3.2 On/Off switch
The On/Off switch is a rocker-type switch. It is located on the right side of the
front panel. To turn the amplifi er on, push in on the upper part of the switch. This
initiates start-up by activating the inrush current limiter. During power up the
clip and signal LEDs will light up in red for a few seconds. To turn the amplifi er
off, push in on the lower part of the switch.
The amplifi er is switched on. The amplifi er is switched off.
NOTE: This switch does NOT disconnect the amplifi er from mains.
The switch initiates start-up by activating the current limiting function. As soon
as the power amplifi er is connected to the mains power supply, a voltage is
supplied to both the line-fi lter and the fused input of the controllable rectifi er.
Disconnecting the amplifi er from the main power supply can only be achieved
by physically separating the amplifi er from the mains by pulling the mains plug.
The mains plug therefore has to be freely accessible. Disconnect the mains plug
from the mains during a lightning storm or when the amplifi er remains unused
or un-supervised for a prolonged period of time. Alternatively, you can disconnect the amplifi er via an external all-pole disconnection from the mains.
If a power cut occurs while the amplifi er is switched on, it will restart automatically once the power supply has been restored. All settings prior operation
to the loss of power will be maintained.

3.4 Cooling
Under normal operation of the power amp, overheating should never be a
problem. The air is taken in from the front and out through the back. It is of
course essential that while the power amp is running air is able to circulate
around it freely.
The effi ciency of the cooling will depend on the immediate environment (e. g.
an enclosed rack, direct sunlight) and on whether the front fi lter is clogged. If
the amp is installed in a case the open area at the back of the case must be at
least 140 cm². This area should be in line with the amp.
3 INSTALLATION
If this can not be achived a forced ventilation system has to be used.
3.5 Wiring
3.5.1 Input Connectors
XLR: Pin 1 = Ground
Pin 2 = Hot (inphase, +)
Pin 3 = Cold (out of phase, -)
Euroblock connector: Pin 1 = Hot (inphase, +)
Pin 2 = Ground
Pin 3 = Cold (out of phase, -)
Make sure to always use high-quality symmetrical (balanced) shielded cable to
ensure maximum audio quality.
Take special care not to use the two XLR and Euroblock input connectors of a
specifi c channel at the same time. This could lead to volume and audio quality
loss and could damage the connected signal sources.

WARNING !
SPEAKON connectors marked with the lightning fl ashes indicate high voltages that are potentially life threatening.
Wiring to these terminals requires installation by an instructed person or
the use of ready-made leads or cords.
Custom wiring should only be carried out by qualifi ed personnel.
To prevent electric shock, do not operate the amplifi er with any of the conductor portion of the speaker wire exposed.

4.1 Indicators
4.1.1 On LEDs
Under normal operation, after the amp has started, the green power LEDs are
permanently lit.
4 OPERATION
4.1.2 Signal / Protect LEDs (multifunctional)
The green Signal LEDs are illuminated when the voltage level at the output
reaches approx. 4 V; this corresponds to a power of approx. 4 W into a 4 Ohm
load. The channel signal LEDs are illuminated red when the amplifi er is in Protect
Mode (Mute), for example because of persistent DC-voltage at the outputs or
overheating.
4.1.3 I-Out LEDs
The brightness is proportional to the output current in the channel. Output current of approx. 1 A lights up the LED at its lowest brightness level, while full
brightness corresponds to the maximum rated current.
4.1.4 Clip LEDs
This LED indicates an overloading of the amplifi er when the power output level
is to high.
P. 15
USER MANUAL
Q-POWER SERIES

