Safety precautions
Speaker system damage and protection of human beings
Power amps provide extremely high power output that might be dangerous for human beings
as well as for the connected speaker systems. High output voltages can damage or even
destroy the connected speaker systems, especially, when the amplifier is operated in bridged
mode. Prior to connecting any loudspeakers, make sure to check the speaker system’s
specifications for continuous and peak power handling capacities. Even if amplification has
been reduced through lowering the input level controls on the amplifier’s front panel, it is still
possible to achieve full power output with a sufficiently high input signal.
Danger!
Danger at the loudspeaker/power outputs
Power amplifiers are capable of producing dangerously high voltage output that is present at
the output connectors.
To protect yourself from electric shock, do not touch any blank speaker cables during
operation of the power amp.
Danger!
The terminals marked with a lightning bolt are hazardous live and the external wiring
connected to these terminals requires installation by an instructed person or the use of readymade leads of cords.
Danger!
In case of using the amplifier with speakers including a primary tapped transformer, it is
possible that during operation shock hazard voltages may be present at the taps of the
transformer.
Therefore, the taps have to be insulated sufficiently in accordance with applicable safety
regulations.

Installation
5.1
Operating voltage
The power amplifier receives its power supply via the MAINS IN connector. Only the provided
power cord may be used. During installation, always separate the power amplifier from the
mains. Connect the power amplifier only to a mains network, which corresponds to the
requirements indicated on the type plate.
5.2
Power
The L Series power button is located on the front of the amplifier panel. The C Series power
switch is located on the rear of the amplifier panel.
5.2.1
L Series
The Power button on the front panel separates the power amp from the mains. Pressing the
Power button turns on the power amp. A soft start circuit compensates mains inrush current
peaks and thus prevents triggering AC mains fuse when switching on the amplifier. Speaker
system switch-on is delayed by approximately two seconds via output relays, effectively
suppressing any possible power-on noise, which otherwise might be heard through the
loudspeakers.
Figure 5.1: Power button on the front panel (L Series)
5.2.2
C Series
The Power switch on the rear panel separates the power amp from the mains. Turning the
mains switch to ON starts booting up the power amp. A soft start circuit compensates mains
inrush current peaks and thus prevents the automatic cutout of the mains from reacting when
switching on the power amplifier. Speaker system switch-on is delayed by approximately two
seconds via output relays, effectively suppressing any possible power-on noise, which
otherwise might be heard through the loudspeakers. PROTECT-LED lights up and fans are at
high speed during this delay. This indicates all protections are working fine.

Mounting
L Series and C Series amplifiers have been designed for installation in a conventional 19-inch
rack case. Attach the power amp with its frontal rack mount ears using four screws and
washers as shown in the illustration.
Additionally securing the amplifier at the rear becomes necessary, if the rack case in which the
power amplifier has been installed will be transported. Failure to do so may result in damage
to the power amplifier as well as to the rack case. Attach the power amp as shown in the
illustration using four case nuts and screws. Brackets for securing the power amplifier are
available as accessories.
Figure 5.3: Mounting powered an amplifier in a rack, front (left) and rear (right) showing optional RMK-15
5.4
Ventilation
As with all Dynacord power amps with fan cooling, the airflow direction is front-to-rear,
obviously because there is more cold air outside of the rack case than inside. The power
amplifier remains cooler and dissipating the developing waste heat in a specific direction gets
easier. In general, setting up or mounting the power amplifier has to be done in a way that
fresh air can enter unhindered at the front and exhausted air can exit at the rear. When
installing the power amp in a case or rack system, attention should be paid to these details to
provide sufficient ventilation. Allow for an air duct of at least 60 mm x 330 mm between the
rear panel of the power amplifier and the inner wall of the cabinet/rack case. Make sure that
the duct reaches up to the cabinets or the rack case’s top ventilation louvers. Leave room of at
least 100 mm above the cabinet/rack case for ventilation. Since temperatures inside of the
cabinet/rack case can easily rise up to 40 °C during operation of the power amp, it is
mandatory to bear in mind the maximum allowable ambient temperature for all other
appliances installed in the same cabinet/rack case.

Caution!
!
Blocking/closing the power amp's ventilation louvers is not permissible. Without sufficient
cooling/ventilation, the power amplifier may automatically enter protect mode.
Keep ventilation louvers free from dust to ensure unhindered airflow.
Notice!
Do not use the power amplifier near heat sources, like heater blowers, stoves, or any other
heat radiating devices.
Notice!
Do not use Dynacord power amplifiers in an environment where temperatures are below 0°C
or exceed +40°C.
For fixed amplifier installations in a device control room that incorporate a central air-cooling
system or air conditioners, calculating the maximum heat emission may be necessary.

GPI:
The GPI is used to change between two internal device presets. If the GPI 1 or GPI 2 is set to
GND potential, the preset is switched from the original selected preset to the preset set for
GPI 1 or GPI 2.
GPO:
The GPO is designed as a potential-free changeover switch (relay).
If power is on, GPO pin 3 and GPO pin 1 are shorted.
If the amplifier is turned off or a fault condition appears, GPO pin 3 and GPO pin 2 are
shorted.

Cabling with two Speakon-type connectors in Normal mode
The first possibility in Normal mode is to use the two Speakon-type connectors, whereas
speakers have to be connected to pins 1+ and 1– of the sockets. The correct connection is
also indicated at the amplifiers rear panel.
Figure 6.1: Normal mode
Bi-Amp cabling in Normal mode with Speakon-type connector
The second possibility for connecting the speakers when the power amplifier is operated in
Normal mode is to only use the Speakon-type connector CHANNEL A and to connect one
speaker cabinet to pins 1+ and 1–, as described above and the second cabinet to pins 2+ and
2–. Pins 2+ and 2– are only assigned at Speakon-type connector of CHANNEL A. Proceeding
like this facilitates the cabling of speaker systems that are used in active 2-way operation (BiAmp). The correct connection is also indicated at the amplifiers rear panel.

Figure 6.6: Balanced connection of input
Whenever possible, using balanced audio signal feeds at the input of the power amplifier is
always preferred. Unbalanced connections should only be used if the cables are very short and
no interfering signals are to be expected in the vicinity of the power amplifier. In this case,
bridging the screen (shielding) and the pin of the inverting input inside of the connector is
mandatory. Otherwise, a 6 dB drop in level could result. Due to their immunity against
external interference sources, such as dimmers, mains connections, HF-control lines, etc.,
using balanced cabling and connections is always preferable.

Notice!
100V: 2 x 2500 W means each channel of the amplifier may be loaded with a maximum 2500
W loudspeaker loads.
For example, 50x loudspeakers per channel, each loudspeaker with a power rating of 50W/
100W.
8.2
Mains operation & resulting temperature
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.
Mains Operation & Resulting Temperature tables allow the determination of power supply and
cabling requirements. The tables are 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. Power consumption is direct proportional
for other mains voltages. The following conversion factors are meant for easy conversion: 100V
= 2.3; 120V = 1.9; 240V = 0.96
