FRONT PANEL DESCRIPTIONS
The front panel contains all items necessary for system operation and observation. Please read this section of the manual carefully to make sure you understand all the operational features of your new Fender BXR 300. The Front Panel is similar for both the 300R and 300C.
(A)INPUT: Two inputs are provided; Input 1 - High gain
Input 2 - Low gain
The high gain input (INPUT 1) should be used for most instruments. This input can handle as much as 3.5 volts R.M.S., while the low gain input (INPUT 2) accepts 7 volts R.M.S. without audible distortion. For both cases this is greater than any active bass with a 9 volt battery can produce. if you are using a bass with dual 9 volt batteries, or a "hot" passive bass it might be wise to try input 2. For the rare case where two players want to use one amplifier, or where two instruments are to be used during the performance, both inputs may be used.
(B)ENHANCE: HIGH ENHANCE provides high frequency boost. LOW ENHANCE provides low frequency boost, while eliminating
(C)VOLUME: This control sets the gain of the preamp and serves as an adjustment for the "loudness" of the amplifier.
(D)TREBLE: - adjusts the high frequency part of the spectrum. Turning the treble up will cause the sound to become "BRIGHT" or more "CRISP".
(E)MID: - Can be used to add or subtract the frequency range set by MID FREQUENCY control.
(F)MID FREQUENCY: - Adjusts the frequency of boost or cut by the MID control.
(G)BASS - adjusts the low frequency part of spectrum, the area where the "deep" fundamental reside.
(H)PREAMP OUT: The preamp jack is a source of signal as it appears at the power amp input. This jack can be used as a "LINE OUT" or as a "SEND" point for an external effects device.
(I)POWER AMP IN: Use of this jack allows the default input signal from the preamp to be replaced by an external source, (usually the "return" from an effects device).
(J)DELTACOMP™: With this button in, DELTACOMP™ is active, in the out position, DELTACOMP™ is deactivated, and a special ASYMMETRIC LIMITER circuit is enabled. The LED next to this button indicates that the power amplifier has reached full power and that either DELTACOMP™ or LIMITING has occurred, depending which position that the switch is in. The unit may seem louder without DELTACOMP™ since the power amp will be allowed to go into clipping. With DELTACOMP™ on, your volume level will be rather loud before the compressor turns on; this is normal.
(K)POWER: Turns the BXR 300 on or off.
