-MATRIX SETUP the MATRIX SETUP switch puts the matrix module in a
programming mode. In this mode all 24 individual tracks can be assigned to
any of the 6 (L,C,R,Sl,Sr,SB) matrix outputs using the SET switches on each
track.
-PRESET A and PRESET B.
The matrix module can be put in two different pre-programmed setups.
When a setup has been programmed in the MATRIX SETUP mode, this setup
can be stored by pressing either PRESET A or PRESET B. When working
with the module, either PRESET A or PRESET B must be activated.

19.2. ALIGNMENT OF VCA's:
a. Activate all the TRIM pots by activating the TRIM switch and position the
pots in their mid position.
b. Connect a voltmeter between pin 2 and 3 of VCA IC-8
c. Now adjust with the small blue adjustment trimmer pots on PCB 5 the
reading to be 0 volt.
d. Repeat this procedure for IC-30 and all for all other VCA banks.
e. Now the VCA's are controlled by the trimmer pots on the Matrix 4 PCB
f. Now adjust the 4 trimmer pots on matrix 4 PCB (CPU) by adjusting the
trimmer pots on matrix 5, VCA-IC8 and VCA IC30. Measure between pin 2
and 3.
g. Now all VCA's are trimmed for 0 dB unity gain.
h. Now connect a +4dBu signal on the dir/playback output and select via the
frontpanel switches an input (dir or playback) and assign this to an output of J3
Matrix 7 PCB. The input can be trimmed with the trimmer pot near the VCA.
The output should read 0dB with an input of +4dBu balanced.
i. First trim the input level and check whether this signal can be assigned to all
outputs.
j. Check if both inputs (DIR/PLAYBACK) are properly working
k. Check if the meter output has a level of 0 dBu.
l. Check if SOLO works.
m. Check if the VCA leveling works.
n. Repeat this procedure for all 24 inputs.
o. Check if the switches Main to CRM / Matrix to main / and Mono surround
work properly.
p. If there is only signal on Surround Left or Right and the Surround outputs
are set to mono surround the output level should read -6dB.
