CONTROL ELEMENTS:
21
SIGNAL AND CLIP LED
The 4-segment level indicator displays the signal level. The CLIP LED´s illuminate when the output signal is
driven too high, which could cause distortion. If this happens, use the MAIN LEVEL control to reduce the main
level until the LED does not light anymore.
22
FX
The FX SEND controls of the stereo channels function similar to those of the mono channels. However, since the
FX send buses are both mono, a mono sum is a first taken from the stereo input before it is sent to the FX bus.
23
FX SEND CONNECTOR
The FX SEND connector outputs the signal you choose from each individual channel using the FX SEND controls.
You can connect this to the input of an external effects device order to process the FX bus master signal. Once
an effects mix is created, the processed signal can then be routed from the effects devices outputs back into a
STEREO LINE INPUT or the STEREO AUX RETURN (only LAX 602).
24
STEREO AUX RETURN (ONLY LAX 602)
The STEREO AUX RETURN connectors are used to bring the output of the external effects device (whose input is
derived from the aux sends) back into the console. You can instead use these connectors as additional inputs,
but any effects device will then have to be brought back into the console via a normal stereo channel. This does,
however, give you the ability to use the channel EQ on the effects return signal if you wish.
-When you are using a stereo channel as effects return path, the FX control of the relevant channel should
generally be turned fully down to avoid undesirable feedback.
25
STEREO AUX RETURN CONTROL (ONLY LAX 602)
Use the AUX RETURN control to determine how much of the effects signal is sent to the main mix. If only the left
connector is used, the AUX RETURN automatically operates in mono.
26
CONTROL ROOM OUT
The unbalanced CTRL ROOM OUT connector carry the summed effects and main mix signals. The PHONE/CON-
TROL ROOM control adjusts the level of both headphones and CONTROL ROOM OUTPUTS.
27
FX TO CTRL
If you want to monitor only the FX send signal in your headphones or monitor speaker(s), press the FX TO
CONTROL ROOM switch.
28
LOW CUT
In addition, the mono channels are equipped with a steep LOW CUT filter designed to eliminate unwanted low-
frequency signal components. These can be noise created by hand-held microphones, subsonic noise or plosive
sounds created by highly sensitive microphones.
29
SENSITIVITY +4 / -10
The stereo inputs have an input sensitivity switch which selects between +4 dBu and -10 dBv. At -10 dBV
(home-recording level), the input is more sensitive (requires less level to drive it) than at +4 dBu (studio level).
