User manual FENDER BXR 300R

[. . . ] The "MID" and "MID FREQUENCY" controls allow up to 20 decibels of boost or cut of the mid frequencies from 150 Hz to 4kHz. The rugged 300 Watt power amplifier was designed to give reliable service under all conditions and is equipped with our exclusive DELTACOMPTM adaptive compression system. When DELTACOMPTM engages, it is practically impossible to cause the power amplifiers to clip (distort). [. . . ] (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) DELTACOMPTM: With this button in, DELTACOMPTM is active, in the out position, DELTACOMPTM 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 DELTACOMPTM or LIMITING has occurred, depending which position that the switch is in. The unit may seem louder without DELTACOMPTM since the power amp will be allowed to go into clipping. With DELTACOMPTM 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. REAR PANEL DESCRIPTIONS (L) SPEAKER: Speaker connections are four ohms minimum. The BXR 300 is not designed for speaker impedance lower than 4 ohms total. (M) TWO SPEED FAN: The two speed fan normally runs at low speed, and will automatically go to high speed when things get loud. If you suddenly reduce your level, the fan speed (if high) may take a while to return to low (normal) speed. (N) POWER RATING: This indicates how much power the amplifier can "draw" from the wall socket when the amplifier is at full power (1200VA). The marking directly below indicates what the wall socket Voltage and frequency must be. Incorrect line voltage will damage your amplifier and VOID THE WARRANTY! [. . . ] if you get no sound when the device is in the "IN" mode, you may have the wires to the external device crossed (exchanged) or the device may not be turned on. MECHANICAL OPTIONS For those users who will not be "rack mounting" their BXR 300R we have provided the option of removable rack ears. with the rack ears removed, an optional strap handle kit may be installed. If you should use a handle kit other than FENDER, be sure that the mounting screws protrude no more than 1/2 inch past the mounting plane (underside) of the handle. [. . . ]
