•Make sure you don’t use the wrong kind of cables or defective cables.
•Make sure that the signals into the mixer are balanced, otherwise hum could be created.
•Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear.
•Make sure that the available voltage is not higher than stated on the rear panel.
•Make sure that the power-cord is never crimped or damaged. Check the system and the power-cord
from time to time.
•In system setup, the amplifier's output power must be 50%-100% more than the loaded
loudspeakers rated power.
•Please turn off the power switch, when changing the power cord or signal cable, or select the input
mode switch.
•Extreme frequency boosts in connection with a high input signal level may lead to overdriving your

Installation
Remove all packing materials from the Powermix 2. Check that all foam and plastic padding is removed.
Connect all cables.
Always disconnect from electric mains power supply before cleaning or servicing.
Damages caused by non-observance are not subject to warranty.
Mono Input Channels
Channels 1-6 are mono, with a choice of balanced Mic, Line or Insert inputs.
Stereo Input Channels
A further 8 Line inputs are configured as 4 stereo input channels. These are ideal for
accepting outputs from MIDI and other electronic instruments.

9
1. MIC
Electronically balanced XLR-type inputs for connecting low-impedance microphones.
The input provides extremely low noise and low hum signal processing. When
connecting a microphone make sure that the pin assignment is correct. Always make
sure to read the manual of the microphone you want to connect. The XLR-inputs are
not suitable for connecting an additional mixing console, FX-unit, etc. You have to use
the LINE-inputs, when connecting this kind of equipment.
2. LINE
Electronically balanced inputs for connecting a keyboard, CD player, mixer, etc. You
can connect balanced or unbalanced signal sources to the Line input. Do not connect
signal devices to a channel’s MIC and LINE input at the same time. This will cause
mutual interference, which results in level reduction.
Note: When connecting signal sources, please make sure that the
corresponding channel faders and the master faders are at their minimum
settings. Otherwise unpleasant plug-in noise can occur.
3. INSERT
Insert for external device, effect, compressor etc.
4. GAIN
Mic Channel input level is determined by the Gain control.
With the Gain control you can adjust the MIC or LINE input-sensitivity, while optimally
matching the incoming signals to the mixer’s internal operation level. When dealing
with very low input levels (example vocal recordings or distant sound sources) the
high gain is extremely profitable.
How to set the Input level:
1) Set the gain control and the corresponding channel fader to their minimum setting.
2) Connect the desired sound source (CD player, microphone, ect) to the
corresponding MIC or LINE input.
3) Play the sound source at its highest volume setting; respectively, sing or speak as
loud as possible directly into the microphone.
4) While doing so, adjust the input level using the gain control, so that during the
loudest passages the PEAK LED is just not lit, but the SIGNAL-LED lights
constantly.
This basic channel setting leaves you at least 8dB headroom. This means, you have
at least 8dB before signal clipping. If you want to make further adjustments to the
channel’s EQ setting, you should repeat step 3and 4again.
5. Low Cut Button
If you push the “Low Cut” button, it connects to the filter. The Powermix 2 has a built-
in 62Hz / 18dB OCT high pass filter to cut the undesirable low frequencies. This
function can be used to cut the humming sound or to prevent resonances of low
frequencies, when the speakers are placed in a closed place.
6 / 8 / 9. Equalizer SECTION (HI / MID / LOW)
The mixer’s Equalizer section allows shaping of the incoming audio signal. All mono
input channels are fitted with 3-band EQ. The upper (6) and lower (9) shelving
controls have their frequencies fixed at 12 Khz and 80 Hz respectively. The Mid range
control (8) has a peaking response frequency at 2.5 Khz. All 3 bands have up to 15
dB cut and boost, with a centre detent for “OFF”. Turning the Equalizer level control to
the right amplifies the frequency range, turning to the left attenuates the signal. Minor
changes to the Equalizer control usually produce the best results. Try to avoid

