GETTING STARTED

Set the INPUT VOLTAGE SELECT SWITCH (8) for either ~115V(60Hz) or ~230V(50Hz) AC power. Attach the power cord and plug it in.

Connect the Input and Output signals from the SDR-260 to your audio system with the appropriate XLR balanced or 1/4” unbalanced INPUT and OUTPUT JACKS (11, 13, 14, 16), depending on the type of cable and connectors you’re using. For Mono input use the Left channel input connector. XLR output is disconnected when output 1/4” jack is inserted.

Turn the POWER SWITCH (7) On. You will see the preset Program number [P 1] on the VALUE INDICATOR (3).

ADJUSTING LEVELS

Adjust the INPUT GAIN CONTROL (1) for the highest setting without the red top L/R LED indicators of the INPUT LEVEL DISPLAY (2) staying on continuously. Occasional flickering of these red LED indicators is normal.

The INPUT LEVEL SWITCH (15) and OUTPUT LEVEL SWITCH (12) are provided to adjust the levels for the optimum performance. Adjust the level controls to minimum noise and distortion while operating with the components of your sound system.

MODE SELECTION

Pressing the ROTARY CONTROL KNOB (6) quickly will cycle the modes from “P” Preset programs [P1-P60], to “U” User programs [U1-U60] where custom programs are stored, to finally PAS where the effects are bypassed.
