Standard “on-off” footswitches to remotely switch the “Stack” and “Channel”įunctions. These outputs can be used for monitoringĮffects, remote patching applications, etc. Stereo outputs A & B (both line and instrument level) can then be routed to either a stereo power amp, or two separateĭR Y OUT JACKS - Both Line and Instrument level output jacks for dry (before and independent of effects section) signal. NOTE: True Stereo operation is obtained when using a stereo or “panning”Įffects device plugged into both A & B Effects Receive Jacks. Both receive level controls can be adjusted (Use both Aī input jacks for receiving true stereo or “panning” effects).ĮFFECT S RECEIVE JACK (Ch B) - Effects receive jack forī. The signal will automatically be fed into Channel B receive. LEVEL (Ch A) - Adjusts receive sensitivity for Channel A effects. This output should be used to connect the unit to the input of a regular combo or stage amplifier instrument input.ĮFFECT S SEND LEVEL - Adjusts level output for effects send. OUT JACK (Ch B) - Instrument (guitar) level output level jack. This level will drive basic power amps, and operate at nominal line levels (0 dBm). LIN E OUT JACK (Ch B) - Line level output jack. Regular combo or stage amplifier instrument input. This output should be used to connect the unit to the input of a OUT JACK (Ch A) - Instrument (guitar) level output level jack. Use Channel A for MONO operation, however an identical signal is available at Channel B line output in MONO operation. LIN E OUT JACK (Ch A) - Line level output jack. The current draw is negligible, a maximum of only 10 watts is consumed,īut the unit can be damaged if proper voltage ratings are not adhered to. LIN E CORD - Be sure to connect the unit to the proper voltage source. Either LED or both light (depending on mode selected) when power is "on." POWE R SWITCH - Supplies main AC power to the unit. Channel 1's EQ is between the tube output in Channel 1 and before the tube in Channel 2. This is the overall Master Volume control in the "Stack" mode. STAC K MASTER - This control is operational only in the "Stack'“ mode. As channel 2 is primarily a clean channel, there is no dedicated master volume control it is
This control functions only with the single Green LED lit. LO W CONTROL - Shelves off lower frequencies from 100 Hz down. In the "Stack” mode, this control becomes a “Drive” control for the second tube Channel as well. MASTE R CONTROL - Sets the over-all output level of Channel 1. It is usually advisable to use thinner (lower numerical settings) for playing chords in overdrive, while single string leads may sound better with higher settings. Moving the control toward “10” gives a fatter sound, while toward “0” will give a thinner, more biting tone. Some players prefer a fatter, “Boogie" or "Fender" texture to their overdrive, while others prefer the more high-ended “Marshall” type edge. This, as well as the next control listed will have a great affect on the quality of the actual overdrive texture obtained as BOTH "Drive” and “Contour” are PRE TUBE controls. Increasing the setting of this control results in Wide-range for both Active pickupsĭRIV E CONTROL - Sets the amount of signal gain at the first stage of the tube for Channelġ. When a footswitch line is connected to the “Stack” jack on the rear panel. “Stack Master” is active only when the single Green LED is lit. With the stack mode selected, the “Channel” switch alternately selects Channel 2 (clean) The stack mode (Stack switch up) is when Channel 1ĭriven into Channel 2. STAC K SWITCH - Switches the unit in and out of the “Stack” mode.īOTH Green and Red LEDs light in this mode. Switch is overridden when a footswitch line is connected to the channel jack on the rear panel. This preamp with our MosValve power amplifier, as this combination will insure optimumĬHANNE L SWITCH - Switches between channel 1 and 2. Used with either basic power amplifiers or combo (Instrument level) amplifiers. Proper signal level and signal to noise ratio regardless Loop and adjust- able send and receive levels aid greatly in achieving WORKS PERFECT - VERY GOOD COSMETIC CONDITION!!Ģ allows it to remain clean even with high transient BK Butler REAL TUBE II RT922 Guitar Preamp
