A.INPUTS—Plug into either (or both) of the input jacks using a shielded instrument cable. Press Input Select to choose either input 1 or 2 to be the active jack as indicated by the LEDs.

The rear panel In jack {LL} can be used instead of input 1 on the front panel; useful for connecting wireless receivers. NOTE: If both of these jacks are used at the same time, the front panel jack overrides the rear panel jack.

TIP:To overdrive the first tube stage of the preamp, connect an external preamp inline between your instrument and the input. For the best pure-tube overdrive sound, boost the out- put of your external preamp, then dial in a clean Gain setting using the PreAmp Clip LED {P}. (The Preamp Clip LED does not monitor the very first preamp tube stage to allow you to isolate it and overdrive it independent of the Gain controlled stage of the preamp.)

B.MUTE—Press in to disable all output from the unit, except Tuner Out {KK}; useful when switching or tuning instruments or during breaks.

C.p ad— Press in to reduce input sensitivity by –10dB; useful for cleaner response from high-output instruments.

D.BASS INTENSIFIER—Press in to engage the Bass Intensifier circuit as indicated by the LED. The Bass Intensifier boosts a chosen set of low frequencies combined with a smooth, fast-acting compressor, providing radical boosts without overdriving the amplifier; useful for heavier sections of a tune. Bass Intensifier can also be engaged from the footswitch.

E.LEVEL—Adjusts the strength of the Bass Intensifier effect.

F.CUTOFF—Limits the frequency range that the Bass Intensifier operates in from below 80Hz to below 200Hz.

G.COMPRESSION—Press in to engage the Compressor circuit as indicated by the LED. Compression moderates signal level as it peaks, according to the way you have controls {H, I, K and L} set.

H.t hreshold— Sets the signal level at which Compression engages. Turn fully counter-clockwise for maximum sensitivity. Note that Gain {Q} level and instrument output are what actu- ally trigger the Compressor.

I.RATIO—Adjusts how much compression is applied once it has been triggered. For example, at 1:1 there is no compres- sion. With a ratio of 2:1, an increase of 10 dB will be needed to increase the output signal level by 5 dB over the threshold. At 10:1, an increase of 10 dB will only increase the output signal level by 1 dB. (Many consider ratios of 10:1 and greater to be hard limiting.)

J.COMP POSITION—Press to alternate the position of the Compressor circuit in the signal path from before most of the tone shaping controls to after, as indicated by the LEDs. See Block Diagram on page 11.

K.ATTACK—Adjusts the rate that Compression engages once the the signal level rises above the threshold; useful for fine tuning the transparency of the Compressor effect.

L.r elease— Adjusts the rate that Compression disengages once the signal level drops below the threshold; useful for fine tuning the transparency of the Compressor effect.

M.METER—Four LEDs indicate the actual amount of gain reduc- tion in dB.
