We recommend that DDT be enabled at all times to protect the speakers. 25. 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. The signal is post volume control. 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). 6 7 REAR PANEL FEATURES: 27. POWER CORD RETAINERS Use the Power Cord Retainers to wrap and store your cable while storing or transporting your NitroBass. It is best to disconnect the cord from the unit before wrapping. 28. SPEAKER OUTPUT JACKS These two 1/4" jacks provide the powered signal from the amplifier. Each connector is electrically the same (in parallel). 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. 26. 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 will disconnect any signal from the preamp section. Using this jack along with the preamp out jack creates a possible second effects loop. 27 28 27 NITROBASS ™ Block Diagram Shelving EQMidrange InputTuner SendInstrument LevelBuffer-10 db PadIn/Out-10 db Pad Gain Bright Contour InfrasonicFilter Low Shelf(Bass)+/- 15 dBHigh Shelf(Treble)+/- 15 dB Buffer EffectsSendEffects Loop-10 dB, 0,315 VRMSEffectsReturnEffects LoopFootswitchSwitch LogicBuffer Volume CW Buffer Line Level1 VRMS, 0dBLine Level1 VRMS, 0dBPreAmp OutFull RangePwr Amp InStatus LEDGreen = Pwr OnRed = DDT/ClipGNDDT DefeatBuffer/DDTPower AmpExternalSpeaker Jack RDPre EQPost EQPre/Post EQSelect BalancedLine OutGround Lift 1 3 2Minimum Load is2 Ohms:450 Watts RMSwith 2 Ohm load300 Watts RMSwith 4 Ohm load170 Watts RMSwith 8 Ohm load1 2 Pre-Gain MidrangeShift200HZ - 2KHZMidrangeCut/Boost+/- 15 dB +- CW Line LevelOut Line Drivers 8 9 Rock Setting Out Set to appropriate level for instrument used Set as necessary NOTE: “DDT should be utilized for maximum speaker protection” Slap Setting In Set to appropriate level for instrument used Set as necessary NOTE: “DDT should be utilized for maximum speaker protection” Blues/ Country Setting Out Set to appropriate level for instrument used Set as necessary NOTE: “DDT should be utilized for maximum speaker protection” Doesn't matter when Mid is set to 0 NITROBASS™ Recommend Settings NITROBASS™ SPECIFICATIONS SYSTEM SPECIFICATIONS: 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… Pad = Passive Bright = Normal Pre gain = 5 Contour = 0 Low = 0 Mid = 0 Mid Shift = 1kHz High = 0 Volume = 5 POWER AMPLIFIER SECTION: PROTECTION: Electronic current limit protection circuit.
