1. INPUT — Connect the signal source to this 1/4" unbalanced TS jack.

2. INST/AMP — Leave this switch out when connecting an instrument

or line-level signal to the INPUT jack. Push this switch in when connecting a speaker-level signal (for example, from a guitar ampliﬁer’s speaker output).

3. FLAT/FILTER — Push this switch in to engage a high-cut ﬁlter to reduce hiss and noise when using the AMP input setting. The ﬁlter has no eﬀect when the input is set to INST (2).

4. THRU — This 1/4" unbalanced TS jack is in parallel with the INPUT jack and provides a “Thru” connection of the input signal for sending to an ampliﬁer onstage.

It is important to keep your receipt in a safe place, and not a bad idea to write your product information

here for future reference (i.e., insurance claims, tech support, return authorization, etc.).

5. OUTPUT — This balanced XLR jack provides a low-impedance miclevel signal for connecting to a microphone input on a mixer. Pin 1 = Ground

Pin 2 = Hot (+) and in-phase with the input signal Pin 3 = Cold (–)

6. GND/LIFT — This switch makes or breaks the input ground to pin 1 of the XLR output jack. When the switch is in the OUT position, the ground is connected, and when the switch is pushed IN, the ground is disconnected (LIFTED).
