REAR PANEL CONTROLS

1.Fan(S)

Cooling fans with variable speed controls. Air enters the amplifier through vents located on the front alu- minium panel. Do not block the front vents or the fans on the rear panel of the amplifier.

2.Input connectors

Connect the input source to these electronically bal- anced Combo connectors using either XLR or 1/4” TRS plugs. The 1/4” TRS and XLR plug are config- ured: Pin 2 (Tip) - hot, Pin 3 (Ring) - cold, and Pin 1 (Sleeve) – shield/ground. We recommend using bal- anced three-conductor cables. A stereo signal should be connected to both the Channel 1 and Channel 2 input jacks for 2-channel (stereo) operation.

NOTE: Unbalanced two-conductor 1/4” plugs can also be inserted into these input Combo connectors. But using unbalanced connectors may increase noise and hum. See more

information about balanced and unbalanced connections in the CONNECTIONS section later in this manual.

NOTE: For BRIDGED MONO or PARALLEL MONO use the Channel 1 input jack only.

3.LINK connectors

These XLR jacks are used to send a signal to a seper- ate amplifier (chaining). The LINK XLR jacks are con- nected in parallel to the input Combo jacks.

4.HPF (High Pass Filter) switch

Use these slide switches to activate the built-in High Pass filters. The HPF rolls off signals below 50Hz. This improves the bass performance of most full range speakers by reducing uncontrolled and excessive speaker cone motion. Engaging the HPF switch when using full range speakers makes more power avail- able to the speaker’s rated frequency range, leading to higher SPLs.
