Thank you for buying Peavey! Features: • Compact top box design • 450 watts into 2 ., 300 watts into 4 ., 170 watts into 8 . • Three-band active EQ with shiftable mid-range control • Contour control • -10 dB pad switch (active/passive pickup switch) • Buffered tuner send jack • Footswitchable post-EQ effects loop • Electronically balanced XLR jack • Pre-/Post-EQ send switch for XLR jack • Ground lift switch for XLR jack • DDT™ speaker protection with defeat switch • Preamp out/power amp in jacks 3 AC POWER FEATURES: 1. REMOVABLE AC POWER CORD This receptacle is for the IEC line cord (included), which provides AC power to the unit. Connect the line cord to this connector and to a properly grounded AC supply. Damage to the equipment may occur if an improper line voltage is used. (See voltage marking on unit.) Never remove or cut the ground pin of the line cord plug. This unit is supplied with a properly rated line cord. When lost or damaged, replace this cord with one of the proper ratings. NOTE: FOR UK ONLY As the colors of the wires in the mains lead of this apparatus may not correspond with the colored markings identifying the terminals in your plug, proceed as follows: (1) The wire which is colored green and yellow must be connected to the terminal which is marked by the letter E, or by the earth symbol, or colored green or green and yellow. (2) The wire which is colored blue must be connected to the terminal which is marked with the letter N, or the color black. (3) The wire which is colored brown must be connected to the terminal which is marked with the letter L or color red. 2. POWER SWITCH This switch is used to turn the NitroBass on or off. To turn the unit on, flip the switch to the “on” position. 3. GROUND POLARITY SWITCH Three-position, rocker-type switch, which for most applications should be operated in the center (zero) position. If hum or noise is present with the ground switch in the center position, place the ground polarity switch to positive or negative (+ or -) to minimize hum; should a problem continue, consult your authorized Peavey dealer, the Peavey factory, or a qualified service technician. Note: The ground switch is not available on 220/240 volt models. 4. FUSE The fuse is located within the fuse holder on the rear of the unit. If the fuse should fail, IT MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair. 4 REAR PANEL 4 2 1 3 NOTE: THE FUSE SHOULD ONLY BE REPLACED WHEN THE REMOVABLE POWER CORD HAS BEEN DISCONNECTED FROM ITS CHASSIS RECEPTACLE (1). 5. POWER/STATUS LED Located on front panel this LED illuminates green when the Power Switch is in the “ON” position and AC power is supplied. During normal operation the LED also acts as a DDT indicator. The LED illuminates red when the DDT speaker protection is active. When DDT is defeated, the LED will illuminate red when clipping occurs. FRONT PANEL FEATURES: 6. INPUT JACK This input will accept signals from all types of bass pickups. 7. INPUT PAD SWITCH Provided for instruments that have extremely high output, which can result in overdriving (distorting) the input stage. Pressing the switch to its “in” or “active” position reduces the level of the input signal by 10 dB. 8. BRIGHT SWITCH Provides a preset boost to treble frequencies when pressed. 9. TUNER SEND JACK A 1/4" jack is provided for connecting an instrument tuner. This jack is buffered off the input jack so it is just like plugging directly into the tuner. 10. PRE GAIN CONTROL Controls the input gain of the preamplifier. 11. CONTOUR CONTROL Provides a specially voiced EQ as the knob is rotated clockwise. When the knob is fully counterclockwise (set to 0), there is no voicing added. 12. LOW CONTROL An active tone control (shelving type, ±15 dB) that varies the low frequency boost or cut. 5 9 18 17 19 20 23 21 22 25 26 6 7 8 10 11 12 13 14 15 16 5 24 13. MID CONTROL An active tone control (peak/notch, ±15 dB) that varies the midrange boost or cut. 14. MID SHIFT CONTROL Selects the frequency band (200 — 2 kHz) that the mid control cuts or boosts. 15. HIGH CONTROL An active tone control (shelving type, ±15 dB) that varies the high frequency boost or cut. 16. VOLUME CONTROL Controls the overall volume level of the amplifier. The final level adjustment should be made after the desired sound has been achieved. 17. LINE OUT—XLR JACK Provides low impedance, electronically balanced signal for patching into a sound reinforcement or recording console. 18. LINE OUT LEVEL CONTROL Controls the output level of the balanced line out. 19. PRE-/POST-EQ SELECT SWITCH Allows selection between a Pre-EQ (switch set to the “out” position) or a Post-EQ (switch set to the “in” position) send to the XLR line out jack. 20. GROUND LIFT SWITCH Provided to lift the ground on the XLR jack when ground loops are encountered. 21. EFFECTS SEND...
