Controls And Fu n c t i o n s 1. CIRCUIT BREAKER. This protection device will trip if the line current exceeds the rating of the circuit breaker, causing the amplifier to shut down completely. This operates the same as a standard line fuse, except that it is resettable from the front panel after cooling down for a few seconds.

10 11 8b.CH1 / CH2 INPUT CONNECTORS. 6 position barrier strip. Horizontal connection accepts 8mm spades. (see page 10 for more information). 9. FUTURE OPTION. Knockout for connector (TRS232) for external computer monitoring. 10. SIGNAL SMART THRESHOLD CONTROL. Sets desired signal level for activation of Standby circuit. (See page 12 for more information) 11.
Mechanical Considerations The PX850 and PX1450 require three rack space units (5.25”) and a depth of 15.38” inside the rack, including the rear supports. Secure the unit mechanically using four screws with washers to prevent marring the front panel. Neoprene rubber washers are a good choice because they grip the screw head and prevent them from backing out when vibrated or transported.
For balanced operation: 1/4-inch phone jack: Use a 3-conductor TRS (tip-ring-sleeve) 1/4” phone plug. The tip of the plug carries the “+” (high, noninverting) side of the signal, the ring carries the “-” (low, inverting) side of the signal and the sleeve is ground (see Figure A ) .
Output Wi r i n g (See page 17 for recommended Carver Professional A c c e s s o r i e s) . Use heavy gauge cable for speaker connections. The greater the distance between the amplifier and the speakers, the larger the diameter the cable should be to minimize power losses across the cable and improve the damping of the speaker.
The PX1450 has sufficient output voltage capability in stereo mode to drive 70-volt distribution systems without using a step-up transformer at the amplifier. In this configuration, the PX1450 delivers up to 375 watts per channel to the 70-volt system, depending on the impedance of the total system. A s with all 70-volt systems, transformers are still required at each loudspeaker.
CareandServiceAssistance C a re: Wipe off the PX850/PX1450’s front panel and chassis from time to time with a soft, dry cloth. If you have something stubborn to remove, use a mild dish soap or detergent sparingly applied to a soft cloth. Don’t use alcohol, ammonia, or other strong solvents.
Note: The Carver P rofessional limited warranty does not extend to damage resulting from the following pro c e d u re if attempted by any person not specifically authorized by Carver P ro f e s s i o n a l To move the gain controls from the front panel to the back panel (or vice versa): 1.Unplug amplifier from power source.
3 .Verify that the total load impedance presented to the amplifier is within the limits described in this manual for the mode of operation selected. Carver Professional reserves the right to improve its products at any time. Therefore, specifications are subject to change without notice. 15locale.
