5.3Link switch

The Link switches located on the rear panel (between the four XLR input connectors) are for changing the operating modes of the amplifier. By using a combination of these switches and input /output wiring it is possible to have several operating configurations. (See below, section 5.2).

the respective channels levels.

Never connect either output terminal to ground or in parallel. The recommended minimum impedance, for quad or tandem stereo operation, is 2 ohms per channel.

5.4.2Notes for amplifier testing

!NOTE: Channels B and D are always polarity reversed on the input, and polarity reversed back on the output. On channels B and D outputs, the positive output voltage with respect to 0V

appears on pin -2 of the Speakon connector. Channel A and C outputs are connected with normal polarity. By having channel A and B (and C and D) operating in opposite polarity, the energy storage in the power supply is more efficient. This is significant for signals below 100 Hz (sub bass etc.) and improves the power bandwidth. Be sure to use balanced inputs on all measurement equipment (including oscilloscope probes) if you are bench testing.
