GETTING STARTED

The first time you use your amplifier, we recommend that you set up the
front panel controls as shown in the illustration below:

Initial Settings:

• Set VOL 1 to its minimum position (we’ll use CH 1 later).

• Set GAIN, BASS, MID and TREB to their middle positions.

• Set LIM, TREM, and REV to their minimum position.

• Set PRES to its maximum position.

• Set VOL 2 to about ¼ level.

• Set the MODE switch to FULLQ.

Plug your guitar into the INST HI jack. As you play, use the GAIN and
VOL 2 controls to adjust the overdrive distortion and overall loudness of

the amplifier.

The tone controls (BASS, MID and TREB) are neutral in the middle
position. Turn them up and down to boost or cut their respective
frequencies.

The PRES control produces a crisp aggressive sound on full, and a more
mellow response when turned down.

4

For increased overdrive, move the BOOST selector to the LOUD position
and set the amount of additional gain with the BOOST level control. The
other boost settings change the voicing of the amplifier and are
described later in this manual.

Turning up the overdrive limiter (LIM) progressively reduces overdrive
distortion while maintaining lower-level sustain.

To add reverb, turn up the REV control. The DWELL control sets the
decay time of the reverb tail. Use the PATH switch to select which
channel or mix gets reverb. Use the MIX, PRE or POST settings when
playing Channel 2.

The next section of the manual will describe in more detail each control
and feature of the amplifier.

5

SWITCHABLE 2 CHANNEL OPERATION

The MicroPro 200 features two independent amplifier channels,
combined into a single speaker, which can be used separately or
simultaneously. Each channel has a maximum RMS output of 100 watts.
CH 1, the MIC/LINE channel, may also be used as a “clean” channel, with
access to minimal effects. CH 2, the Instrument channel, is typically used
as the “overdrive” channel and which can use all the amp’s effects.

In normal 2-channel mode, VOL 1 controls the loudness of the MIC/LINE
input and VOL 2 controls the loudness of the INSTR inputs.

“Clean–Dirty” Preset

To use VOL 1 as a clean-channel preset, set the
MODE switch to VOL 1 (CLEAN). The INSTR
input is now routed through Channel 1 and is
controlled by its master volume (VOL 1).

By adjusting the VOL 1 and VOL 2 controls, you
can achieve a balanced loudness level between
the two channels.

(There is no special overdrive circuitry on Channel 1, but you may still
hear some distortion if exceeding the 100 watt limit.)

When switched to Channel 1, the MODE backlight color changes from
Blue (FULLQ) to Orange (VOL 1), to remind you to use the VOL 1 control.
Controls that are reserved for Channel 2 presets have their LEDs turned
off. BASS, MID, TREB are still effective; reverb can be used when the

PATH switch is set to the CH 1 or MIX positions.

Footswitch control:

In this mode, the footswitch can route your sound from the clean channel
to the overdrive channel by engaging the MODE switch.

Using the BOOST and LIM footswitches can give you even more
switchable tonal presets when using Channel 2.

6

FRONT PANEL CONTROLS AND FEATURES

Channel 1 (CH 1) Combination Input

A microphone input plugs into the XLR portion of the
MIC/LINE input jack. A mono, line-level input
connects using the ¼ʺ center portion of the jack.

This channel works well with dynamic microphones,
acoustic guitars with built-in preamps, keyboards and
playback of accompanying music.

Channel 1 is also a good choice if you use a preamp or modeling
processor before the amplifier. The rich, open sound of the amplifier
works as an ideal canvas for digital modeling and effects.

This channel is essentially free of distortion; however you may hear some
distortion when exceeding the 100 watt rating.

Channel 1 Volume

VOL 1 controls the loudness of the MIC/LINE input.

Except for certain reverb settings (see below), this is the
only control that affects the MIC/LINE inputs.

Channel 1 Reverb

To use reverb on Channel 1, set the PATH switch to CH 1 or MIX
positions.

Channel 1-2 Switching

When the MODE selector is in the VOL 1 (CLEAN) position, Channel 2’s
INSTR signal is routed through Channel 1 and responds to VOL 1, BASS,

MID, and TREB.

7

Channel 2 (CH 2) Inputs

Channel 2 is tailored for electric guitars. INST-HI

has a 2 meg input impedance that preserves the
delicate overtones of standard pickups. INST-LO
has a 100K impedance and 6 dB attenuation
which may work well with active guitar pickups.
Use the input that sounds best to you.

If two guitars are plugged in at once, they are blended together but each
one reduces the output of the other somewhat.

Channel 2 has 14 highly active controls which are explained in
detail below.