4.2 Controls
4.2.1 Volume Control
A volume control with 41 notched settings controls the audio signal. These
settings have been selected to correspond to human hearing characteristics
(logarithmically) and therefore guarantee an optimal range of settings for
practical applications. Each channel can be set individually.
4 OPERATION
Set the volume to zero before turning on the amplifi er to prevent the occurrence of sudden high volume levels which may cause damage to your hearing
and/or the speakers.
4.2.2 Gain Selector
A switch on the rear of the Q-POWER amplifi ers allows the maximum amplifi ca-
tion attainable to be set directly in the input stage.
4.2.3 Limiter Switch
This switch is located at the rear of Q-POWER amplifi ers. It allows you to activate
the clip limiter function on the channels A/B and C/D respectively.
The Q-POWER amplifi ers have a 26 dB and 32 dB
voltage gain setting along with a 1,4 V sensitivity
setting.
4.3.2 SOA Protection
Whenever the power transistors leave their Safe Operation Area (SOA), the SOAprotection will either switch back the current rail of the respective channel
(Q-POWER 6) or limit the maximum load current in the power transistors
(Q-POWER 10).
4.3.3 DC Protection
Each output of the power amp is constantly monitored for persistent DC voltage
levels. If the 3 V thresholds are exceeded at any of the outputs, the corresponding channel will be muted. If DC was only applied for a short moment, the amplifi er will release mute and work as normal. If DC is applied for longer periods or
several short times the amplifi er will switch to standby mode.
If this happens, switch off the amplifi er, wait until all indicator LEDs extinguish
and switch the amplifi er on again.
4.3.4 DC Servo
To prevent DC Offset at the speaker output the Q-POWER amplifi ers are fi tted
with a DC Servo.
4.3.5 Over Current Protection
Over current is permanently controlled in the output stage. In case of exessive
loading the maximum output current of the amplifi ers is automatically limited.
This improves reliability without degrading sound quality when driving complex loads.
P. 16
4.3 Power Amp Protection Systems
4.3.1 Clip Limiter
If the power amp is overdriven and the limiter is set to on (see section 4.2.3)
the clip detection triggers the Attack-Release-Circuit (ARC). The ARC delivers
the control voltage for the gain reduction.
USER MANUAL
Q-POWER SERIES
4.3.6 Thermal Protection
There are sensors in each amplifi er heatsink in order to ascertain tem perature
data. If a temperature of more than 85 °C is detected at the heat sinks, the input
signal on that channel is reduced proportionally to prevent further heating of
the amplifi er. If the temperature exceeds approximately 100 °C, the main SMPS
is switched off(safety shut-off).
Page 19
Q-POWER
SERIES
4.4 Mains Protections
4.4.1 Inrush Current Limitation
Within approximately 2 seconds of the Q-POWER Amplifi er being switched on,
the inrush current limiter will increase mains current smoothly from nearly zero
to nominal value. This value de pends on program material, output level and
speaker loads.
4 OPERATION
4.4.2 Mains Over Voltage Detection
Mains Over Voltage Detection is always operative. When the mains voltage
exceeds approx. 265 V (230 V operation) or 136 V (120 V operation), the amplifi er will switch off. When the mains voltage returns to nominal value a soft start
occurs.
4.4.3 Mains Failure Detection
Mains Failure Detection is always operative. When the mains supply is interrupted for about 2 mains cycles, the amplifi er will switch off. When the mains voltage
returns to a normal value a soft start occurs.
4.4.4 Fuse Protection
The fuse protection circuit prevents amplifi er shut-down (e.g. by a blown mains
fuse or a triggered circuit breaker) during extremely hard use with all channels
working at very high output power. Without intelligent mains current monitoring and control this could easily happen as the rated output power is several
times higher than the capabilities of the standard mains supply.
In order to prevent any shutdown in extreme situations the amplitude of the
input signals will be reduced which will in return also reduce the mains current
draw.
4.5 Main SMPS Protections
4.5.1 Over Current Protection
The main SMPS (Switched Mode Power Supply) transformer current of your
Q-POWER Amplifi er is continuously monitored. If over current occurs the main
SMPS immediately stops working. Should there be an internal failure this feature
prevents other parts from being damaged.
4.5.2 Thermal Protection
If the temperature of the main SMPS transformer exceeds 90 °C, the main SMPS
is switched off (safety shut-off).
4.6 Fans
The fans mounted in your Q-POWER Amplifi er operate permanently, but as long
as the temperature remains below 40 °C, they run at their slowest speed and can
hardly be heard. The highest detected temperature from any amplifi er channel
controls the speed of the fans. Above 40 °C the speed is increased until it reaches
its maximum value.

4.7 Filter Cleaning
The air intake on the front of your Q-POWER Amplifi er is fi tted with a removable
fi lter system. If the fi lter becomes clogged, the unit will not cool as effi ciently as
it should and may result in reduced output levels.
4 OPERATION
Q-POWER
SERIES
WARNING: Turn off the amplifi er before removing the front frame.
To clean or replace the fi lter just slightly unscrew the fi xing screw (3) without
completely removing it from the front frame (it is held back by a small plastic spacer on the back side of the frame to avoid loosing the screw). Then shift
the front frame slightly to the right. Then you should be able to remove the
frame from the amplifi er completely (pull gently to avoid any bending of the
front frame).

