-Series
amp, setting these controls to a value between 0dB and -6dB
is generally recommended. The dB-scale provides direct
indication of the control attenuation applied to the fixed
internal amplification.
6
INPUT A / INPUT B
The inputs INPUT A & INPUT B of the CL series are electronically
balanced. The voltage gain of all models is set to 32 dB (constant
gain). This results however in different input sensitivities for the
different models (see table), but the level adjustment of active
crossovers or signal processors in multi-way systems is much
easier. Power amplifiers with different output power can be
changed without consideration, the crossovers have not to be
adjusted due to the constant amplification of the whole unit line.
If external voltage limiters are used, they should be set to the
used power class with consideration of the connected speaker
systems. The XLR-type connectors OUTPUT A & OUTPUT B
are prepared for „through-connecting“ input signals to additional
external power amps. The input signal is directly routed to these
output connectors. There are no repeaters or other electronic
components within that signal path. Accordingly, input and output
connectors of the corresponding channel are interconnected in
parallel, offering permanent electrical connection, without regard
to the setting of the Power-ON switch.
CL800 +1.15dBu / 0.88V
CL1200 +3.2dBu / 1.12V
CL1600 +4.7dBu / 1.33V
CL2000 +5.5dBu / 1.46V
Although having XLR-type output connectors, some mixing console models provide unbalanced
output connection only. When using mixers with unbalanced outputs, bridging PIN1 and PIN3
of the power amp’s input connectors or leaving PIN3 of the cable’s plugs unconnected is
necessary. Otherwise, when feeding in unbalanced audio signals via PIN3 (b, -, „cold“) and PIN2
(a, +, „hot“), strange humming and RF-interference may occur, which very likely will damage the
power amplifier and/or the connected speaker cabinets.
NF-CONNECTION CORDS
Choosing high-quality balanced cables (two conductors for the audio signal plus seperate shielding
mesh) with XLR-type connectors are recommended for LF-signal connection. Although connecting un-
balanced cables to the power amplifier inputs is possible as well, using balanced cables is always pref-
erable. A great number of today’s audio appliances employ balanced outputs. With balanced cabling,
the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction of ex-
ternal interference – mostly noise and hum.
type connector pin-assignment
XLR (male)
XLR (female)
PARALLEL
The input connectors of channel A and channel B are electrically connected in parallel
when the selector switch is set to PARALLEL. However, individually controlling the
volume of both channels is still possible via the corresponding level controls A and B.
DUAL
If the selector switch is set to DUAL, the audio signals of channels A and B are
independently amplified.
7
Power amp output connection for the two channels A
(left) and B (right) is provided via SPEAKON-type output
connectors.
A plastic cover to prevent inadvertent erroneous
connection protects the BRIDGED OUT connector. Make
sure to remove the cover only when actually operating the
power amplifier in Bridged-Mode.
CAUTION!
Pins 2+/2- of the CHANNEL A SPEAKON output, which
normally are not in use, are also connected to output B to
ensure comfortable connection of 2-way speaker cabinets
(e.g in Bi-Amping Mode) when using 4-wire Speakon
cables.
To prevent short-circuit and/or to protect your speaker systems from being damaged when connecting
the cabinets, please make sure to mind the Low- and High channels’ specific pin-assignments!
If, for example, the subwoofer audio signal is used to feed a tweeter, it is more than likely that this will
instantly destroy the HF-driver’s coil.
WARNING:
The speaker output terminals are marked with a symbol “
”, which signifies that these
terminals are hazardous live and present a risk of electric shock to the user.
BRIDGED MODE
With the BRIDGED-MODE switch being engaged, using the channel A input
for audio signal feed is mandatory, since input B provides no function. While
the amplifier of channel A operates as usual, the audio signal is internally
inverted and routed to the amplifier of channel B. Both amps – A and B – now
work in push-pull operation to provide doubled output voltage at the
BRIDGED-OUT connector.
The regular output voltage of each amplifier channel A / B is still present at the corresponding output
connector CHANNEL A or CHANNEL B. However, using these signals is not recommendable because
of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms
connected is not allowable.
CAUTION: Extremely high voltages might be present at the BRIDGED OUT connector during
Bridged-Mode operation. The connected loudspeaker systems have to be capable of handling
such high voltages. Please make sure that power handling specifications as stated in the docu-
mentation supplied with your speaker systems match the specifications of the power amplifier.
GROUND-LIFT SWITCH
The ground-lift switch allows eliminating noise loops. If the power amplifier is
operated together with other equipment in a 19“ rack-shelf, setting the switch
to its GROUNDED position is recommended. If the power amplifier is operated
together with appliances with differing ground potentials, set the switch to its
UNGROUNDED position.
MAINS INPUT
Under normal circumstances, the mains fuse only blows in case of fault.
Replacing the fuse is only permissible when using a new fuse of the same
type with identical amperage, voltage and blow characteristics. If the mains
fuse blows more often, please contact an authorized service centre.
The high-performance mains cord supplied with your power amplifier complies
to applicable safety regulations, plus that its diameter corresponds to the power
amp’s power output capacity. Make sure to use the supplied mains cord for connecting the power amp
to the mains. Using mains cords with smaller diameters results in higher leakage and consequently re-
duced maximum power output capacity.
At 100V and 120V units the mains fuse is installed internally. This is fore safety reasons. In case of a
blown mains fuse please contact a qualified service personnel for servicing.

MAINS OPERATION & RESULTING TEMPERATURE
The following tables allow determining power supply and cabling requirements.
The power drawn from the mains network is converted into output power to feed the connected
loudspeaker systems and into heat. The difference between power consumption and dispensed power
is called power dissipation (Pd). The amount of heat resulting from power dissipation might remain
inside of a rack-shelf and needs to be diverted using appropriate measures. The following table is
meant as auxiliary means for calculating temperatures inside of a rack-shelf system/cabinet and the
ventilation efforts necessary.
The column „Pd“ lists the leakage power in relation to different operational states. The column „BTU/hr“
lists the dispensed heat amount per hour.
