• Since it includes adjustable code groups, the user may inadvertently alter the installer configurations.
• Also, since the user will require IR commands from other brands of equipment to control the total system,
in addition to those of the PA1235, all commands should be consolidated into one learning device, for
ease of use.
APPLICABLE RC68+ BUTTON DESCRIPTIONS
1. IR Emitter Lens.
2. Instant Volume Presets. These commands allow ran-
dom access or direct preset activation of any of 12 fixed
preset levels on the PA1235. This is useful when setting
up "audio scene" ambiance levels for rooms or partial
mute actions.
The RC68+ buttons that select a fixed level attenuation
below Max. volume are as follows:
RC68+ Button PA1235 Level Attenuation in dB
38 (Mute ON) > 90 (Min. Volume)
10 (C & 01 on RC68) 60
00 (1) 52
C0 (2) 44
50 (3) 36
D0 (4) 30
40 (5) 24
A0 (6) 18
30 (7) 14
B0 (8) 10
20 (Treble Up Arrow) 6
E0 (Bass Up Arrow) 0 (Max. Volume)
3. OFF Command. Turns the amplifier pairs (both LOCAL
and COMMON) to Standby OFF mode. The "Standby
OFF" mode remains until the MUTE OFF command is
sent.
NOTE: This command is inhibited automatically when
the CI terminal is driven high with an external control
voltage. Refer also to items 9 and 11, Fig. 3.
4. C-BAL Command. Instantly returns the balance to the Center position (equal volume in each channel)
from any previous setting.
5. Balance Commands. When the Balance "arrow" buttons are pressed, the audio output will move to
the left or right (with a 2 dB/step reduction in the attenuated channel) with each left or right press.
NOTE:
These commands do not ramp. That is, no change will occur if the BALANCE buttons
are held down continuously!
6. MAX-V. This command saves a maximum desired volume level for a zone or rooms (both LOCAL and
COMMON). The volume is first adjusted to what is desired as a maximum level. The MAX-V button
is then pressed, locking in this setting. This acts as a volume limiter for the system (e.g. to prevent
the kids from over-driving wall speakers, etc.).
To unlock the MAX-V setting, press the ADJ-OFF button (item #10).
