2.2.4 Routing switch, solo and channel fader

PAN

The PAN control determines the position of the channel signal within the stereo image. This control features a constant-power characteristic, which means the signal is always maintained at a constant level, irrespective of position in the stereo panorama.

MUTE/ALT 3-4

You can use the MUTE/ALT 3-4switch to divert the channel from the main mix bus to the Alt 3-4 bus. This mutes the channel from the main mix.

MUTE-LED

The MUTE LED indicates that the relevant channel is diverted to the submix (Alt 3-4 bus).

CLIP-LED

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

SOLO

BAL

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 CLIP-LED, the SOLO switch and the channel fader function in the same way as the mono channels.

2.3 Connector panel and main section

Whereas it was useful to trace the signal flow from top to bottom in order to gain an understanding of the channel strips, we now look at the mixing console from left to right. The signals are, so to speak, collected from the same point on each of the channel strips and then routed to the main section all together.

2.3.1 Aux sends 1 and 2

A channel signal is routed to aux send bus 1 if the AUX 1 control is turned up on the corresponding channel.

AUX SEND 1 (MON)

The AUX SEND control MON acts as master control for aux send 1 and determines the level of the summed signal. In the 1204FX, the MON control is called

The SOLO switch (1204FX only) 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

AUX SEND 1.

AUX SEND 2 (FX)

the channel fader (see chapter 2.3.6 “Level meters and monitoring”).

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

2.2 Stereo channels

Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.

SOLO

You can use the SOLO switch (1204FX only) to separately monitor the aux sends via the CONTROL ROOM/PHONES outputs and check these with the level meters.

2.2.1 Channel inputs

Each stereo channel has two balanced line level inputs on ¼" 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 inputs can also be used with unbalanced jacks.

LEVEL

◊If you want to monitor the signal of just one AUX bus, none of the other SOLO SWITCHES should be pressed and the MODE switch must be in the SOLO position (not pressed down).

2.3.2 Aux send connectors 1 and 2

AUX SEND 1

If you use aux send 1 pre-fader, you would usually connect the AUX SEND 1 connector to monitors via a power amp (or an active monitor system). If you use aux send 1 post-fader, proceed as described under

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

2.2.2 Equalizer stereo channels

The equalizer of the stereo channels 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 two 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.

2.2.3 Aux sends stereo channels

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 the aux bus.

AUX SEND 2

connectors

The AUX SEND 2 connector outputs the signal you

picked up from the individual channels using the FX control. You can connect this to the input of an effects device in order to process the FX bus signal. Once an effects mix is created, the processed signal can then be routed from the effects device output back into the STEREO AUX RETURN connectors.
