® 2 • 12-11-10-9-8-7-6 Output Flexibility. Each of the 12 amplifiers can be driven singly or bridged to allow several channel and power output capabilities. It can be configured into seven power packages as follows: - Twelve 35-watt amplifiers - 12 total.
® 3 Amplifiers & Preamplifiers In addition, this switch must be left in the MANUAL OFF (OUT) position to permit an external DC Control Voltage to power the PA1235 ON and OFF. Refer to " REMOTE MASTER ON/OFF CONTROL " terminals, item #13.
® 4 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).
® 5 Amplifiers & Preamplifiers 12. SPEAKER Terminals. These plug-in 4-terminal screw type connectors permit speaker wire sizes up to 12 gauge.
® 6 • 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.
® 7 Amplifiers & Preamplifiers 7. MUTE ON / OFF . Separate ON / OFF Mute commands give positive mute action without knowing the actual mute status. This is very helpful in a remote room where commands are sent “ blind ” without any visual aids for status.
® 8 2. If mounted in an equipment cabinet or other confining location, allow at least 2 inches of space above the top cover (see Fig. 4 ). Be sure there are large openings in the shelf below the unit and in the cabinet to allow the entry of cool air and the escape of warm air.
® 9 Amplifiers & Preamplifiers 6. As a rule of thumb, use 18 gauge speaker wire for speaker runs up to 30' (9m), 16 gauge up to 70' (21m), and 14 gauge up to 150' (39m). The 4-terminal connectors accept wire sizes up to 12 gauge max.
® 10 NOTE: Only one speaker is connected per amplifier pair in the BRIDGED mode! CAUTION: When operating in the BRIDGED mode (particularly when bench testing the amplifier) do not make a ground or any other kind of connection to the amplifier speaker terminals other than those to the individual speakers as shown.
