13. STEREO INPUT
A (CD/MD):
Unbalanced stereo inputs for connecting LINE level devices like for example: CD-Players,
MD-Players, Tape Decks, PC Soundcards, etc.
B (phono): only channels 4/5
- stereo inputs with RIAA equalization for the connection of magnetic turntable pickups.
Caution: Make sure to connect magnetic turntable pickup systems only. These inputs
are not suitable for connecting high-level audio signal sources like CD-Players, etc.!
Do not forget to connect the turntable’s ground wire to the PHONO GROUND binding
post. Otherwise it is likely that you are faced with interference noise.
Tip: When using turntables, high acoustic output levels can result in unwanted feedback.
You can avoid this from happening during a performance by rehearsing the latter scenario.
Set the sound system to the desired maximum output level while using a turntable as sound
source. Feedback mostly generates in the low-frequency range, for that the RIAA-equaliza-
tion of the phono inputs amplifies the signal by up to approx. +20dB. Therefore, it is good
advice not to position turntables and mixer gear directly in front of the loudspeaker systems.
Pieces of plastic foam or special shock absorbers may be a remedy. But when using them
make sure not to cover any ventilation louvers of the equipment.
14. INPUT SELECT
Simultaneously connecting audio signal sources to both inputs (A and B) is possible. Using
the INPUT SELECT switch lets you select whether you want to reproduce the signal of
source A (CD/MD) or B (turntable for channels 4/5 or CD/MD for channels 6/7). Before
connecting a sound source, make sure to set the corresponding input’s CHANNEL FADER
(22) to its minimum position. This prevents the connected loudspeaker systems and the
audience from being abused by nasty crackling noise.
15. GAIN
The setting of this control defines a channel’s input sensitivity. It is fairly simple to match
the input level of different audio signal sources by individually adjusting the GAIN controls
of each channel, so that the signal LED “SIG” is constantly lit while the peak LED “PK” lights
briefly during peak levels only. GAIN adjustment should always be carried out with
EQ-controls set to their center position. This leaves enough headroom for later EQ-adjust-
ment without clipping. Using the PFL/PGM Split function of the master display lets you trim
a channel’s input level setting more precisely. Engage a PFL button and the yellow PFL/PGM
LED beneath the master display will light while the right LED-chain indicates the level of
the momentarily running master signal (PGM) and the left LED-chain indicates the PFL-bus’
level.
Tip: The correct use of the PFL/PGM Split function during mixing facilitates the matching
of different signal levels to a great extent. Presuming that during playback you have set the
channel faders to their maximum position, pressing the PFL-button of the channel that you
are about to adjust the level for, lets you monitor the different levels on the master display.
The left LED-chain indicates the level of the PFL-channel while the right LED-chain displays
the level of the momentarily played back audio signal. Using the GAIN-controls this allows
optimally matching the two signal levels.
