Front Panel Controls and Operation
1. Aux Input: A standard 1/8” mini stereo jack to plug in an external sound source (iPod, MP3
player, etc.). The Aux Input does not go to the DI. Maximum, unclipped input level is 2Vrms.
2. Aux Gain: Gain control for the Aux input device. Adjust this knob to achieve the desired
level of your Aux Input source and to obtain the relative balance between this source and your
instrument. If the OL indicator illuminates, turn down Aux Gain level on B
|
AMP until it no
longer flashes. If it still flashes with level all the way down, turn level down from device
connected to Aux input and then readjust Aux Gain level.
3. Input: A 1/4” unbalanced input jack to plug in an active or passive bass into a studio quality,
high impedance, input buffer.
4. Input Gain: Gain control for the Instrument input. Adjust this level to obtain maximum input
gain before any flashing of the OL indicator occurs.
5. OL (overload) Indicator: Indicates the input stage of the B
|
AMP is being overdriven when
flashing yellow. If an overload condition is indicated, turn appropriate gain knob (Aux or Input)
counterclockwise to reduce gain until no flashing occurs and adjust Master volume to achieve
desired volume. Also learn more about properly adjusting the Input gain of the B|AMP in the
Instrument Level section of the Program Mode part of this manual.
6. Master (volume): This control raises and lowers the Master volume of the B
|
AMP.
7. Protect (indicator): Should the amp experience a fault (over heat, over current) the amp
will mute the output and this LED will turn red until the condition is corrected. Check and make
sure there are no obvious conditions causing the amp to enter protect mode such as a shorted
speaker cable or the fan or vent holes being blocked on the outside of the unit.
