Importante:

Thank you for choosing a Hughes & Kettner® product. With the MATRIX™ 100, you now own a unique guitar-driven sound system that offers everything you need to have a blast at rehearsals and on stage. We factored the wishes and suggestions of many guitarists into the design of the MATRIX™ 100, aiming to turn up a modern guitar amp that would stand as a benchmark DFX amp. We accomplished what we set out to achieve. No comparable amp comes close to matching the MATRIX™'s sound quality, fl exibility, performance and handling convenience.

Your MATRIX™ 100's nerve center is the innovative Autostore FX MATRIX™. For the first time, an amp in this class is able to store individual effect settings separately for every channel. And it does this automatically, without requiring additional programming steps. Finally, an ingenious function has arrived that makes the DFX amp a true gigging rig!

The MATRIX™ 100 is equipped with a digital multi FX processor offering popular effects such as REVERB, DELAY, CHORUS, FLANGER and TREMOLO in remarkably high quality. Four channels, a Current Feedback power amp and 12° RockDriver Ultra speakers, developed in a joint effort with Celestion®, deliver the goods – soul-stirring tone. When you power up and plug in, you'll hear 20 years of Hughes & Kettner® amp engineering experience reflected in that tone.

Whether you opted for the combo or the head, rest assured that the MATRIX™ delivers the kind of inspiring response that is sure to supercharge your playing while practicing and performing on the big stage. You wanted it all – powerful and G-force sound pressure, crystal-clear clean sounds, creamy CRUNCH and lead tones, fi re-breathing WARP sounds, and authentic effects. Now you got it, in a great, easily handled gigging amp to boot.

Here's wishing you tons of fun with your new MATRIX™ 100!

1 Overview of Control Features and Connectors

1.1 Selecting channels and effect parameters

Use buttons 1 to 4 to select the MATRIX™ 100's four channels, CLEAN, CRUNCH, LEAD and WARP. These buttons correspond to the buttons on the included footswitch. When the footswitch is connected, buttons 1 to 4 serve display purposes only, and the footswitch switches channels.

Use knobs 5 to 8 to adjust the effect for the given channel. The FX MATRIX's Autostore function automatically saves the edited effect settings for every channel. You do not need to store settings separately. Even if the amp is suddenly switched off or power fails, the FX MATRIX™ will recall your settings.

1.2 Instrument inputs, channels and master volume Connect your guitar to input 9. Please use high-quality shielded cords only.

Use knobs 10 to 21 to shape the sound and determine the volume of individual channels. You'll find a detailed description of the channels in section 2. Knob 22 determines the amp's overall volume level. Always turn the MASTER knob all the way down – that is, counterclockwise as far as it will go - before powering your amp up.

Knobs 10 to 22 work in the same tried-and-true manner as the controls on a classic amp. These settings are not stored.

This means that the actual position of the knob determines the amp's sounds.

1.3 Mains switch and mains socket

Use switch 23 to turn the MATRIX™ 100 on and off. Make a habit of checking to make sure that the switch is set to the OFF position before you connect the power cable to a mains power supply. The MATRIX™ 100 ships with a separate power cord that connects to socket 24. Please ensure that the mains voltage matches the value indicated on the back panel of the MATRIX™ 100. Get in touch with your Hughes & Kettner® dealer immediately if this is not the case or the included mains cord's plug does not fit into the wall outlet.

1.4 Speaker out

Use jack or jack pair 25, EXTERNAL SPEAKER or SPEAKERS, to connect speakers. All speakers are connected in parallel for both the combo and the head.

MATRIX™ 100 COMBO

EXTERNAL SPEAKER: Connect cabinets with 8 ohms minimum impedance to this jack. The impedance of connected speakers must never be lower than 8 ohms!

MATRIX™ 100 HEAD

SPEAKERS: You can connect two cabinets to the head. The minimum impedance is 4 ohms; ensure your rig's impedance never drops below 4 ohms! If you plug cabs into both jacks, each cabinet's impedance must be 8 ohms or higher. If you

plug a cab into just one jack, its impedance must be 4 ohms or higher.