10
excessive enhancement of the MID band.
7. Parametric Mid
This Control is for adjusting the filter frequency (100 Hz–8kHz) for the equalizer in the
midrange
10 / 11 AUX 1 FX 1 / AUX 2 FX 2
The FX control allows you to change the AUX FX 1/2 Level to the FX Mix.
The range is from 0 – 10
Using the FX1/2 control lets you route the corresponding input signal to the integrated
digital effects units FX1 or FX2 at variable levels. In this way assigning special effects
to musical instruments or vocals is fairly simple. When establishing an effect-mix, it’s
advisable to start with all FX-controls set to their center position. You can further
increase or reduce the effect’s intensity, depending on your personal preferences.
Please make sure to carefully monitor the PEAK LED’s in the FX1/2 channels during
a performance.
12. AUX 3
The Aux control allows you to adjust the Aux 3 Channel to the Aux Mix. The range is
from 0 – 10
13. MONITOR
This control allows you to adjust the Monitor Mix and send it with Master Monitor
Fader to the Monitor Amp. The range is from 0 – 10.
14. PAN
By using the PAN control you can change the input signal’s position within the stereo
image. When the PAN control is set to center position, the audio signal is equal for
both the left and right buss.
15. PFL
The PFL button (pre fade listening) is designed to override the main signal, so
although an individual channel is heard, it is not in complete isolation. If you push the
PFL button, regardless of the Aux rotary control, you will get the complete signal in
your headphone/monitors. This is useful, because the recording engineer hears some
of the main signal. So the channel is not only heard, but also in context. Pressing this
button assigns a channel’s audio signal to the PFL bus. Simultaneously assigning
more than one channel to the PFL bus is possible, while the individual channel’s
volume fader setting is not recognized (PRE FADER LISTEN). Once a PFL button is
pressed, the master display automatically enters PFL/PGM mode. This allows you
setting a signal’s correct level or making special EQ-adjustments without the need of
including it in the main mix.
16. PEAK Indicator
The Peak indicator shows a channel’s incoming signal level at all times. If the red
PEAK LED frequently blinks or constantly lights, the corresponding channel is likely to
enter clipping and you have to reduce amplification using the gain control. The peak
LED lights at a level of 8 dB below the occurrence of overdrive. Make sure that the
Peak LED (+12dB) lights only briefly during dynamic peaks, indicating a state of over
modulation (distortion at extremely high volumes). In this case, check the output
signal of your mixer and turn down the input gain control. a channel LED (16)
illuminates, when a channel is going into overload. You don’t want the overload light
to come on, except very intermittently during a take or mix. If it does not light
persistently, reduce input gain.

11
17. SIGNAL Indicator
The Signal indicator shows a channel’s incoming signal level at all times. The green
Signal LED will according to the rhythm of the incoming signal. If not, you should
increase the input level by using the gain control. The Signal LED lights 30dB below
clipping.
18. Channel Fader
A high-quality true logarithmic 60mm fader, which controls the volume of a single
channel and to establish an accurately proportioned mix of all input signals. The
channel faders should be positioned within the range of -5dB to 0dB, leaving you with
sufficient room to allow precise matching of differences in the channel’s level settings.
The overall volume is set with the master fader. Even though the channel faders offer
an additional gain of +10dB, it is better not to exceed the +5dB position.
19. FX 1 Fader
A high-quality true logarithmic 60mm fader,
which controls the FX 1 output level.
20. FX 2 Fader
A high-quality true logarithmic 60mm fader,
which controls the FX 2 output level.
21. AUX 3 Fader
A high-quality true logarithmic 60mm fader,
which controls the Aux output level (65).
22. MONO OUT Fader
A high-quality true logarithmic 60mm fader,
which controls the Mono output level (78).
23. MONITOR Fader
A high-quality true logarithmic 60mm fader, which
controls the monitor amplifier output level (89).
24 / 25. MASTER Fader
A high-quality true logarithmic 60mm fader, which controls the Left and Right amplifier output levels (87+88).
LEFT and RIGHT Stereo fader for adjusting the overall volume as well as the output level of the internal
power amplifiers and the MASTER A OUTPUTS (79).
Please, make sure to close the fader of the corresponding input channel or at least the MASTER
controls before connecting any audio signal sources. This will save yourself, your audience, and
your equipment from unnecessary stress resulting from plug-in noise.

