Functions

Microphone Channels

1. Mic input

Electronically balanced XLR-type input for connecting low impedance

microphones. The input has extremely low noise hum. 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’s level control and the master faders are at their minimum settings.

Otherwise, unpleasant plug-in noise can occur.

2. Mic level control

Use these controls to adjust the levels of microphone channel 1 and 2.

3/4/5. Channel EQ Hi/Mid/Low controls

Each channel is fitted with 3-band EQ. The Hi (3), Mid (4) and Bass (5) bands

have their center frequencies fixed at 5 Khz, 800 Hz and 70 Hz respectively. All

three bands have up to 26dB cut and up to 12 dB boost and have 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

Fig. 8 equalizer control usually produce the best results. Try to avoid excessive

enhancement of the Mid band.

6. Send level control

Allows you to adjust the level of the according channel in the send mix.

7. Mic On/Off switch

Allows you to switch both microphone channels on or off.

8. Talkover switch

If the talkover function is active, channels 1-4 are automatically attenuated by 12dB while speaking in the

DJ-microphone.
