4 A Tour of the GRIP

Rear Panel

INPUT Jacks

The GRIP’s two input jacks give you analog stereo inputs using TRS balanced 1/4” connectors. If you are using a mono instrument, plug it into the left input jack.

The nominal input level, with the INPUT knob at 12 o’clock, is +4 dBu (1.23 VRMS). Input impedance is 10 kOhms.

OUTPUT Jacks

These two jacks provide analog stereo output using TRS impedance-balanced 1/4” connectors. These outputs carry the total signal from the GRIP, including the sub-harmonic synthesizer’s channel. If you want to output a mono signal, use either jack.

The nominal output level is +4 dBu (1.23 VRMS) = -15 dBFS, and the maximum output level is +19 dBu (6.9 VRMS) = -0 dBFS. Output impedance is 150 Ohms.

XOVER OUTPUT Jack

This jack carries the combined bass and sub-bass signals – as determined by the XOVER Frequency and LO CUT Frequency knobs.. This jack is a TRS impedance-balanced 1/4” connector, and has the same maximum output, nominal output and impedance as the OUTPUT jacks.

IEC POWER Jack

Here’s where you plug in the GRIP’s IEC power cord. This jack is made to accept most IEC power cords. It has a universal input of 100 – 260 VAC.
