AC Input receptacle Inputs and Outputs (channels A-D) This is a standard 3-prong IEC power connector. Connect the supplied detachable linecord to this power receptacle, and plug the other end of the linecord into an AC outlet. The internal universal power supply can accept any AC voltage from 100 VAC to 240 VAC. It will work virtually anywhere in the world, so that's why we call it a "Planet-Earth" power supply! The power supply is less susceptible to voltage sags or spikes than conventional supplies, providing greater electromagnetic isolation and better protection against AC line noise. 2. POWER switch Press the top edge of this rocker switch in to turn on the Quad Comp/Gate. Turn it off by pressing the bottom edge of the rocker switch. 3. SIDE CHAIN SEND These 1/4" TRS jacks output the channel signals after the gate section, and before the compressor. These can be connected to an external EQ or processor, and then back to the RETURN [4] of the same channel or a different channel for triggering of the compressor. They can accept balanced TRS plugs, or unbalanced 1/4" TS plugs, tip hot. The IN and OUT jacks will pass through signals if the power is not applied to the Quad Comp/Gate. For example, if your mixer's left main output is coming into the Quad Comp/ Gate channel-A input, the same signal will appear at the channel-A output jack if the Quad Comp/Gate is off. These inputs and outputs are line-level, and you would normally connect them to a mixer or line-level component in your system. For example (OK, a bad example), do not connect microphones or instruments directly to the inputs. 5. TRS Inputs and 6. XLR inputs These 1/4" TRS (tip-ring-sleeve) jacks are the inputs for the channels. They can accept balanced TRS plugs, or unbalanced 1/4" TS (tip-sleeve) plugs, tip hot. The female XLR jacks are also the inputs for the channels (pin 2 hot, pin 3 cold, pin 1 shield). For each channel, the XLR and TRS inputs are in parallel, so you can choose either style as an input. You can use unbalanced TS connections, but we recommend using balanced connections wherever possible. 7. TRS Outputs and 8. XLR Outputs These 1/4" TRS jacks are the outputs for the channels. They can accept balanced TRS plugs, or unbalanced 1/4" TS plugs, tip hot. 4. SIDE CHAIN RETURN The male XLR jacks are also the outputs for the channels. These 1/4" TRS jacks are used as inputs to the compressor's sidechain input. Any signals coming in here will be used to trigger the compression of that channel. (The signals are not going into the compressor's audio path, just its detector and leveling circuits.) For each channel, the balanced XLR and TRS outputs are in parallel, so you can choose either style of output. Both TRS and XLR outputs can be driven simultaneously. They can accept balanced TRS plugs, or unbalanced 1/4" TS plugs, tip hot. 10 QUAD COMP/GATE