1.5 Headphones out

Connect standard stereo headphones to jack 26, HEADPHONES. Adjust the volume via the MASTER knob. Always plug in a stereo 1/4" jack when connecting headphones. The headphones output may be damaged if you insert a mono plug into the jack. The MATRIX™ 100 speaker output is deactivated when a plug is inserted into this jack.

1.6 LINE OUT

Use jack 27, LINE OUT, (mono 1/4" jack) to patch out the amp's signal, including all effects, to another power amp or a DI box (for example, the Hughes & Kettner® RED BOX).

1.7 CD/LINE INPUT

Use jack 28, CD/LINE INPUT, to patch in any type of line signal. For example, you could plug in a CD player to play along with a recorded track. Use a cord equipped with stereo 1/4^st jack plugs to do this. Adjust the level using knob 22, MASTER VOLUME.

1.8 FX SEND/RETURN

Connect an effect device's output to jack 29, FX RETURN; connect an effect device's input to jack 30, FX SEND. The effects loop is a serial circuit, so adjust the effect amount (or wet-to-dry balance) at the effect device. The entire preamp signal is routed through the inserted effector and processed there. Please note that your rig's sound quality depends to a considerable extent on the quality of the employed effect device. A poor-quality signal processor can have an adverse effect on the MATRIX™ 100's sound quality.

• Use high-quality patch cords only to prevent signal loss, background noise and drop-outs.
• Ensure that the effect device is not being overdriven. Be sure to keep an eye on whatever type of level meter, gain indicator or overload lamp the effects device is equipped with, and adjust its input and output controls accordingly.
• Fuzz boxes, overdrives and distortion units don't belong in an FX loop. Plug them into the amp's input.

1.9 FOOTSWITCH

Your MATRIX™ 100 comes with a four-way footswitch that plugs into jack 31. The buttons on the footswitch correspond to buttons 1 to 4 on the MATRIX™ 100's front panel. When the footswitch is plugged into the amp, buttons 1 to 4 serve display purposes only, and the footswitch switches channels.

1.9.1 FX ON/OFF

Especially for live performances, the Matrix™ 100 enables you to turn the internal effects on and off individually, in addition to the 4 switchable channels. To do this, you need to connect a footswitch to the stereo 32 FX ON/OFF jack. Using a simple footswitch (such as the Hughes & Kettner® FS-1) will enable you to switch the modulation effects and DELAY at the

same time, leaving REVERB unaffected. You can use a double footswitch (such as the Hughes & Kettner® FS-2) to switch the modulation effects and DELAY, and REVERB separately.

2 The MATRIX™ 100's four Channels

2.1 CLEAN

The Clean is channel is tweaked to sound sweet when driven by single-coil as well as humbucking pickups.

2.1.1 CLEAN VOL

Adjusts the CLEAN channel's volume level. Players who opt for this class of amp demand a clean channel with enough headroom to ensure it remains clean. This amp certainly does that. Depending on the pickups' output power, you may also be able to dial in a touch of grit. For single-coils, we recommend that you turn the knob well up. Do this, and the amp will reward you with tight & punchy midrange response that is both crisp and fat. If your axe sports humbuckers, set this knob somewhere around the 12 o'clock position for crystal-clear clean tone.

2.1.2 Clean Voicing Section: BASS, MID and TREBLE

knobs. MID and TREBLE controls influence each other, as is standard and desirable in the tube amps that this voicing section is patterned on. If you boost the high end, mids are cut and vice versa. This sound-shaping feature lets you to dial in a wide variety of subtle tonal variations. We recommend that you go easy on the bass for the CLEAN channel. Generally, the more mids you dial in, the more assertive your clean tone in the band's soundscape. Note that the TREBLE knob shapes your guitar signal's bell-like overtones.

