Specifications
LB2 Dual Group Module
The Dual Group Module is provided with XLRs on a 4 group console and
¼ jacks on a 8 group console, insert send and returns. Clean feed outputs
are provided on XLRs on an 8 group console and jacks on a 4 group console.
1. Signal is sent to Aux 1-4 buses via the four level controls. The Auxs have
unity gain when the controls are fully clockwise. The source signal is fed
from pre or post group faders. The pre or post switch operates on all four
Auxs.
2. The other four Auxiliaries are fed from the other group (Right) fader.
Each Dual Group module contains one clean-feed master therefore the
amount of clean-feed buses is dependent on the amount of Dual Group
modules fitted.
3. The Level control adjusts the level of the balanced Clean-Feed output
which is fed from the selected clean-feed input module. Jumpers make the
clean-feed bus selection of which positions are used to source on the 14
position motherboard. Therefore if the signal is inserted into the first of the
input modules (clean-feed 1) it will then be removed from the clean-feed
output 1 on the group module.
4. The Talk Enable switch provides signal from the Comms system to be fed
to the clean-feed outputs when the Comms system is activated.
5. The clean-feed Mute switch cuts off the signal to the clean-feed outputs.
6. The clean-feed AFL switch provides the post level signal to the monitor
speakers replacing the selected source.
7. Signal is sent to the Aux1&2busviatheAux Level control
(optionally Aux3&4using the internal jumpers). All the Auxs have unity
gain when the controls are fully clockwise and are switched pre or post in
pairs by the PRE switches. The source is fed from the Group Return.
8. The Stereo Return Level control adjusts the level of the return signal.
Gain of +10dB of gain is provided when the control is fully clockwise.
9. The ST/Mix Group switch determines whether the output can be sent to
the Stereo Bus or the associated pair of groups.
10. The Pan control feeds the signal to the Stereo mix or the groups.
In the centre there is a drop of -3dB.
11. The Return Mute switch cuts of the signal from the Stereo bus or the
group bus. Also mutes the PFL and aux pre and post.
12. The Return PFL switch provides Pre Fade signal to the monitor speakers
replacing the selected source.
13. The ST Assign switch assigns the signal to the Stereo bus.
The source signal is from the group output fader.
14. The Pan control feeds the signal to the Stereo bus and to the Stereo AFL
bus. In the centre there is a drop of -3dB.
15. The Mute switch cuts off all output from the channel and utilises a soft
mute for click free switching.
