Features and Connectors

1.1 Selecting channels and effect parameters

Use buttons 1 to 4 to select the MATRIX™’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.

supply. The MATRIX™ 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™. 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.

MATRIX™100 Head Rear

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!

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™ 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

MATRIX™ 120 COMBO

EXTERNAL SPEAKER: Connect cabinets with 4 ohms minimum
impedance to this jack.

MATRIX™ 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™ speaker
output is deactivated when a plug is inserted into this jack.

MATRIX™ Manual

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" 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
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™’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.

2) MOD FX knob is in 9:00 - 12:00 range
switch 1: MOD, switch 2: DLY (reverb is not connected)

3) MOD FX knob is in 12:00 - 15:00 range
switch 1: MOD, switch 2: DLY + REV

4) MOD FX knob is in 15:00 - 18:00 range
switch 1: MOD+DLY+REV, switch 2 remains free (as “global bypass
when single footswitch is used”)

After switching-on, the MATRIX 100 confirms the selected
configuration by making all four channel selecting switches blink
on and off a corresponding number of times. For example, once for
combination 1, and twice for combination 2, etc.. As soon as the LEDs
are flashing, you can let go of CLEAN and LEAD.

ATTENTION: If CLEAN and WARP are kept pressed down at the same
time, the entire AMP (all sounds and the FX-ON/OFF configuration) is
reset to the factory presets.

The MATRIX™’s four Channels

2.1 CLEAN

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

1.9 FOOTSWITCH

Your MATRIX™ 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™’s front panel. When the footswitch is plugged into the amp,
buttons 1 to 4 serve display purposes only, and the footswitch switches
channels.

1.10 FX ON/OFF

Especially for live performances, the MATRIX™ 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 seperately.

1.11 MATRIX FX-ON/OFF Programming

The switching function of the stereo socket FX-ON/OFF on the back
of the MATRIX can be programmed by turning the MOD FX knob and
holding CLEAN and LEAD pressed down. The following configurations
show which effects blocks are assigned in this way to switch 1 and
switch 2 of the double foot switch:

1) MOD FX knob is in 6:00 - 9:00 range
switch 1: MOD+DLY, switch 2: REV (factory preset)

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 head-room 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 some-where 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.

MATRIX™ Manual

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™’s heart of darkness, this channel offers fierce
high-gain sounds of a flavor 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™’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.

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 infinitely 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 spring
reverb. It handles and responds just like the original: Simply twist the
REVERB knob to adjust the spring REVERB’s volume.

3

The MATRIX™’s Effects

The MATRIX™ 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™ 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
