STUDIO DIMMING RESISTORS

The R-5 STUDIO MUTE circuit is factory set as a 15dB dimming circuit
instead of a muting circuit by the presence of two resistors, R260 and
R261, with a value of 22.1KΩ each. These are shown on the schematic
drawing at coordinates C-3 (p.9-18) and on the OM-5 Output Board
pictorial (p.9-21) at the left edge of the page. To change the circuit to
perform muting instead of dimming, remove R260 for the right Studio
Out and R261 for the left Studio Out. The photo below shows a closeup
of the pertinent section of the board.
Rear view of OM-5 Output Board PCB (detail). The dimming resistors shown must
be removed if you need full muting capability in the Studio Output.
