(14) Determine the channel volume using the 60-MM CHANNEL fader.
(15) Pressing the PFL key routes the respective input so that it can be monitored on the headphones
(corresponding LED is lit ). You can also dial up several channels and listen to them simultaneously
(see also chapter 2.4 HEADPHONE section ).

(16) The VOL 1 control is used to adjust the output volume on the MAIN 1 output (see 41 ).
(17) The VOL 2 control is used to adjust the output volume on the MAIN 2 output (see 46 ).
(18) To adjust balance on the MAIN 1 output, use the BAL 1 control.
(19) You can read off the MAIN 1 audio signal volume level on the LEVEL METER.
(20) The POWER switch powers the PRO MIXER on. You should always make sure that the
POWER switch is in the Off position when initially connecting the unit to the mains.
•
Please take note: Merely switching the unit off does not mean that it is fully
disconnected from the mains. When not using the unit for prolonged periods of time,
please unplug the unit s power cord from the power outlet.
•
Always turn the power amps on last to avoid inrush currents that can easily damage
your speakers. And, to avoid sudden and unpleasant surprises for your ears, make sure
there is no signal at the PRO MIXER before turning on the power amps. To be sure,
slide all the faders to the bottom and switch all controls to the zero position.
2.4. Headphone section
The PFL signal is your headphone signal used to monitor music without influencing the MAIN
signal (PFL = Pre Fader Listening).
(21) This is the unbalanced PHONES connector for your headphones. Your headphones
should have a minimum impedance of 32 Ohms. For example, the headphones are
ideally suited for this purpose.
(22) If the MODE switch is in the SPLIT position, the PFL signal is on the left, and the
MAIN signal is on the right. The MIX control (see 23 ) has no function in this case.
While in STEREO mode, you can alternate between MAIN and PFL signals using the
MIX control.
