1.GENERAL. The amplifier shall have a free-standing frame with front and rear brackets for rack-mounting, and supplied with four resil- ient feet suitable for table- top placement. The amplifier shall be capable of two- channel operation, with a switch to place the amplifier into single-channel operation by bridging the outputs of the two channels.
2.POWER OUTPUT.M•1200: The power ampli- fier, being of two channels, shall deliver 225 watts RMS into 8 ohms per channel, 400 watts into 4 ohms, and 600 watts into 2 ohms with both channels operating. In bridge-mode of operation it shall deliver 800 watts RMS into 8 ohms and 1200 watts into 4 ohms.
M•1400: The power ampli- fier, being of two channels, shall deliver 250 watts RMS into 8 ohms per channel, 425 watts into 4 ohms, and 630 watts into 2 ohms with both channels operating. In bridge-mode of operation it shall deliver 850 watts RMS
into 8 ohms and 1260 watts into 4 ohms.3.POWER SUPPLIES. All necessary operating voltages for the amplifier shall be pro- vided by an internal power supply. A master power switch shall be located on the front panel along with a green power-indicating light.
4.INPUT CHANNEL CONNECTIONS. Each monaural input channel shall have an electronically balanced line-level input, accommodating a nominal line level between –10dBV and +4dBu, and appearing on the rear panel as a female XLR-3 type connector. In addition, each monaural input channel shall have a parallel 1/4" TRS phone jack and a male XLR-3 type connector, which can be used as inputs or “thru” jacks for daisy-chaining the input signal to another amplifier. Pin 2 of the XLR connectors, and the tip of the 1/4" TRS phone jack, shall be non-inverting.
