[. . . ] 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 DDTTM speaker protection with defeat switch Preamp out/power amp in jacks 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. [. . . ] GROUND LIFT SWITCH Provided to lift the ground on the XLR jack when ground loops are encountered. EFFECTS LOOP REMOTE SWITCH JACK This jack accommodates the remote footswitch (optional part number 00051000 ON/OFF single button switch), which is used to remove the effects loop from the signal path. The remote footswitch essentially acts as a bypass to punch in or punch out from your external effects. DDTTM SPEAKER PROTECTION DEFEAT SWITCH DDTTM speaker protection is defeated when the push button is in the "in" position. We recommend that DDT be enabled at all times to protect the speakers. PREAMP OUT JACK This 1/4" jack is used to route the preamp signal to external inputs, such as the input of an additional power amp. Use of this jack does not defeat the signal to the NitroBass amp (some volume difference may be noticed due to the impedance change experienced when adding an external unit to the signal patch). POWER AMP IN JACK This 1/4" jack is used to input an external signal to the power amp section of the NitroBass. Using this jack along with the preamp out jack creates a possible second effects loop. POWER CORD RETAINERS Use the Power Cord Retainers to wrap and store your cable while storing or transporting your NitroBass. SPEAKER OUTPUT JACKS These two 1/4" jacks provide the powered signal from the amplifier. Use one of the jacks to connect your speaker cabinet and the other to add a second speaker cabinet in parallel. The minimum speaker load impedance is 2 ohms (or two 4-ohm speakers in parallel). Warning: To prevent the amplifier from overheating, the front fan and rear-located vents should always remain clear of obstructions. 450 Watts RMS with 2 Ohm load 300 Watts RMS with 4 Ohm load RD 170 Watts RMS with 8 Ohm load Set to appropriate level for instrument used NOTE: "DDT should be utilized for maximum speaker protection" Slap Setting In Set to appropriate level for instrument used Doesn't matter when Mid is set to 0 Set as necessary Set to appropriate level for instrument used Mains Fuse = 8 amps Mains Voltage = 120 VAC 60 Hz Power Consumption = 350 watts Hum and noise: Typically greater than -89 dB unweighted with controls set as follows.
