2.2.3 EFFECTS LOOP

The Effects Loop jack is designed for use with outboard effects such as
compressors, delay units, or reverbs. A 'Y' cord with one TRS 1⁄4'' connector to
two 1⁄4" TS is required to use this function. This Effects Loop output jack can
also be used to supply the audio feed for a sound card. Most computer sound
cards are provided with a 1/8" (3.5mm) female stereo audio input jack. The
ACOUSTI-Q's signal can be sent to this connection by inserting a 1⁄4" (TS) plug
into the Effects Loop. The Main (XLR) output is defeated if the 1⁄4" jack is fully
inserted. To send a signal to both input channels of the sound card requires the
1/8" stereo plug to have the tip and ring connected to one another.

Tip
If the Main output of the ACOUSTI-Q is to be used to feed a computer's sound
card, this can be done by using a cable with a female XLR connector to a 1/8"
(3.5mm) stereo plug. The correct wiring for this cable is – the shielding from
Pin 1 (GND) of the XLR is connected to the sleeve connection of the 1/8"
stereo plug, the wire from Pin 2 of the XLR is connected to the tip of the
1/8" plug and the wire from Pin 3 of the XLR is lifted (not connected). The
mono output of the ACOUSTI-Q will now be available to the left channel of the
computer's sound card.
