REAR PANEL

INPUT 2 SECTION

INPUT 2 JACK

1/4-inch, 4.7megOhm. This high impedance input is designed with piezo pickups in mind to provide maximum output and dynamics. Plugging into Input 2 lets you match the SansAmp PSA’s input cir- cuitry to the signal level being fed into it, assuring the best signal-to-noise ratio and least distortion.

This input is ideal for rack and patch-bay applications, especially if you use other signal processors or multi-track recorders before the SansAmp PSA. Note: When you plug into the front panel Input, the rear panel Input 2 is disconnected. Also, you can set the Input Level Selector Switch to its 0dB position when you plug in extra-hot signals, such as the output from active bass guitars.

LEVEL SELECTOR SWITCH

This switch lets you connect the SansAmp PSA to a wide variety of equipment with a variety of signal levels. It has two positions:

0dB position. This engages the input pad. Set the switch in this position when sending a line-level signal into the SansAmp PSA. When the switch is in this position, the signal coming into the unit is padded down by 10dB.

-10dB position. When the input pad switch is disengaged (at its -10dB setting), the rear panel Input 2 is optimized to receive an instrument level signal. In this position, Input 2’s sensitivity is exactly the same as the front panel’s Input.

EFFECTS LOOP

EFFECTS SEND

Sends the SansAmp PSA’s signal to processors. When nothing is plugged into the Effects Loop, the signal passes through from the SansAmp PSA to the Output jacks, with both left and right Output jacks receiving the same signal. Note: Effects Loop Send is muted in bypass programs.

MIX 50/50 SWITCH

The 1/4" Send routes 100% of the SansAmp PSA’s signal through your effects processor when the 50/50 switch is disengaged. If you engage the 50/50 switch, then 50% of the SansAmp PSA signal goes through your effects processor, and the other 50% passes directly to the 1/4" and XLR Outputs.

To preserve the signal integrity of the SansAmp PSA, use the Effects Loop with the 50/50 switch engaged. When the SansAmp PSA is in this mode, the effects processor’s mix control should be set at 100% wet. Your relative wet/dry mixture can then be controlled by increasing or decreasing the effects processor’s output level.

RIGHT RETURN

When using a mono effects processor, plug the processor’s output into the SansAmp PSA’s Right Return. This will route the signal to both pairs of left and right Outputs.

LEFT RETURN

This is one of two stereo returns for the Effects Loop. If your signal processor has only one out- put (mono), then plug it into the Right Return.

UNIVERSAL OUTPUT SECTION

Another aspect of the technological advancement of the SansAmp PSA is that its output sections are physically compatible with any application. The outputs can be used for full range (multi-track recorders, studio monitors, P.A. systems) as well as limited range systems (guitar or bass speaker cabinets). Note: You can compensate for different frequency responses of speaker enclosures by using the High control.

1/4" OUTPUT JACKS

These left and right 1/4" jacks carry the signal from the SansAmp PSA. This includes any effects that are placed in the Effects Loop. The Output level switch (0dB/-10dB) lets you inter- face the SansAmp PSA with a variety of line and instrument level inputs, including recorders and mixers requiring low-level signals, signal processors, and power amps.

1/4" OUTPUT LEVEL SWITCH

Selects the Output level’s range. When in its 0dB position (engaged), the Output is at line level. When the switch is in -10dB position (disengaged), the Output is at instrument level.

XLR OUTPUT JACKS

The SansAmp PSA’s two XLR Outputs are designed without transformers to provide a low- impedance output of extremely high quality for recording or interface with professional-quality signal processors. (It includes any effects that are placed in the Effects Loop.) XLR and 1/4" Outputs may be used simultaneously. Minimum output impedance is 600 Ohms.

XLR OUTPUT LEVEL SWITCH

Sets the range of the signal level sent out of the XLR Output jacks. When in the 0dB position (engaged), the Output is in the line level range. When the switch is in its -10dB position (disengaged), the Output is in the instrument level range.

Note: The standard output level range of the SansAmp PSA is 0dB due to the wide availability of digital recorders, which are unforgiving to excessive input levels. This prevents overloading the input of a digital recorder.
