SoURCe LIne (USB) / AUX Switch with built-in red LED to select the input source for the INPUT 1 channel. If the switch is not pressed, the line or USB-input on the back of the device is selected as the signal source; in the pressed position, the AUX input on the front panel is selected (LED is on).

GAIn InPUT 1 - 4 To harmonise playback devices (CD player, MP3 player etc. ) with different output levels, adjust the input gain of the INPUT channels 1 - 4 with the help of this GAIN control. This also applies to the playback signal from the USB-interface in channel 1.

SIGnAL LeD InPUT 1 - 4 The signal LED lights up green when an audio signal is present at the input of the respective channel. The LED lights up red when the optimum volume level (0 dB) is achieved.

VoLUMe InPUT 1 - 4 Volume control for channel INPUT 1 to 4.

CUe InPUT 1 - 4 Cue switch with built-in red LED for INPUT channels

1 - 4. If the switch is pressed (LED is on), the input

signal is routed to the headphone output on the front panel of the device. The signal is sourced before the volume control of each channel, therefore it is independent of the setting of the volume control.

TALKoVeR Talkover feature for microphone channels 1 and

2. If the TALKOVER knob is turned fully to the left,

the Talkover feature is disabled. The further the TALKOVER knob is turned to the right, the stronger the signals connected to INPUT 1 - 4 will be suppressed by the incoming microphone signal. The threshold value is determined using the T/O LEVEL control set on the rear panel (sensitivity with which the Talkover feature reacts to the incoming microphone signal). The Talkover feature is not available for the ZONE output when a signal source from INPUT 2 - 4 is selected using the SOURCE switch.

MASTeR LeVeL Volume control for the MASTER channel.

MASTeR eQ HIGH Equalizer high band for the MASTER channel. When turned to the left, levels are lowered, when turned to the right, they are raised. In the centre position (resting point), the equalizer is inactive.

LeVeL MeTeR Level meter display with 2 x 10 LED segments (left / right). Once the peak LED (PK) lights up, the device is operating at the distortion limit. It is not critical if the LED lights briefly at peak levels for the incoming signal, however continuous illumination should be avoided by reducing the volume.

MASTeR / zone SWITCH (WITH BUILT-In LeD) When the switch is not pressed, the LEVEL METER displays the level of the MASTER channel. When the switch is pressed ,the LEVEL METER displays the level of the ZONE channel and the built-in LED is on.

IeC PoWeR SoCKeT WITH InTeGRAL FUSe HoLDeR IMPORTANT INFORMATION: BEFORE using this equipment, make certain that the mains voltage of your energy utility and the operating voltage of the device match! Always replace the fuse only with a fuse of the same type with the same rating (printed on the rear panel)! If the fuse blows repeatedly, please contact an authorised service centre.

eMeRGenCY InPUT Symmetrical terminal block connector for an acoustic emergency response system (terminal block included). As soon as there is an audio signal with line-level signals, all microphone and line inputs are muted, and the emergency signal is directly connected to the MASTER and ZONE line outputs. The volume control on the MASTER and ZONE channels are then inactive.

LeVeL eMeRGenCY InPUT Adjust the volume of the emergency signal with a suitable screwdriver.

ReC oUTPUT L/R Unbalanced stereo line output on RCA connectors (left / right). The signal from the REC output consists of the sum of the signals of the inputs MIC 1 / 2 and INPUT 1 - 4 and FOH. The output level is independent of the setting of the volume control of the MASTER- output; the signal is sourced before the EQ, therefore, it remains unprocessed.

oUTPUT MUTe Terminal block connector for connecting a potential free contact or a mute switch (terminal block included). When the contact is closed, all input channels are muted except for the EMERGENCY INPUT. The mute feature is only available for the MASTER output.

MASTeR oUTPUT L/R BALAnCeD Balanced stereo output with XLR jacks (left / right). The signal of the MASTER output consists of the sum of the signals from the MIC 1 and 2 inputs, and INPUT 1 to 4.

MASTeR oUTPUT L/R UnBALAnCeD Unbalanced stereo output with RCA jacks (left / right). The signal of the MASTER output consists of the sum of the signals from the MIC 1 and 2 inputs, and INPUT 1 to 4.

MASTeR MAX LeVeL Adjust the maximum volume of the MASTER output with a suitable screwdriver.

zone oUTPUT BALAnCeD Balanced stereo output with XLR jacks (left and right). The signal from the ZONE output may be the sum of the signals of the MIC 1 - 2 inputs and INPUT 1 - 4 (ZONE SOURCE switch 21 on the front of the unit set on MIX), or the signal of one of the INPUTS 2 - 4 (ZONE SOURCE switch 21 on the front of the device set to one of the INPUTS 2 - 4).

zone oUTPUT UnBALAnCeD Unbalanced stereo output with RCA jacks (left / right). The signal from the ZONE output may be the sum of the signals of the MIC 1 - 2 inputs and INPUT 1 - 4 (ZONE SOURCE switch 21 on the front of the unit set on MIX), or the signal of one of the INPUTS 2 - 4 (ZONE SOURCE switch 21 on the front of the device set to one of the INPUTS 2 - 4).

2 - 4 (ZONE SOURCE switch 21 on the front of the

device set to one of the INPUTS 2 - 4).

zone MAX LeVeL Adjust the maximum volume of the ZONE output with a suitable screwdriver.

zone eQ HI Equalizer high band for the ZONE channel. When turned to the left, levels are lowered, when turned to the right, they are raised. In the centre position (resting point), the equalizer is inactive.

InPUT 1 LIne L/R Unbalanced stereo line input on RCA connectors (left / right).

MIC InPUT 1 - 2 Balanced microphone inputs INPUT 1 and 2 with

6.3 mm jack. Both microphone inputs are equipped

with a 12 V phantom power.

T/o LeVeL The threshold value of the Talkover is determined using the T/O LEVEL control (sensitivity with which the Talkover feature reacts to the incoming microphone signal). The Talkover feature is available for the MASTER and ZONE line outputs (SOURCE switch set to MIX).

USB The USB-interface (USB 1.1) allows for the mixer to be used as an audio interface. In other words, audio recording and playback can be done through a connected computer with Windows Operating System (Windows XP, Vista, 7, 8) and Apple Macintosh OS 10.5 or higher. Separate drivers are not necessary for the installation. Once connected to a suitable USB port on your computer (USB 1.1, USB 2.0), the drivers are auto- matically installed, the audio interface is detected as "USB Audio CODEC" interface on both Windows and Apple Macintosh computers. The recording signal consists of the sum signal and is sourced before the master level control and the max level control, and is therefore indepen- dent of it. Audio playback is via the line channel INPUT 1. For this, the switch 55 must be pressed on the back panel (USB) and the switch 8 (LINE) on the front of the unit should not be pressed.

USB / LIne Switch for selecting the signal source for the line channel INPUT 1. In pressed position, the USB- interface (54) is selected, if not pressed, the line input (51) is selected as the signal source.
