[. . . ] 26 Mains cable for the connection of the unit to the power supply (230 V~/50 Hz) 27 Stereo output REC (phono jacks) for the connection of an audio recording unit; the recording level is independent of the position of the master control (21) 28 Stereo monitor output BOOTH (phono jacks) for the connection of a monitor system 29 Stereo output AMP (phono jacks) for the connection of the amplifier 30 Stereo inputs LINE and CD (phono jacks) for the channels CH 1 to CH 4 for the connection of units with line level outputs (e. Minidisk recorder, CD player, cassette recorder) 31 Stereo inputs PHONO (phono jacks) for the channels CH 1 and CH 3 for the connection of turntables with magnetic system 32 Inputs (6. ) for the connection of mono microphones to the two microphone channels; connected in parallel to the XLR jacks (7) on the front plate 33 GND connection for a common grounding point, e. A defect might have occurred after a drop or similar accident, 3. [. . . ] The red LED above the switch lights up to indicate that the unit is ready for operation. 1 Basic setting of channels CH 1 to CH 4 For an optimum level adjustment of the audio sources connected to the input channels CH 1 to CH 4, turn all gain controls (6) and equalizer controls (1) to mid-position first, and set the ASSIGN switches (13 and 19) to "0" (crossfading function switched off). Button pressed ( ) ­ LED above the button lights up: the LINE input of the channel is selected. 2) With the master control (21) the total level of all connected audio sources is adjusted. 3) The selector button (3) must not be pressed: with this button position the VU meter (2) shows the stereo output level which is present at the master output AMP (29). 4) To control a channel, set the faders (15) of the remaining channels to minimum and feed the audio signals (test signals or music pieces) to the respective input channel. 5) By means of the VU meter control the level of the channel with the fader. The optimum level is obtained if the 0 dB LEDs of the VU meter shortly light up with music peaks. in case of overload the red LEDs light up. After the level adjustment the fader should be set to approx. 2/3 of its maximum position so that there is sufficient control range for fading in and out. 6) If the fader is slided up very much or only very little, the level must be matched by adjusting the input amplification: turn back or turn up the gain control (6) of the channel correspondingly. The input amplification can be adjusted in an optimum way by the display of the pre fader level. For this purpose press the button (3) to switch the VU meter to the display mode "PFL", slide the MIX control (23) to the left stop to position "PFL", and press the PFL button (12) of the channel: the VU meter now shows the signal level of the channel ahead of the channel fader. 7) Release button (3) to switch the VU meter to the display mode "MASTER" again, and adjust the desired sound with the equalizer controls (1) of the channel ­ a 3-way equalizer each for the channel group CH1/CH2 and the channel group CH3/CH4: with the three controls the high range (HIGH controls), the midrange (MID controls), and the bass range (BASS controls) can be boosted (max. If the controls are in mid-position, there is no influence on the frequency response. note: Sound adjustments influence the levels. Therefore, after a sound adjustment, check the channel level by means of the level display and correct it, if necessary. 8) Make the level and sound adjustments for the remaining connected input channels as described above. The LED next to the button lights up as indication. Set the faders (15) of the input channels CH 1 to CH 4 to minimum, and adjust the optimal level with the GAIN control (8) of the channel by means of the VU meter (2). Correct the sound for the microphone (max. [. . . ] 2) To switch the VU meter (2) to the headphone output , press the button (3). Then the VU meter shows the signal selected with the MIX control. The human ear gets accustomed to high volumes which do not seem to be that high after some time. Therefore, do not further increase a high volume after getting used to it. [. . . ]
