Note 7 – Zone Balance commands (*CW,30/31):
The Balance-to-Left command increases the left channel by 2-dB, and decreases the right channel by 2-dB. The
Balance-to-Right command is the opposite. For finer control you can adjust only one channel with the *CW,24/25
commands. The left and right volumes may remain at different levels -- the volume up/down and ramping commands
operate on both channels, relative to the volume of each. Balance is maintained when muting/unmuting, and running
volume to the rails and back. After balancing a zone, adjust the volume to the desired level for zone turn-on, and save
the current levels as the Initial-Volume-Levels (balance will be maintained, since left and right initial levels are saved).
Note that the absolute and percent volume commands may be used to overide L/R balance that has been programmed via the
Initial-Volume-Levels, but this is only temporary, as L/R balance will be restored the next time the zone is switched
off and then back on.
Note 8 –Group-Volume/Mute commands (*CW,62/63/64/65/66/67/68/69):
Group commands apply to a group of eight consecutive zones, as defined in the command by gbz and gzd. Parameter gbz is
group-base-zone, and gzd is group-zone-definition, which define a group of up to eight zones. If the group is defined such
that the zones are on different switchers, the returned messages will collide and be garbled – therefore, gbz should be
restricted to 8-zone increments (1, 9, 17…). 4-zone switchers can be used if they are installed on 8-zone increments.
Volume levels are reported for each zone defined in the group.
Each bit in gzd corresponds to one of eight zones, with bit-0 (LSB) being the lowest zone, and the bit-7 (MSB)
being the highest zone. If the bit is 1, the zone is included in the group, and if the bit is 0, it is excluded.
The first zone (selected by bit-0) is defined as group-base-zone gbz. The next seven bits in gzd correspond to the
next seven zones above gbz. For example, if gbz = 9 and gzd = 155, the group includes zones 9, 10, 12, 13, and 16.
First, choose gbz, then to select the appropriate gzd, you need to set the gzd bits corresponding to the desired zones.
Zone gzd-bit bit-value 1=included add bit-values
9 = gbz bit-0 1 1 (lsb) 1
10 bit-1 2 1 2
11 bit-2 4 0 0
12 bit-3 8 1 8
13 bit-4 16 1 16
14 bit-5 32 0 0
15 bit-6 64 0 0
16 bit-7 128 1 (msb) 128
= 10011011 = 155 = gzd
Therefore, when we choose gbz = 9, and set the appropriate bits in gzd to include zones 9, 10, 12, 13, and 16 in
the group, we need gzd = 155. You can get this gzd either by converting the binary value 10011011 to decimal,
or by adding the bit-values that correspond to the included zones (128+16+8+2+1 = 155).
For testing clusters, use the group commands but set gbz to cluster 1 to 8, and gzd to 0.