2.2 CRUNCH

Overdriven sounds à la carte! This channel covers a diverse tonal spectrum ranging from squeaky clean to gritty overdrive. It responds to every nuance in your picking attack, granting you precise control over the amount of overdrive via your guitar's volume knob. Higher CRUNCH knob settings elicit warm sustain that is ideal for singing leads with breathy dynamics.

2.2.1 CRUNCH GAIN

Controls the CRUNCH channel's input sensitivity and thus the amount of saturation. You can dial in anything from tone that is just sweet enough to pass for clean to throaty tones that are distinctly rough around the edges. Again, crank the knob for single-coils; back it off a bit for humbuckers.

2.2.2 CRUNCH VOL

Controls the CRUNCH channel's level; use it to determine the balance between it and the other channels.

2.3 LEAD

Yields hard-hitting, snarling British rock tone.

2.3.1 LEAD/WARP GAIN

Controls the LEAD and WARP channel's input sensitivity and thus the amount of saturation, with distortion option ranges from creamy smooth to British grit and chunky NuMetal thunder.

2.3.2 LEAD Vol

Controls the LEAD channel's level; use it to determine the balance between it and the other channels.

2.4 WARP

Beware! The MATRIX™ 100's heart of darkness, this channel offers fi erce high-gain sounds of a fl avor favored by popular NuMetal bands. This brand of distortion is best described as an angry roar. Depending on this channel's settings, you can dial monster NuMetal tone, grinding post-grunge and alternative sounds, and thunderous death and Gothic metal noise.

2.4.1 WARP VOL

Controls the WARP channel's level; use it to determine the balance between it and the other channels.

2.5 CRUNCH, LEAD, WARP Voicing Section

For handling ease, the MATRIX™ 100's three overdrive channels share common voicing controls. However, behind these tone controls are three different EQ circuits that are automatically switched along with the channel. This is why an EQ setting that you have dialed in for the LEAD channel works so well with the CRUNCH and WARP channels.

The MATRIX™ 100's Effects

The MATRIX™ 100 features three independent effects - modulation, DELAY and REVERB. All three effect models may be used simultaneously and adjusted independently. The MATRIX™ FX automatically stores settings for each channel.

3.1 MOD FX

The MATRIX™ 100 puts at your disposal the three most sought-after modulation effects: A CHORUS, FLANGER and TREMOLO are all assigned to one knob. CHORUS is assigned to the first third of the knob's control range, FLANGER to the second, and TREMOLO to the final third. You can sweep the knob within each third to adjust the effect's characteristics. We staked out the parameters so that you can swiftly and easily dial in settings that elicit good-sounding, useful variations of the desired effect. To switch off modulation effects, simply twist the knob to the far left. Twisting the knob clockwise adjust the modulation effect's rate. Modulation depth is adjusted automatically according to the rate setting so that every knob position yields

a hip effect sound offering real-world utility.

3.1.1 CHORUS

Low CHORUS settings yield a slow throb for thick, underwater sounds that work great with ballads. Courtesy of automatic effect depth adjustment, higher CHORUS settings do not evoke that dreaded "seasick" tone.

3.1.2 FLANGER

Slow FLANGER settings yield a stately sweeping whoosh effect, while faster settings give you swirly effects often heard in contemporary rock and pop tunes.

3.1.3 TREMOLO

Though the classic TREMOLO effect is great for recreating the sounds of '60s, it also serves up some hip effects that work wonders for contemporary tunes.

3.2 DELAY

DELAY is controlled via two knobs: TIME is an infi nitely variable knob that sweeps smoothly to the next repetition from 80 ms to 1400 ms. Feedback is adjusted accordingly and automatically. Short DELAYs with minimal feedback conjure great slap-back rockabilly sounds, while medium-length DELAYs are perfect for U2-style jangle. Long DELAY times let you come up with cascading, Queen-style licks. The VOLUME knob determines the level of repetitions, with a control range sweeping from off to as loud as the original signal.

3.3 REVERB

The REVERB is an authentic-sounding emulation of a classic springreverb. It handles and responds just like the original: Simply twist the REVERB knob to adjust the spring REVERB's volume.