Channel 2 Preamp Gain (Overdrive Channel)

The threshold of overdrive depends on playing style and
type of guitar pickups. With no added Boost (see below),
the sound should be clean below GAIN settings of “3” (as
shown in the illustration to the left). Somewhere between
“3” and “6”, the amp should begin to overdrive on loud
notes. Overdrive should increase greatly as GAIN is
increased to “10”.

Channel 2 BOOST Section

The BOOST control (on the left) sets the amount of additional boost from
3dB to 15dB. The BOOST VOICE selector (on the right) can be OFF, or set

8

to one of four boost voices, SCOOP, BRIGHT, LOUD and HOT, each of
which provides a different kind of boost with its own musical value.

BOOST Voice Settings:

OFF – No additional gain is applied
SCOOP – This voice boosts gain with a slight midrange scoop, adding

relatively clean volume with more bass and treble ”chime.”
BRIGHT – This voice boosts upper midrange and treble for more
penetration and “clang.”

LOUD – This voice boosts all frequencies equally for more overdrive.
HOT – This voice produces an aggressive type of overdrive, at a level

similar to the maximum clean volume, as one type of “lead preset.”

• Note: the PRES control can be used to help tame the high end if

the distortion sounds too bright and “fizzy.”

Footswitch control:
The footswitch bypasses BOOST when the LED is off, and activates the
selected BOOST when the LED is on. When the boost voice selector is in
the OFF position, the boost footswitch has no effect even if the LED is on.

Active Tone Controls

The BASS, MID and TREB controls adjust equalization or tone for the
INSTR inputs, whether routed to CH 1 or CH 2. The controls are active
boost/cut controls with a neutral response on their middle detent (“5”).
Up to 12dB of boost or cut is available depending on frequency. The
frequencies and control curves have been carefully designed to enhance
the sound of the electric guitar.

9

Unlike the traditional “tone stack”, the MicroPro controls are totally
neutral at their center position. This allows you to hear the natural
sound of your guitar before you start making adjustments. Only slight
adjustments may be needed depending on the type of guitar you
are using.

Overdrive Limiter

Intentional use of overdrive greatly expands the range of
the electric guitar, adding sustain and exciting overtones
to the basic plucked sound. The internal overdrive limiter
adds more versatility by preserving overdrive sustain
while controlling the amount of distortion.

Zero LIM permits full overdrive. Setting LIM at “2” or “3” keeps overdrive
down to a “rolling boil.” Higher settings continue to replace overdrive
distortion with a clean, singing sustain. In effect, LIM replaces overdrive’s
“hard ceiling” with a softer cushioned ceiling that can be adjusted to
taste. The trade-off is that the “feel” of limiting is more elastic or rubbery
than normal overdrive.

Footswitch control:
When the footswitch is engaged (LED on), LIM is active and overdrive will
be reduced in accordance with the control setting. When the footswitch
is off, the limiter is bypassed. Enabling and bypassing the limiter offers
yet another preset to transition from clean to overdrive.

Tremolo

Tremolo was one of the first effects offered on vintage
amplifiers. To avoid panel clutter, the MicroPro 200 uses a
single TREM knob, with a fixed depth and unusually wide
frequency range, adjustable from a very slow breathing to
a fast staccato. To support exact matching of the pulse
rate, this knob has smooth, non-detented operation, and
of course, a footswitch bypass.

10

Reverb Section

The MicroPro 200 uses a premium
digital reverb chip with a smoother
decay and a lower noise floor than a
classic spring tank. The reverb is
voiced to “float” nicely in the mix.

The REV control sets the amount of
reverb added to the signal.

The DWELL control adjusts the
decay time from a short “klonk” to a
lush “heavenly choir.”

The PATH switch controls whether reverb is applied to CH 1, CH 2 or
both, as well as offering some additional variations on the reverb sound
and how it interacts with Tremolo.

• CH 1 – Applies reverb only to CH 1(MIC/LINE).

• MIX – Applies reverb to CH 1 and CH 2 after the overdrive stage. This

produces cleaner overdrive, with reverb applied afterwards, as in a
studio or recording session.

• PRE (CH 2 only) – Reverb is applied before the gain, tremolo and

clipping stages. The tremolo applies to the reverb as well as the
direct signal, and the reverb will get very “large” at high gains.

• POST (CH 2 only) – Reverb is applied after the gain and tremolo

stages but before clipping. The reverb is post-tremolo, which
reduces tremolo depth somewhat, and produces more controlled
reverb levels at high gains.

Footswitch control:
The footswitch LED is on when reverb is active, and off when bypassed.
The footswitch controls the signal at the input of the reverb stage. When
turned off, the remaining reverb tail decays naturally. This means you
can “deposit” a burst of music and let it taper off while you continue to
play dry.

