User manual RANE GM 16

[. . . ] GM 16 Instructions DESCRIPTION Amplifying the acoustic sound of an instrument over a sound system has been difficult. [. . . ] This jack replaces the existing jack or endpin on the instrument body. If a ¼" TRS cable is used, both pickup and mic signals are kept separate on a single stereo cable. Enlarge the hole for the GM 16 with a ½" tapered reamer if needed. If the instument has a pickup, disconnect the wires from the existing jack and solder those leads to the loose set of wires protruding from the middle of the GM 16. Insert the microphone assembly through the soundhole and tighten the strap button/ locknut from outside the instrument. Connect a quality ¼" TRS to TRS cable from the instrument to the preamp. MICROPHONE PLACEMENT Position the microphone approximately ¼" beneath the soundboard near the treble side of the soundhole, with the active black face of the microphone towards the interior of the instrument (approximately towards the chest of the player). Rotating the active face of the mic towards the back of the guitar often tends to reduce excessive bass response.
