User manual PEAVEY B-QUAD 5

[. . . ] POWER STATUS LAMP This indicator illuminates when mains power is being supplied to the amp. mASTER VOLUME This control sets the overall volume level of the amp. Once the desired balance between the three channels in the amplifier has been achieved, the entire output level of the unit can be increased or decreased by rotating this control. BOTTOM This control, on both the Ultra and Crunch channels, varies the low frequency response of the amplifier. [. . . ] see the FOOTSWITCH section of this manual for explanation of switch operation. BIAS TEST TERMINALS These terminals are provided to measure the bias of the amplifier's power tubes. A knob behind the back panel grill allows for adjustment. Bias adjustment should only be done by a qualified technician. A high damping factor (TIGHT) reduces cone vibration quicker than a low (LOOSE) factor. This switch works much like the resonance and presence controls on other Peavey amps, if those controls were turned simultaneously. If two enclosures of equal impedance are used, the switch should be set to half the individual value. For example, two 16-Ohm enclosures necessitate an 8-Ohm setting, while two 8-Ohm enclosures would require a 4-Ohm setting. The CABINET IMPEDANCE SWITCH (23) should be set to match the load of the speaker cabinet(s). LINE OUT LEVEL This control sets the level of signal being sent out of the LINE OUT (26) jack. It may be used to balance the level of slave power amp/speaker systems driven from the LINE OUT (26) to the level of cabinets driven from the SPEAKER OUTPUTS (24). Understand the unit's functions, please study the block diagram carefully. 1V RMS-10 V RMS Remote Footswitch: Special 3-button unit with LED indicators (supplied) System Hum and Noise @ Nominal Level: (Clean channel, 20 Hz to 20 kHz unweighted) Greater than 74 dB below rated power (Special noise gate circuitry for Ultra & Crunch) Equalization: (Clean channel only) Custom Low, Mid, and High passive type EQ Voicing: (Ultra and Crunch channels only) Active Bottom, Body, and Hair (Edge) EQ Boost/Cut ±12 dB Dimensions and Weight: 11. ±3 dB 50 Hz to 20 kHz @ 90 W RMS into 8 Ohms Hum and Noise: Greater than 76 dB below rated power Power Consumption: Domestic: 400 W, 50/60 Hz, 120 V AC Export: 400 W, 60 Hz, 220-230/240 V AC Tubes: Three 12AX7s The following specs are measured @ 1 kHz with the controls preset as follows: Low and High EQ @ 10, Mid EQ @ 0 Ultra and Crunch Posts @ 10 Bottom, Body, and Hair EQ @ 5 Effects Send @ 0 Effects Return @ 10 Master Level @ 5 Nominal Levels are with Pre Gain @ 5 Minimum Levels are with Pre Gain @ 10 Clean Channel: Nominal Input Level: -20 dBV, 100 mV RMS Minimum Input Level: -30 dBV, 30 mV RMS Maximum Input Level: 0 dBV, 1.
