sPeAKeR OUT
The STUDIO PRE 500 can be connected to a speaker cabinets using either 1⁄4” speaker cables (do not use instrument cables) or speakon speaker cables. When using two cabinets, simply connect the second cabinet
to the first cabinet. The high-quality Neutrik SPEAKON COMBO jack (26) is designed to accept either of these connection types. The STUDIO PRE 500 delivers 300W of power into an 8 ohm cabinet, or 500W into a 4
ohm cabinet (or two 8 ohm cabinets).
AmP CHANNel OUT
This balanced XLR (27) output allows you to send the AMP CHANNEL directly to a mixing console (either in recording or live situations) or soundcard (with XLR inputs) without the need of a DI box. Simply connect a
standard XLR cable from this output to the soundboard/mixing console, or a snake connected to the board/console, or a soundcard XLR input. If the engineer needs more or less signal from the AMP SECTION, simply
turn the front panel AMP OUT LEVEL (21) control up or down as necessary.
CleAN CHANNel OUT
This balanced XLR (28) output allows you to send the CLEAN CHANNEL directly to a mixing console (either in recording or live situations) or soundcard (with XLR inputs) without the need of a DI box. Simply connect
a standard XLR cable from this output to the soundboard/mixing console, or a snake connected to the board/console, or a soundcard XLR input. If the engineer needs more or less signal from the CLEAN SECTION,
simply turn the front panel CLEAN OUT LEVEL (20) control up or down as necessary.
gROUND lIfT AmP
Occasionally when using the AMP LINE OUT (27), the engineer will detect a hum from your signal. This is almost always due to a grounding problem related to your power source; you will likely eliminate this hum
simply by flipping the GROUND LIFT AMP (29) switch.
gROUND lIfT CleAN
Occasionally when using the CLEAN LINE OUT (28), the engineer will detect a hum from your signal. This is almost always due to a grounding problem related to your power source; you will likely eliminate this hum
simply by flipping the GROUND LIFT CLEAN (30) switch.
TUNeR OUT
The TUNER OUT (31) is an unbalanced signal that can be sent to a tuner, allowing you to tune as you play without passing your signal through pedals, which can degrade the quality of your signal.