4.8 Mounting the Volume Control Security Cover
It is possible to install a solid protection over the volume controls to prevent
intentional or unintentional changes of the amplifi er volume settings.
WARNING: Disconnect the amplifi er from the mains before installing the
cover.
Q-POWER
SERIES
4 OPERATION
In the original state the holes needed to fi x the security cover on both sides of
the volume knobs are hidden behind the plastic front label. In case you wish to
install the cover please fi rst pierce two holes in the front label to facilitate the
screwing, as shown in the drawings.
To fi nd the exact positions of the holes take the included cardboard template
you will fi nd attached on the last page of this manual and place it on top of
the volume knobs. The positions of the hidden screw holes are indicated on
the template. Then fi rmly pierce and turn with a pointed tool (we recommend a
Philips PH1 recessed head screwdriver) through the cardboard and the label at
these positions to obtain a clean hole. You now should see the metal of the fi ne
pitch thread behind the label.
Then remove the cardboard template and fi x the cover with the two included
M3 recessed threaded screws.
WARNING: Do not use any pointed tools (e.g. screwdriver) with a diameter of
less than 3,5 mm (0,138 in), as they might be stucked too deeply inside the amplifi er and damage components.

Try another speaker and cable.
5.2 Problem: Distorted Sound
Indication:
Output Current LEDs are lit
Signal LEDs responding to signal level
Clip LEDs not lit
A faulty speaker or a loose connection could cause this. Check the wiring
and try another speaker.
The signal source might be clipping. Keep the Q-POWER amplifi ers volume
pots at least halfway up so that the source does not have to be overdriven.
Keep the Q-POWER amplifi ers volume pots at least halfway up and try
changing input sensitivity from 1,4 V to 32 dB or 26 dB with the gain selector on the rear.
Indication:
Output Current LEDs are lit
Signal LEDs responding to signal level
Clip LEDs lit
The amplifi er is overdriven by the signal source. Reduce the input signal
level
P. 20
Indication:
Signal LEDs show red (Protect Mode)
Overheating will cause protective muting. Check for proper ventilation. If
the fans are not running the amplifi er requires servicing.
Persistend DC at the outputs will force the amplifi er in protect mode and
shut down the power supply.
Try to mute or disconnect the signal source and restart the amplifi er (i. e.
switch off the amplifi er, wait until all indicator LEDs extinguish and switch
the amplifi er on again).

5.3 Problem: Hiss / Noise
5.4 Problem: Squeals and Feedback
5 TROUBLESHOOTING
Q-POWER
SERIES
Unplug the amplifi er input to confi rm that the hiss is coming from the
source or from a device upstream. Erratic or popping noises indicate an
electronic fault in the offending unit.
To keep the noise fl oor low, operate the primary signal source at full level
without clipping.
Avoid boosting the signal further between the source and the amplifi er.
Microphone feedback should be eliminated with mixer controls. If noise
continues to build up with no microphone gain, there is a serious fault
in the signal processors or cables. Working in succession from the signal
source towards the amplifi er and check each device in the signal path by
reducing its gain or by unplugging it.

10 Maintenance Information
Cleaning and servicing the inside of the amplifi er must never carry out by unqualifi ed personnel. The amplifi er must never be opened by unqualifi ed personnel.
Cleaning and servicing work on the inside of the amplifi er must only be carried
out by qualifi ed personnel.
Qualifi ed personnel is defi ned as a person who has gained specialised relevant
knowledge of electronic engineering through education, training and experience and who has suffi cient knowledge of all relevant governmental work
safety regulations to be in a position to judge the safe functioning of power
amplifi ers based on technical rules according to IEC 60065.
(IEC 60065 (DIN EN 60065) “Safety Requirements for Audio, Video or simlar Electronic Appliances”)
In order to guarantee the safe functioning of the amplifi er, it has to be checked
regularly depending on its application but at least once a year by a properly
qualifi ed person.
Advice on how to carry out these checks can be found in DIN VDE 0702-1 “Safety
Checks for Electronic Appliances” .
11 Decomissioning
During the decomissioning process of the amplifi er, all legally prescribed rules
and procedures must be adhered to.
