4
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.
Please turn off the power switch, when changing the power cord or signal cable, or select the

Extreme frequency boosts in connection with a high input signal level may lead to overdriving
your equipment. Should this occur, it is necessary to reduce the input signal level by using the
INPUT control.
To emphasize a frequency range, you don’t necessarily have to move its respective control
upward; try lowering surrounding frequency ranges instead. This way, you avoid causing the next
piece of equipment in your sound path to overdrive. You also preserve valuable dynamic reserve
(“headroom”)
Avoid ground loops! Always be sure to connect the power amps and the mixing console to the
same electrical circuit to ensure the same phase!
If system is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
If the system has been exposed to drastic temperature fluctuation (e.g. after transportation), do
not switch it on immediately. The arising condensation water might damage your system. Leave
the system switched off until it has reached room temperature.
If your Dap Audio device fails to work properly, discontinue use immediately. Pack the unit
securely (preferably in the original packing material), and return it to your Dap Audio dealer for
service.
Repairs, servicing and electric connection must be carried out by a qualified technician.
For replacement use fuses of same type and rating only.

Connect all cables.
Always disconnect from electric mains power supply before cleaning or servicing.
Damages caused by non-observance are not subject to warranty.
Functions
1. MIC
Electronically balanced XLR-type input for connecting low impedance
microphone. The input has exremely low noise and hum 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- input is not suitable for connecting an additional mixing
console, FX- unit, etc. You have to use the LINE-inputs, when connecting this kind
of equipment.
Note: When connecting signal sources, please make sure that the corresponding
channel faders and the master faders are at minimum settings. Otherwise
unpleasant plug-in noise can occur.
2. MIC Channel ON Switch
Use this switch to enable the Mic channel.
3. DJ MIC Level
Controls the volume of the Microphone channel.

7
4. Selection Switch (CD/Line)
With this switch you can select multiple devices you have connected to your
DS-CM-4.
5. Selection Switch (Phono/Line)
With this switch you can select multiple devices you have connected to your
DS-CM-4.
6. Channel Fader
A logarithmic 50mm fader, which controls the volume of its’channel. The faders
should be positioned within the range of -12dB 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 +6dB, it is better not to exceed the +0dB position by
default.
7. PFL
The PFL button (pre fade listening) is designed to route the channel input to the
monitor section independent of the individual channel’s volume fader setting. It
It is possible to assign more than one channel simultaneously to the PFL bus.
8. Crossfader
The crossfader allows you to mix evenly from channel 2 to channel 3.
9. Balance
Use to set the balance between the Left and right master output.
10. Master
You can adjust the output signal to the Master Output (26).
11. Power LED
Indicates that the DS-CM-4 is active.
12. Power On / Off
Do not supply power before the whole system is set up and connected properly.
13. Output Signal VU Meter
This meter is a multi-step LED; respectively the blue LEDs show –26, -21, -18, -15,
-10, -5dB. The red LED shows +0, +3, +6dB. The accurate level indication allows
you to monitor the output signal level at anytime, and match with other
devices.
14. EQ
All 7 frequency bands (60Hz, 250Hz, 1 KHz, 4 KHz, 12 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 60Hz or
the 250Hz controls. If you experience too much bass, lower the levels of the
60Hz and 250HZ controls. If the mid-range sounds a bit nasal, try attenuating
the 250Hz, 1Khz and 4Khz controls by some decibels. If you want to have a
clear and highly intelligible sound, you should increase the level setting of the
4kHz or 12kHz band a bit. When using the equalizer, less attenuation is better
than a great change of the control settings.
15. EQ On/ Off
Use this switch to bypass the EQ section.
16. CF Monitor
Use this control to make a headphone mix between your PFL and your master
signal.
17. Phones
This control allows you to adjust the headphones’ volume.
18. Headphone
You can connect a pair of headphones with an impedance of 32 - 600 Ohm to
the headphones connector. It is a 6,3mm/ 1/4” TRS socket, wired as Tip=left,
Ring=right and sleeve = ground.
Caution: Depending on the type of headphones connected to the Headphones jack, the ds-cm-4 is
capable of producing 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!

Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate a 120V specification product on 230V power, or vice versa.
Connection Cables
Take care of your 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.
Periodically check your cables. A great number of problems (faulty contacts, ground hum, discharges,
etc.) are caused entirely by using unsuitable or faulty cables.