11

Presence

The PRES control adjusts the overall sound of Channel 2,
including any overdrive, from a mellow “singing” quality
to a crisp full-range attack, to suit the style of music.

Maximum Presence delivers the amplifier’s full frequency

range for a crisp, aggressive sound. Turning down the
control produces a mellower, singing quality that may enhance a blues or
jazz style, and tames a harsh or overly bright tone.

Channel 2 Master Volume

VOL 2 is the master volume control for Channel 2. It

regulates the overall loudness of the channel without

altering the amplifier's tone or overdrive. Lower settings

are suitable for practice or quiet venues. High settings

enable the amp to compete on stage with drums or much

larger amplifiers.

TIP: For a loud, clean tone, set VOL 2 full up, and adjust the GAIN control
to the desired volume. LIM can also be increased to prevent unexpected
overdrive.

Mode Selector

MINI, TWEED and CLASSIC are analog

emulations that capture the tone and dynamics
of several classic amplifier types. FULLQ is the
natural, full-bodied sound of the MicroPro, and
the default position that the MODE footswitch
returns to.

VOL 1 (CLEAN) shifts the signal to CH 1,
allowing for a clean preset.

12

MINI MODE
Represents a small battery-powered or practice amp with rather abrupt
overdrive and very limited bass response. Often useful as a “novelty” or
“toy” alternative to the normal FullQ sound of the amplifier.

TWEED MODE
Represents a 1950’s era amplifier, with a mellow tone, chesty open-back
bass response, and rich, chewy overdrive similar to “cathode-bias”
circuits.

CLASSIC MODE
Similar to larger ‘60s era amplifiers, with fairly full-range bass, a slight mid
scoop, and crisper “fixed-bias” overdrive. The result is slightly glassier
sounding compared to FullQ.

FULLQ MODE
This sound represents the full development of the Quilter tone. It
combines the open airy quality and fast attack of modern direct-coupled
circuitry with the rich chewy overdrive normally found only in hand­tuned, open-loop amplifiers. Each of the vintage sounds has its charms,
but FullQ represents “high definition” guitar amplification at its finest.

VOL 1 (CLEAN) MODE
This is a special mode designed to allow two-channel switching. When in
this mode, the VOL 1 control sets the clean gain. Certain CH 2 controls,
GAIN, LIM, PRES, BOOST and VOL 2 are reserved as presets for the FullQ
mode. Note that the LEDs above these controls go out in VOL 1 mode.

Footswitch control:
When the footswitch is engaged (LED on), the FULLQ mode is active, as
indicated by a blue color. When the footswitch is off, the mode selected
with the knob becomes active, as indicated by orange and amber colors.
When set to VOL 1 (clean), the MODE switch allows you to go from clean
to an overdrive tone.

13

Back–lit Control Panel

The glowing blue Quilter logo lets you know the power is on while the
control legends make the front panel of the amp easily readable in a
dark room.

Footswitch control:
When the footswitch is used to bypass various controls, their panel LEDs
are turned off, helping you see which features are bypassed.

Rear Mounted AC Power Switch

Simply reach over the right side of the amp to flip the power
switch on and off.

International Power Supply

The MicroPro 200 can be used on all known domestic AC voltages
(100-250V) which allows you to play just about anywhere on the planet.

Locking IEC Power Cord

The power cord that comes with your amplifier
is designed to lock into the AC inlet to reduce
the chance it will come unplugged during use.

Press the yellow button on the cord to release
it. Any normal 3-prong IEC cord can still be used with the amplifier as
well. Always ensure that the ground contact is intact on both the cord
and receptacle.

Speaker Outputs

The MicroPro combo amplifier models (MP200-8, MP200-10 and MP200-

12) come with the internal speaker plugged into the INT SPEAKER
output. An external 8 ohm speaker may be used in place of the internal
speaker by unplugging this cable and connecting the external speaker.

14

An external 4 ohm speaker cabinet should be connected to the EXT

SPEAKER output.

To use two speaker cabinets simultaneously, connect a 4-8 ohm
extension speaker with a minimum of 200 watts continuous power
handling to the EXT SPEAKER output and an 8 ohm cabinet (or the
internal speaker) to the INT SPEAKER output. Circuitry adjusts the output
impedance to split the power between the two outputs.

MicroPro 200 Head: Connect a single 4 ohm speaker
cabinet, to the 4 OHM SPKR output or an 8 ohm
cabinet to the 8 OHM SPKR output. When using two
cabinets, a 4-8 ohm cabinet can be used in the 4 OHM
SPKR output and only an 8 ohm cabinet should be

connected to the 8 OHM SPKR output.

CAUTION: the amplifier can deliver up to 300 watts peak, well beyond the
capacity of most single speakers. We recommend Quilter extension
cabinets with power tested speakers. Quilter Labs will not be liable for
damage to other speakers.

