CARVIN ENGINEERING DATA OPERATING MANUAL

Congratulations on your purchase of the MTS3200 all tube amplifier. Carvin has
been building tube guitar amplifiers since 1949. They have been used by top profes­sionals like; Frank Zappa, Steve Vai, Craig Chaquico, Allan Holdsworth, Larry Carlton,
Chet Atkins and other great musicians. You will discover that these amplifiers repre­sent a significant sound improvement over conventional tube amplifiers. Spend time
with your new MTS3200 head or your MTS3212 combo and get to know it’s many
sounds.

TECHNICAL DESIGN OF THE MTS3200

The MTS3200 design criteria was to build an all-tube guitar amp that sounded better
than anything else on the market. This meant that the MTS3200 was going to be total­ly new from the ground up and that it was going to be an all tube design with no IC’s
or transistors.

HIGH IMPEDANCE GUITAR INPUT

Carvin has long known about the effects of miss-loading a guitar pickup which can
cause high frequency loss. The MTS3200 guards against this loss with its ultra high
input impedance. Also, we considered the capacitance of the average shielded guitar
cable which can reduce the high frequency response of your guitar pickups. Unlike
other amplifiers, we purposely avoided adding capacitance anywhere in the preamp to
control high frequency oscillations. Instead, we controlled oscillations through careful
component layout and lead placement allowing its shimmering highs to be reproduced.

CLEAN AND OVERDRIVE CHANNELS

The equalization of the clean and overdrive channel is designed to offer clarity to
your instrument. Special mud-cutting circuits eliminate the unwanted sounds in the
500 to 700 Hz range which normally take away the tone definition of your instrument.
You will also take notice of the clean channels PRESENCE switch which adds
acoustic voicing to your instrument. This switch boosts only the guitars very high­est harmonics which are in the 10k Hz range instead of the normal 3K Hz of a bright
switch. The PRESENCE control on the lead channel is designed to adjust the “edge”
on your sound. It’s dynamic range allows for super-smooth sounds or an edge for

your lead channel to reach out.

DYNAMIC 5881 POWER TUBES

Your amp is equipped with 5881 power tubes because of their smooth distortion,
responsive sound and reliability. The compression characteristics of these “soft clip”
power tubes respond to the dynamic range of lead guitar playing. These tubes react
even to the most subtle touch—if you play soft, the tubes remain clean and if you
increase your attack they respond accordingly.

TONE CONTROLS

The T-Bridge passive BASS, MID and TREBLE tone controls offer a wide range of
tone settings. Take full advantage by setting them where they sound best. Your
sound may not be at center 5 on the dial. These controls will not affect or color your
sound when set at extreme settings, nor do they interact with each other. The greater
range of these controls comes from the high impedance 1 meg sealed pots (most
guitar amps use 250k pots). The frequency of the bass control is set at 80 Hz while
the mid control is set at 650 Hz. The treble control is set at a very high 11k Hz giv­ing the MTS3200 it’s dynamic highs.

REVERB

The FS22 footswith for the long tailed REVERB system in the MTS3200 switches only
the reverb “send” leaving the tail of the reverb to decay naturally, the way it’s done in the
studio. A special pre filter eliminates the spring “boing” normally heard in other systems
giving it a “lush” sound. The all tube reverb system offers vibrant clarity with full depth
reminiscent of the sixties tube amps. Guitar Player magazine rated this system as one
of the best they have heard.

GETTING STARTED QUICKLY

If you are like most players, you probably want to plug in your new amp and get start­ed playing it right away. You can read the rest of the manual later to learn the finer points
of operating your amp. In order to get started you will need your MTS3200 amp, a 120
or 230 AC grounded power outlet, your instrument and a standard guitar cord. With the
amp turned off, you may now plug it into the proper AC voltage.

Now turn all the volume and drive controls off and set tone controls at their mid center
position. If you have purchased the FS22 foot switch, plug it into the rear foot switch jack
for switching the channels and reverb. Note: The channel SELECT button must be in the
OUT position (CH 1) for the FS22 to function (a hum will be heard if it’s in the wrong posi­tion).

Now, turn the power switch and standby switch ON. Allow 60 seconds for the tubes to
warm up. Gradually raise the volume controls and re-adjust the tone controls and your
ready to go. The brass knobs can feel hot after the amp has been on awhile. This is nor­mal because brass conducts heat while plastic does not. This will not cause a problem
for the controls. Please call if you feel your amp is malfunctioning. Occasionally tubes
are damaged in shipping.

FRONT PANEL

1. GUITAR INPUT

A standard 1/4” input jack feeds both channels through using the SELECT switch. Use
a professional quality guitar cord no longer than 25 feet. Typical cable capacitance should
be under 50pf—the longer the cord, the greater the capacitance (you can measure this
with a capacitance meter). A long cable with high capacitance will reduce the overall tre­ble response from your pickups.

2. CHANNEL SELECT

Set the channel SELECT switch to the desired channel. The LED’s next to the volume
controls will let you see what channel is functioning. Use channel 2 for clean playing.
Use channel 1 for overdrive/sustain. For the FS22 foot switch to function, set the chan­nel SELECT to the “ OUT” channel 1 position.

LEAD CHANNEL 1

3. LEAD CHANNEL INDICATOR

The red LED will illuminate when the LEAD channel is selected.

4. LEAD VOLUME

The volume of the lead channel is to be used as a master level control. For partial clean
output, set the VOLUME control to 10 and turn the DRIVE nearly off—under 1. By reduc­ing the guitar volume, you can use this channel as an alternate clean channel.

