Trigger Out Connection

The Trigger Out jack lets you loop or “daisy-chain” the trigger voltage to additional amplifiers or other components.

Audio Trigger Sensitivity Adjustment

The Auto On Audio Sensitivity Control adjusts the audio signal level threshold to turn on the Zamp v.2. It adjusts the audio trigger sensitivity from 30 mV (fully clockwise) to 2 V (fully counterclockwise). The center position corresponds to 50 mV, which is suitable in most cases.

Ground Lift Switch

The Ground Lift Switch isolates the circuit ground from chassis ground. This often helps eliminate hum that results from ground loops caused by multiple ground paths such as metal-to-metal contact with other components in an equipment rack plus the ground of the AC cord. If you experience hum in the system, try moving the Ground Lift Switch to its Lift position.

AC Power Connections and AC Grounding

If possible, plug your Zamp v.2 into the same AC outlet that powers your accompanying audio components and especially the system controller. If you use a different AC outlet, you may encounter AC hum caused by its differing ground potential.

Operating the Zamp v.2

On-Off Button

Manual Turn On

Press the On-Off button once to turn the unit on, press it again to turn the unit off.

Automatic Turn On

Your Zamp v.2 can be turned on automatically. See Automatic Turn On Options for details about automatic triggering.

Level Controls

Each channel has an input level knob so you can adjust the input sensitivity of the Zamp v.2 for the best signal-to-noise ratio with your preamplifier or system controller. If there is no increase in background noise, we recommend setting both Level controls fully clockwise.

Front Panel Indicators

AC Line

The amber AC Line indicator lights whenever the unit is plugged into a live AC source.

On

The On indicator lights green when the Zamp v.2 is on.
