Selecting Stereo, Parallel, or Bridge Mode

The amplifier can be set for normal Stereo mode, Parallel Input mode, or Bridge Mono mode.

Stereo Mode- Each channel remains inde- pendent, and may be used for two different signals.

Parallel Mode - This setting connects both inputs together. One signal feeds both channels. Each channel's Gain control and speaker connection remain independent.

Bridge Mode- This setting combines both channels of a pair into a single channel with twice the output voltage. Use only the first channel's input and Gain control. Set the second channel's Gain control at mini- mum. The load must be rated for the higher power (or voltage) and is connected as shown on pages 6 and 7.

Do not connect more than one input when operating in parallel or bridge mode.

Setting Low Frequency Filters

ISA 280, ISA 450, ISA 750 and ISA 1350: Use of the Low Frequency Filters is recom- mended. Use the appropriate switch set- tings to turn the filter ON or OFF and to select the filter frequency. When set to the ON position, the channel has a 12dB per octave Low Frequency filter to limit subau- dio cone movement, making more power available for the loudspeaker’s rated fre- quency range. The filter should only be turned OFF for driving subwoofers.

ISA 300Ti, ISA 500Ti, and ISA 800Ti: The Low Frequency Filters are always active and not defeatable. Each channel has a 12dB per octave Low Frequency filter to prevent saturation of the 70V loudspeaker transformers. This reduces distortion and prevents amplifier overload. The 50 Hz set- ting usually works well with high quality loudspeaker transformers. The 75 Hz set- ting works well with speech-grade loud- speakers and transformers.
