2 Installation

Always remove power from the unit and turn the level controls off (fully counterclockwise) when making or breaking connections. This reduces the chance of blasts that can cause loudspeaker damage.

The guidelines below are provided to help you quickly get your amplifier installed and ready to go. Be sure to follow the instructions in Sections 2.1 and 2.2 for the selected mode of operation. Additional information on input sensitivity, load protection and required AC mains is provided in Sections 2.3, 2.4 and 2.5.

1.Install the amplifier in a standard 19 inch (48.3 cm) rack or place it on a stable surface. The mounting dimensions are 19 inches (48.3 cm) wide, 3.5 inches (8.9 cm) tall and 16 inches (40.6 cm) deep behind the mounting sur- face. IMPORTANT! Allow for adequate ventilation.

2.Use high-quality loudspeaker cables to connect the load to the amplifier’s outputs. Do not use shielded cable.

3.Use shielded cables to connect audio sources to the amplifier inputs. Either balanced or unbalanced wiring can be used as shown below. (XLR connectors are avail- able with the MT-XLR accessory. See Section 5.)

2.1 Stereo

1.Turn down the level controls (fully counterclockwise) and turn off the amplifier.

2.Set the back panel stereo/mono switch to Stereo.

3.If present, remove the Parallel-Mono jumper.

4.Connect the input and output cables as shown in the first example in Figure 2.1.

5.Turn on the amplifier and adjust the level for each chan- nel using the back panel level controls.

CAUTION: Never parallel the two outputs by di- rectly tying them together, and never parallel them with the output of another amplifier.

2.2 Mono

Your amplifier’s mono modes provide double the power of Stereo mode in a single channel. In Bridge- Mono mode, the outputs are wired in series for twice the output voltage. In Parallel-Mono mode, the outputs are paralleled for twice the current capacity.

Bridge-Mono mode is provided for loads with an im- pedance greater than 4 ohms. Parallel-Mono mode should be used with loads of 4 ohms or less.

B R I D G E - M O N O

1.Turn down the level controls (fully counterclockwise) and turn off the amplifier.

2.Set the back panel stereo/mono switch to Bridge-Mono.

3.If present, remove the Parallel-Mono jumper.

4.Connect the input and output cables as shown in the sec- ond example in Figure 2.1. Only use the channel 1 input.

5.Make sure the load is balanced (neither side shorted to ground) and do not use the black (–) binding posts.

6.Turn on the amplifier and adjust the level. Only use the channel 1 level control.

1.

Turn down the level controls (fully counterclockwise) and

 

turn off the amplifier.

2.

Set the back panel stereo/mono switch to Parallel-Mono.
