Balanced XLR OUT

REAR PANEL FEATURES

The Balanced XLR out is a true electronically balanced record out. The signal appearing at the XLR out is governed by the position of the Line/Direct switch. In the LINE position, all front panel controls are functional except the Master Volume, and the signal is essentially the same as that heard through your speaker system. The output level in the Line position is adjusted by the GAIN control on the front panel. If you are using an effect, this will also appear mixed in the signal when you are in the line mode.

In the DIRECT position, the Balanced XLR out becomes an active TUBE direct box. No front panel controls are functional and the level is only adjustable via your instrument.

Wiring for the XLR connector is as follows:

Pin 1 = ground, Pin 2 = +, Pin 3 = – (minus) (American Standard)

LINE/DIRECT SWITCH

The Line/Direct switch gives the user the option of either a line signal (preamp out) or direct sig- nal from the instrument. The signal appearing at the XLR out is slightly “hotter” than normal DIs. You may want to inform the live soundperson or recording engineer of this.

To use the Line/Direct function, position the knob in the desired location. Make sure the switch is all the way to the left or right to avoid an intermittent condition.

Note: Turn off transients appear at the record outs when the amplifier is shut down. It is recommended that equipment being used in conjunction with the record out be turned down, off, or disconnected BEFORE the Bass 350 is turned off.

TO TUNER INPUT

The To Tuner input allows the user to plug an instrument tuner into this jack and tune up without having to unplug and go back and forth from amp to tuner. This feature is totally isolated from the rest of the preamp and will function regardless of the settings on the front panel. Being isolated on a side chain avoids loading down of the instrument, which can cause a loss in dynamic range.

To use this feature, connect a shielded patch cord from the To Tuner input to the input jack on your tuner. Turn the amplifier on and you're ready to go. If you do not wish to monitor your sound during the tuning process, you may turn down the Master Volume.

EFFECTS LOOP

The Effects Loop is used in conjunction with the Effects Blend control on the front panel. When the Effects Blend Control is in the full counter-clockwise (dry) position, no effects will be heard. The Effects Loop is compatible with most individual or multi-effect effect units. It is designed as a “side chain” function and works exactly like those found on studio consoles. Many effects on the market have input level adjustments. For instance, some units have a switch that you can set for either –10 dB or +4 dB. In all cases, these should be set for 0 dB (if available) or +4 dB. The level going to your effect is controlled by the Gain control on the Bass 350’s front panel.

Use of the effects loop should greatly reduce the noise generated by effects units (as compared to using the effect between your instrument and the input jack). This is because the loop is after the preamp gain stages.
