After all …

LIFE IS TOO SHORT FOR BAD TONE!

The 6100-DFX series of guitar amplifiers with on-board Alesisä 24 bit digital effects was designed to fill the
needs of the serious musician. Based on many years of guitar amplifier design, this family of tube hybrid am­plifiers is great for both the performance stage and rehearsal studio.

INPUT – The amplifier is equipped with a standard ¼” input. The input impedance is approximately 500k
ohms, which provides the most musical response from most guitar pickups. This is the basis for the smooth­ness of the tonal response, consistency of sustain and an overall reduction of noise. Additionally, the preci­sion input scaling preamp contains a 40 Hz, 12 dB/octave high pass filter (more effective and less intrusive
than the more common 6 dB filters) and an “RFI” filter (radio frequency interference) to eliminate high fre­quency noise.

CLEAN CHANNEL – The 6100’s clean channel is constructed using a monolithic FET amplifier for a clean,
sweet non-distorted sound. The tone is natural and open, lending itself readily to any musical style. The
CLEAN GAIN control uses “loop feedback” style circuitry for wide dynamic range and an exceptionally low
noise floor. Whether playing soft or hard, the responsiveness of the clean preamp is punchy and articulate.
The bottom end is solid, not muddy or overpowering.

TUBE DRIVE CHANNEL – Using a real 12AX7 dual triode preamp tube in our classic TUBE-DRIVERä to-
pology, we make this tube’s 2 discrete gain stages do things previously considered impossible. The TUBE
GAIN control uses “loop feedback” to control the drive level to the tube over a very wide range. This allows
for settings that include clean, overdrive and over-the-top distortion that are responsive to your individual
playing style. Set for clean or over-the-top, this preamp is warm, rich and full of natural harmonics. The TUBE
VOLUME control sets the overall volume of this channel. The noise floor and microphonics of this tube circuit
is exceptionally low, even at super-high gain settings.

CHANNEL SWITCH – switches between the CLEAN and TUBE channels. This function uses noiseless dual
FET switches for studio quality operation. Pushing the switch “in” switches the preamp from the CLEAN
channel to the TUBE channel. This function is foot-switchable from the jack located on the back panel.

BOOST SWITCH – switches additional gain into the tube channel allowing a more saturated overdrive
sound. Pushing the switch “in” adds gain to the tube channel. This function is foot-switchable from the jack
located on the back panel.

ATTACK SWITCH AND CONTROL – switches the attack circuit into the signal path, providing additional
post-tube gain. The ATTACK CONTROL varies the amount of attack gain switched into the circuit. This func­tion is foot-switchable from the jack located on the back panel.

CHANNEL DRIVE and CHANNEL SWITCH FOOTSWITCH – This tip-ring-sleeve jack will accept any 2­button push-on, push-off style footswitch (footswitch not included) which duplicates the front panel “BOOST”
and “CHANNEL SWITCH” switching functions via a standard ¼” (tip-ring-sleeve) jack. Any switch providing a
sustained contact closure may be used. TIP=BOOST, RING=CHANNEL SWITCH.

EFFECTS CANCEL and ATTACK FOOTSWITCH – This tip-ring-sleeve jack will accept any 2-button push­on, push-off style footswitch (footswitch not included) which duplicates the front panel “EFFECTS CANCEL”
and “ATTACK” switching functions via a standard ¼” (tip-ring-sleeve) jack. Any switch providing a sustained
contact closure may be used. TIP=EFFECTS CANCEL, RING=ATTACK.

MASTER 3 BAND EQUALIZATION – The EQ section is a wide range 3-band active equalization network. A
“flat” setting is obtained with the controls at the 12 o’clock positions. Using classic Baxandall circuitry and an
amplifier gain stage, this equalization network yields much tighter control over tonal character.

ALESIS

ä 24 BIT DIGITAL EFFECTS – All 6100 series amplifiers are equipped with a genuine 24 bit Ale-

sisä 15 program digital effects processor. Unlike other manufacturer’s built-in digital effects units, we chose
to use an industry leader in processing with an undisputed reputation for realistic, high quality effects algo­rithms. Level differences are normal when switching between different effects, adjust the “effects master”
level accordingly. A ¼” effects cancel jack (see above) is provided on the back panel to mute internal effects
via footswitch. Signal is muted when the switch is closed. The effect program labeled “bypass” is reserved for
use on amplifier modes with programmable preset switching and stereo processing and does not produce an
effect on the 6150 and 6190 models in the 6100 series. Effects include: 3– Plate Reverbs, 3– Room Re­verbs, 2– Hall Reverbs, 1– Rotary Speaker, 1– Chorus/Room, 1– Chorus/Plate, 1– Chorus, 1– Flange, 2–
Delays and 1– Bypass.

MASTER VOLUME – Adjusts the post-effects overall volume of the amplifier before the power amp. It
functions pretty much as you would expect!

POWER SWITCH – Turns the AC mains power on and off, indicated by green LED above switch.

EFFECTS SEND/RECEIVE JACKS – The ¼” send jack provides a nominal –10dB output signal to drive

any common effects processor with “wet/dry mix control”. This jack is configured as an “insert” jack and
interrupts the signal between the preamp and the power amp. The send jack can also be used as an un­balanced line level output. The ¼” return jack is used to return the processed signal back into the ampli­fier. This jack contains a switch that automatically opens the return jack signal loop when processing is
used. The “mix” control on the effects device is now used to set the balance between the
“wet” (processed only) and the “dry” (unprocessed) signals.

HEADPHONE OUTPUT– Used to connect standard headphones (8 – 600 ohm). A speaker switch on the
back panel shuts off the speaker on all models, allowing private practice or studio work with a minimum of
fuss and bother, not to mention noise! This output is short circuit protected.

XLR BALANCED DIRECT OUTPUT– This frequency compensated output is used to connect the ampli­fier to any standard balanced PA system mixer input. The level is nominal –30dBv (hot mic level) for
maximum flexibility. The ground lift switch opens pin 1 to eliminate ground loops between the amplifier
and the PA system. Select the position with minimum hum. This output is protected against phantom
power present on the mic input from the mixer console.

POWER AMPLIFIER – The 6100 series uses an integrated power operational amplifier to drive the load.
This fully monolithic design features complete short circuit and thermal protection built right into the sili­con die for high reliability under adverse conditions.

SPEAKER AND CABINET – The 6100 family uses Celestionä speakers, perfectly matched to the
closed back style cabinets. A bottom mounted tilt-back handle is provided so the amp can point up to­wards the performer. Finished in a textured vinyl finish, the cabinet sports a clean, no nonsense look that
shows that it is a serious music-making machine.

POWER INLET – A removable IEC style power inlet cordset is used to connect the AC mains power to
the amplifier. Various voltages and cordsets are available, depending on the destination country. An inter­nal (non-user replaceable) protection fuse is provided on the main circuit board. The Mains (line) voltage
is nominal 115 volts or 230 volts AC (depending on destination country), +/- 10%. The amplifier will oper­ate on either 50 or 60 Hz.
