Fig. 3 PA1235 Rear Panel – Features and Functions
8.COMMON AUDIO BUS. A single audio source, such as from a connected preamp, can drive one or more of the amplifier pairs simultaneously, as desired, from this Bus. Any of the amplifier pairs can be switched to the COMMON AUDIO BUS at will by use of the COMMON BUS / LOCAL Switch (see also item #6).
9.LEVEL (System) RESET Button. Pressing this button 2 times within 1 second restores all Factory Default settings. The Factory Defaults for all channels are as follows:
-Input Level set to 1 Volt rms for 35 Watts output.
-Balance centered.
-Mute OFF.
-
-IR Code Group set to A0.
-CI (control in) disabled. Chantes CI control to IR control of Standby ON/OFF. (CI enables when +5 to +30 VDC is applied to CI for 2 or more seconds. See also item #11)
NOTE: The PA1235 will always return to last set values (plus any unaltered factory defaults) after main power shut down or after any power interruptions.
10.FUSE. When required, replace only with a fuse of the same type and rating:
120 V Version: 10 AMP 220 VAC, SLOW BLOW.
240 V Version: 5 A
Replacement with a fuse of higher rating will not protect the amplifier and will void the warranty.
11.IR IN, STATUS, GROUND and CI Terminals. Removable
STATUS Out. Delivers a constant +12 VDC output (9V @ 70 mA) with ON condition. 0 Volts output = OFF (Standby).
GROUND. Ground for IR IN, STATUS out & CI in.
CI = Control Input. Use for control of Standby ON/OFF of amplifier pairs, if desired, instead of by IR. After CI is enabled (see item #9), 0 Volts input = OFF (Standby) condition and +5 to +30 VDC input = ON condition. (12V in draws 16 mA).
NOTE: All
