USER GUIDE

ROUTING THE CHANNELS TO THE OUTPUTS

Each of the 6 channels may be routed as required to a combination of the 3 outputs

L, R and M to feed up to 3 mono zones or one stereo and one mono zone. The L

and R post level outputs may also be routed to the M output for situations where a

L+R sum is required. Note that the channel inputs may be summed with L+R to

provide an independent mix based on the L and R outputs.

OPTION LINKS - CHANNEL ROUTING

Select the inner jumper links for routed signals, outer links for not routed.

MAIN OUTPUTS

The main L, R and M outputs are available on electroni-

cally balanced line level 3-pin XLR male connectors.

OPTION LINKS - LINE OUTPUT LEVEL

These may be individually set for one of three standard

operating levels by positioning the jumper links as

shown. +4dBu (1.2Vrms) High level

0dBu (0.775Vrms) Line level

-10dBV (300mVrms) Low level

OPTION LINKS - OUTPUT XLR GROUND LIFT

Set the jumper as shown to connect or disable XLR pin

1 from audio 0V for optimum system grounding to avoid

problems with ground loops.

L,R,M SYS-LINK INPUTS/OUTPUTS

The L, R and M outputs are also available on the SYS-LINK

OUT connector. Inputs are available on the SYS-LINK IN

connector. These operate unbalanced at -2dBu (600mVrms)

and may be used as additional mix inputs and outputs or to

expand the system using SYS-LINK.