Effects Loop

The SEND jack combines both channels at -10dB
which matches consumer and pro effects. The
RETURN jack interrupts the internal signal, and
returns the effects output directly to the power
amplifier.

Impedance is low which preserves tone, and the SEND jack remains
active which keeps effects synchronized. Effects are therefore applied to
the overall sound of both channels with outstanding headroom and
clarity.

Footswitch control:
Without the footswitch attached, the effects loop is activated when using
the RETURN jack. The effects loop is enabled when the footswitch LED is
on, and bypassed when the LED is off.

15

Footswitch Jack.

The foot controller connects with the supplied cable.
Both jacks on the foot controller are wired identically, so
you can plug into either one. A standard network cable
with RJ-45 connectors may be used as an emergency
replacement or if you need a longer cable.

Direct Output

The isolated direct output allows you to route the output
sound of the amp to a mixing board or external powered
loudspeakers without using a microphone. The signal level
is compatible with mic inputs, and is padded down from
the actual signal across the speaker, to preserve as much of
the tone quality as possible.

A high frequency rolloff is included to prevent high frequency system
instability, and produces the same tone quality through full-range
speakers as the internal single-cone driver.

Caring For Your Amplifier

Clean the outer surfaces with a clean, damp cloth or vacuum with a soft
brush. Never use any abrasives, harsh cleaners or solvents.

The MicroPro 200 amplifier is manufactured with high quality
components using modern industrial processes that greatly reduce
production defects. Each amplifier goes through an intensive testing
process before it leaves the factory ensuring that your amplifiers will give
you years of flawless service. There are no user-serviceable parts inside
the amplifier. Any repairs should be performed by a trained service
professional.

Always use the amplifier in a well-ventilated environment and protect
from external heat sources such as furnaces or direct sunlight.

Prolonged high-volume playing causes heat buildup in the speaker
which reduces its working lifetime. If you find it necessary to consistently
use the amp at full volume, we recommend using an extension speaker
to prolong speaker life and improve sound coverage.

Troubleshooting

Symptom

Action

No power, no lights

• Ensure that the AC cord is fully seated and connected

to a live source.

• Check the AC source by trying another device such as

a lamp.

Amp turns off then after a

short time, turns back on

• Automatic thermal protection is activating. Reduce

the volume at least 30% and keep the amplifier out of

direct sunlight or tightly enclosed spaces.

No audio (using a guitar)

•

Ensure the guitar plug is inserted fully into the INST­HI or INST-LO inputs.

• Try using a different guitar cable.

• Check that the pickup selector switch and volume on

the guitar are set correctly.

• Remove any cables from the RETURN jack of the

Effects Loop. If this corrects the problem, ensure that
the signal from the SEND jack passes through all
effects in the chain.

• Ensure that the rear panel speaker plug is fully

inserted into the INT SPEAKER jack.

If the MODE switch is set to VOL 1:

• Check that the VOL 1 control is not on its minimum

setting.

If the MODE switch is NOT set to VOL 1:

• Check that the GAIN control is not on its minimum

setting.

• Check that the VOL 2 control is not on its minimum

setting.

No audio (using the

MIC/LINE input)

• Ensure that the XLR or ¼ʺ plug is fully inserted.

• Try using a different cable.

• Check that the VOL 1 control is not on its minimum

setting.

• Ensure that the rear panel speaker plug is fully

inserted into the INT SPEAKER jack.

• Remove any cables from the RETURN jack of the

Effects Loop.

Distorted audio on

Channel1

•

Lower the source level.

•

Lower the VOL 1 control.

No reverb is heard

•

Check that the PATH switch is set to CH 1 or MIX
when using the MIC/LINE input or the VOL 1 mode.

• Check that the PATH switch is set to MIX, PRE or POST

when using the CH 2 inputs.

Reverb sound has too
much “echo”

• Adjust the DWELL control

18

A “warbling” or pulsing

sound is heard

• You may be hearing the tremolo effect. Check that

the TREM control is set to its minimum position if this

sound is undesired.

Background hum

• Ensure the guitar plug is fully inserted.

• Try using a different guitar cable.

• Any AC powered sources or effects should be

plugged into the same receptacle as the amplifier to
help avoid ground loops.

If the hum goes away when you turn down the guitar:

• Single coil pickups can be a source of hum, especially

if near RF sources like light dimmers or neon lights.
Some guitars have a mode where two pickups are in
reverse polarity to each other. This mode can often
reduce hum.

• Check that the guitar’s cavities are well shielded.

Excessive noise

• At high gain settings, some audible hiss or whoosh is

normal.

• Check your cables, guitar and other effects in the

signal chain.