12
26 / 28. 7-BAND EQUALIZER (Left and Right)
All 7 frequency bands (80Hz, 250Hz, 630Hz, 2,5 KHz, 4 KHz, 8
KHz, 16 KHz) provide a ±12dB amplification/attenuation. You
can change the overall sound, thus meeting your requirements
for different locations. If you want your sound to have more
bass, you have to boost the low frequency range, using the
80Hz or the 250Hz controls. If you experience too much bass,
lower the levels of the 80Hz and 250 HZ controls.
If the mid-range sounds a bit nasal, try attenuating the 630 Hz,
2,5 Khz and 4 Khz controls by some decibels.
If you want to have a clear and highly intelligible sound, you
should increase the level setting of the 8kHz or 16kHz band a
bit. When using the equalizer, less attenuation is better than a
great change of the control settings.
27 / 29. EQ On/Off (Left and Right)
You can press the EQ button (27/29) to turn this section on.
30 Feedback Filter 100 Hz – 8 KHz
The Feedback control allows you to adjust the Filter from 100
Hz – 8 Khz on Aux 3.
31 Feedback Filter On/Off
You can press this button to turn the Feedback Filter on.
32. Phones
This control allows you to adjust the headphones’ volume. Phones controls 79, range 0-10
Caution: Depending on the type of headphones connected to the phones jack, the Powermix is capable of
producing very high output levels via the phones output. Therefore, make sure to turn the control all the way
to the left (minimum setting) before connecting the headphones.
Be aware of the fact that listening to loud sound pressure levels over a longer period of time leads to
hearing-damage!
33. FX 1 To Monitor
This control allows you to adjust the FX 1 level to the Monitor Mix.
34. FX 2 To Monitor
This control allows you to adjust the FX 2 level to the Monitor Mix.
35. LED VU Meter
36. PFL
Pre-fade listening Aux 3.
The PFL button (pre fade listening) is designed to override the main signal, so although an individual
channel is heard, it is not in complete isolation. If you push the PFL button, regardless of the Aux rotary
control, you will get the complete signal in your headphone/monitors. Also see (38)
37. Aux 3 Post
This button allows you to make a Master Mix, without using a Channel’s fader.
38. PFL
The PFL button (pre fade listening) is designed to override the main signal, so although an individual
channel is heard, it is not in complete isolation. If you push the PFL button, regardless of the Aux rotary
control, you will get the complete signal in your headphone/monitors. This is useful, because the recording

13
engineer hears some of the main signal. So the channel is not only heard, but also in context. Pressing this
button assigns a channel’s audio signal to the PFL bus. Simultaneously assigning more than one channel to
the PFL bus is possible, while the individual channel’s volume fader setting is not recognized (PRE FADER
LISTEN). Once a PFL button is pressed, the master display automatically enters PFL/PGM mode. This
allows you setting a signal’s correct level or making special EQ-adjustments without the need of including it
in the main mix.
39. Stereo Return
This control allows you to adjust the Stereo
Return. The range is from 0 – 10
40. 2 Track to Aux 3
This control adds 21 to the AUX mix, range 0-10
41. 2 Track to Master
This control, range 0-10 controls 81
42. PROTECT LED
The red Protect LED lights when one of the power amplifiers’ extensive protection
functions - against thermal overload, HF-induction, DC at the outputs. When the
Powermix 2 is in protect mode, the speaker outputs are muted and the inputs of the
power amplifier are short-circuited to prevent the amplifiers from being damaged. In
this case you should first check if the frontal and/or rear ventilation louvers are
blocked. Another cause for the activation of the protect functions might be, that you
have connected more than two 8 Ohms speaker systems per power output. Please
also disconnect the SPEAKON connectors and check the speaker cables for short
circuit. During the power-on operation, the PROTECT LED always lights for about two
seconds. This is normal. It indicates that the PowerMix’s protection circuitry is
operational.
43. LIMIT LED
When the red Limit LED blinks, means the internal power amplifiers are operated at
their limits.
Occasional blinking of the LED is acceptable, since the amplifiers’ limiters prevent
distortion. Continuous lighting indicates that degradation in the outputted sound is
likely to happen. In that case, you should reduce the master level.
44. POWER LED
The blue Power LED lights when the PowerMix is turned on. If, after switching the
PowerMix on, the LED does not light, make sure that the mains plug is plugged in
correctly. If the LED still doesn’t light up, please contact your DAP Audio dealer.
45. Phantom Power LED
After switching on the mixer, the yellow LED above the switch must not light up. In this case, both balanced
and unbalanced microphones can be connected. These microphones may be damaged.
46. Phantom Power
You can press this button to turn the PHANTOM POWER +48 V on. Do not connect any unbalanced
microphones with the microphone phantom power switched on. The yellow LED PHANTOM POWER +48 V
(45) lights up.

Connection Cables
Take care of the connector cables, always holding them by the connectors and avoiding knots and twists
when coiling them: This gives the advantage of increasing their life and reliability, which is always to your
advantage.
Periodically check that your cables are in good condition, that they are correctly wired and that all their
contacts are perfectly efficient: a great number of problems (faulty contacts, ground hum, discharges, etc.)
are caused entirely by using unsuitable or faulty cables.
