CLIP-LED

    The CLIP LED lights up when the input signal is driver too high. In this case, turn down the TRIM 
control and, if necessary, check the setting of the channel EQ.

SOLO

    The channel fader determines the level of the channel signal in the main mix (or submix).

    The SOLO switch is used to route the channel signal to the solo bus (Solo In Place) or to the PFL bus 
(Pre Fader Listen). This enables you to monitor a channel signal without affecting the main output signal. 
The signal you hear is sourced either before (PFL, mono) or after (solo, stereo) both the pan control and 
the channel fader (see chapter 2.3.6 “Level meters and monitoring”).

Fig.  2.5: Stereo channel 
inputs and LEVEL switch

    Each stereo channel has two balanced line level input on 
1/4" connectors for left and right channels. If only the connector 
marked “L” is used, the channel operates in mono. Stereo 

channels are designed to handle typical line level signals.

Both input can also be used with unbalanced jacks.

LEVEL

    For level matching, the stereo inputs feature a LEVEL switch 
which selects b4 dBu and -10 dBV. At -10dBV (home-
recording level), the input is more sensitive than at +4 dBu 
(studio level).

    In principle, the aux sends of the stereo channels function in just the same way as those of the mono 
channels. As aux send paths are always mono, the signal on a  stereo  channel is first summed to mono 
before it reaches it reaches the aux bus.

2.2.3 Aux sends stereo channels

    The equalizer of the stereo channel is, of course, stereo. The filter characteristics and crossover 
frequencies are the same as those of  the mono channels. A stereo equalizer is always preferable 
to mono equalizers if frequency correction of a stereo signal is needed. There is often a discrepancy 
between the settings of the left and the right channels when using separate equalizers.

2.2.2 Equalizer stereo channels

2.2.4 routing switch, solo and channel fader

    The function of the BAL(ANCE) control corresponds to the PAN control in the mono channels.

    The balance control determines the relative proportion between the left and right input signals before 
both signals are routed to the main stereo mix bus.

    The MUTE/ALT 3-4 switch, the MUTE-LED, the CLP-LED, the SOLO switch and the channel fader 
function in the same way as the mono channels.

    Also a rule, solo signals are monitored via the control room output and headphones connector and are 

displayed by the level meters. If a also switch is pressed, the signals from the tape input, Alt 3-4 and main 

mix are blocked from the control room outputs, the headphone connector and the level meter.

The PAN control in the channel strip offers a constant power characteristic. This means that 

the signal is always at a constant level, irrespective of its position in the stereo panorama. 

If the PAN control is moved fully left or right from center, the level increases by 4 dB in that 

channel. This signal is not louder. For this reason, with the solo function activated (Solo In 

Place), audio signals from the channels with PAN controls that have not be moved fully to 

the left or right are displayed at a lower volume that in the PFL function.

MAIN SOLO 

    The MAIN SOLO LED lights up as soon as a channel or aux send solo switch is pressed. The MODE 
switch also has to  be set at “solo”.

The PFL LED indicates that the peak metre is set to PFL mode.

PHONES

    You can connect headphone to this 

TRS connector. The signal on the PHONES connection is 

sourced from the control room output.
