ALT 3-4 OUTPUTS
The ALT 3-4 outputs are unbalanced and carry the signals of the channels that

you have assigned to this group using the MUTE switch. This can be used to route

a subgroup to a further mixing console for example, or or it could be used as a

recording output working in tandem with the main output. This means you could

record to four tracks simultaneously. The icing on the cake, so to speak, is that

you could connect Y-cables to these four outputs and then connect your 8-track

recorder in such a way that you have 2 x 4 tracks (e.g. channel 1 feeds track 1 and

track 2, etc.). In the first recording pass, you record on tracks 1, 3, 5 and 7 and in

the second pass, on tracks 2, 4, 6 and 8.

CONTROL ROOM OUTPUTS
The control room output is normally connected to the monitor system in the

control room and provides the stereo mix or, when required, the solo signal.

2.4.2 Voltage supply, phantom power and fuse

Fig. 2.15: Voltage supply and fuse

FUSE HOLDER
The console is connected to the mains via the cable supplied which meets the

required safety standards. Blown fuses must only be replaced by fuses of the

same type and rating.

IEC MAINS RECEPTACLE
The mains connection is via a cable with IEC mains connector. An appropriate

mains cable is supplied with the equipment.

POWER
Use the POWER switch to power up the mixing console.

PHANTOM
The PHANTOM switch activates the phantom power supply for the XLR

connectors of the mono channels which is required to operate condenser

microphones. The red +48 V LED lights up when phantom power is on. As a rule,

dynamic microphones can still be used with phantom power switched on,

provided that they are wired in a balanced configuration. In case of doubt,

contact the microphone manufacturer!

After the phantom power supply has been switched on, do not connect
microphones to the mixer (or the stagebox/wallbox). Connect the
microphones before you switch phantom power on. In addition,
the monitor/PA loudspeakers should be muted before activating the
phantom power supply. After switching on, wait approx. one minute to
allow the system to stabilize.

Caution! You must never use unbalanced XLR connectors (PIN 1 and 3
connected) on the MIC input connectors if you want to use the phantom
power supply.

SERIAL NUMBER
Please note the important information on the serial number given in

chapter 1.3.3.

3. Digital Effects Processor

Fig. 3.1: Digital effects module (only UB1204FX-PRO)

24-BIT MULTI-EFFECTS PROCESSOR
Here you can find a list of all presets stored in the multi-effects processor.

This built-in effects module produces high-grade standard effects such as

reverb, chorus, flanger, delay and various combination effects. The integrated

effects module has the advantage of requiring no wiring. This way, the danger

of creating ground loops or uneven signal levels is eliminated at the outset,

completely simplifying the handling. You can route signals to the effects

processor via aux send 2 in the channels and the aux send 2 master control.

The built-in stereo effects processor has the advantage that it does not need to

be cabled up. This eliminates any danger of hum or level mismatch right from the

start providing straight-forward operation.
These effect presets are designed to be added to dry signals. If you move the

STEREO AUX RETURN FX control, you mix the channel signal (dry) and the effect

signal. You can control the balance between the two signals with the channel

fader and the STEREO AUX RETURN FX control.

FX FOOTSW
Connect a standard foot switch to the foot switch connector; use this to switch

the effects processor on and off. A dot at the bottom of the display indicates if the

effects processor is muted via the foot switch.

On the following page, you will find an illustration showing how to
connect your foot switch correctly.

LEVEL
The LED level meter on the effects module should display a sufficiently high

level. Take care to ensure that the clip LED only lights up at peak levels. If it is

lit constantly, you are overloading the effects processor and this could cause

unpleasant distortion. The FX control (AUX SEND 2) determines the level that

reaches the effects module.

PROGRAM
You can select the effect preset by turning the PROGRAM control. The display

flashes the number of the current preset. To recall the selected preset, press the

button; the flashing stops. You can also recall the selected preset with the

foot switch.
