FEATURES OF THE AMPLIFIER

Front Panel

Rear Panel

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.

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.

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.

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 ¼

ʺ 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.

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

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.

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.

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.

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.

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 hand-tuned, 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.

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. 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.

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.

Channel1

No reverb is heard

Reverb sound has too much “echo”

Action

• 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.

• Automatic thermal protection is activating. Reduce the volume at least 30% and keep the amplifier out of direct sunlight or tightly enclosed spaces.

• Ensure the guitar plug is inserted fully into the INST-

HI 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.

• Ensure that the XLR or ¼ ʺ 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.

• Lower the source level.

• Lower the VOL 1 control.

• 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.

• Adjust the DWELL control

A “warbling” or pulsing sound is heard

Background hum

Excessive noise

Amp sounds garbled at all volumes

Desire clean tone, getting too much overdrive

• You may be hearing the tremolo effect. Check that the TREM control is set to its minimum position if this sound is undesired.

• 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.

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

• Check your cables, guitar and other effects in the signal chain.

• Check speaker by temporarily trying an external speaker. Caution: reduce volume until sound level has been confirmed.

• Turn down the GAIN control and turn up VOL 2.

• Set the Boost Voice Select to OFF.

• Turn up LIM.

• Use the INST-LO input.

• Try using the VOL 1 (CLEAN) Mode