5. LEAD DRIVE

For mild tube saturation, set the DRIVE control between 1 & 2. For some of the best
saturation, set the control between 4 & 6. For full blown overdrive, set the control
between 6 and 10 (your guitar volume should be turned all the way up). Because the
MTS3200 has been “Hot Rodded” with so much gain in the DRIVE control, you will have
an abundance of guitar feedback. However, if feedback is a problem, reduce the amount

of DRIVE or move the guitar to the side or away from the speaker(s).

6. LEAD—BASS, MID & TREBLE

To start off with, set the BASS, MID & TREBLE controls at their center (5) position.
These controls are to be set according to the type of pickups used (dual or single coil).
It’s normal to decrease the BASS at higher playing levels. Try the PRESENCE control also
when adjusting the treble.

7. LEAD PRESENCE

Channel 1 features it’s own LEAD PRESENCE control for added clarity. It’s frequency
range is set at the mid range of the tonal spectrum. Careful adjustment with the TREBLE
control will make this feature very useful.

CLEAN CHANNEL 2

8. CLEAN CHANNEL INDICATOR

The red LED will illuminate when the CLEAN channel is selected.

9. CLEAN VOLUME

Channel switching from the Lead channel into Channel 2 gives you crisp, clean playing.
Thanks to special mud-cutting circuits that work between the frequencies of 500 and 700 Hz,
your guitar tones will be full and vibrant.

10. CLEAN PRESENCE

For added clarity, the CH 2 PRESENCE switch increases only the highest guitar harmonics
in the 8-10k Hz range which is ideal for acoustic guitars. A normal bright switch works only
in the 3k Hz range leaving your sound somewhat flat.

Single or dual coil pickups will deter-

mine the need for this switch.

11. CLEAN—BASS, MID & TREBLE CONTROLS

You can start at 5 on the dial for each of the tone controls. However, these settings do
not represent a normalize (flat) sound. You need to set them where they sound best!
Most musicians like to reduce the MID’S between 1 and 4 for deeper bass and crisper
highs. If your sound is too bright with single coil pickups, you may want to keep the
PRESENCE switch off.

MASTER SECTION

12. MASTER REVERB

Set the REVERB control for the desired amount (this works in both channels).

13. STANDBY SWITCH

Use the STANDBY SWITCH If you are taking a break. This turns the high voltage off,
increasing the life of your power tubes while keeping the power and preamp tube fila­ments on for immediate use.

14. POWER SWITCH & INDICATOR

The power switch is to be utilized as the master ON/OFF switch. As the amp is turned
on, the RED portion of the power switch will illuminate as your ON indicator.

REAR PANEL

15. SPEAKER JACKS

Two 1/4” SPEAKER JACKS are featured to operate several speaker systems at the same
time. Calculate the total speaker impedance based on parallel wiring as both speaker
jacks are wired in parallel. Select the IMPEDANCE SWITCH for the correct impedance.

16. SPEAKER IMPEDANCE SWITCH

The IMPEDANCE SWITCH offers the selection of 4, 8 or 16 ohms to match your speak­er system. The correct setting for two 16Ω speakers or cabinets would be 8 ohms. Select
the proper impedance. The impedance of the MTS3212 combo amp is 8 ohms. In the
case of adding another 8 ohm extension cabinet, keep the switch at 4 ohms.

17. 4 TUBE 100 WATT OR 2 TUBE 50 WATT OPERATION

For maximum output power, be sure the power tube selector switch is selected for 4
TUBE operation. For lower overall levels and early power amp clipping, move this switch
to the 2 TUBE operation. The volume reduction will only be 3 dB.

18. POWER TUBE BIAS SWITCH

If you desire to change from 5881 (6L6GC) to EL34 power tubes, you may do so by
selecting the external BIAS switch to the EL34 position on the rear panel. Be sure that
this switch is selected to the proper position or excessive heat will damage your tubes.

The internal P11 bias trim control can be set by a qualified technician. To set the bias,
measure the current across the terminals of the STAND BY switch (set this switch to the
off position when the amp is on). Set the idle current to 100 mA for all tube types.

19. VOICED LINE OUT

The LINE OUT 1/4” jack is “CABINET VOICED” to prevent excessive bass or highs going
to your mixer. This greatly aids in sound quality because you do not have to move your
mixer EQ setting to the extreme. The 1.5 VAC output (reference to 100 watts output at 8
ohms) is more than adequate to drive any professional mixer or power amp.

20. FS22 FOOTSWITCH

Most foot pedals with 2 switches, a stereo cord and plug will work. However, Carvin’s
FS22 is recommended because of the correct identification label on the foot switch. First,
the channel SELECT switch on the front panel must be selected to the “OUT” channel 1
position before the footswitch will work. Now that you are connected correctly, the chan­nels and reverb can be switched remotely. If a hum is heard in the speakers, the select
switch is in the wrong position (this will not harm the amp).

21. EFFECTS LOOP

For the lowest possible noise from an effects processor, use the effects loop instead of plug­ging the guitar into the effects and then into the amp. To use the EFFECTS LOOP, plug the
INPUT of your effects into the SEND jack and the OUTPUT of your effects into the RETURN
jack. Use shielded cables, not speaker cables. It’s normal to have a slight gain reduction of
several dB with some effects units. However, the amp has plenty of gain to overcome any
loss.

22. AC POWER & FUSE

The detachable AC POWER CORD supplied is designed to operate with one type of volt­age (the European 230V export model uses a CEE-7 plug cord set). Check the rear power
cord label for the proper voltage and fuse value. Make sure the cord is securely inserted
into the back of the unit. Plug the cord into a grounded “3” prong” power source. No
attempt should ever be made to defeat or use the amp without the ground connected.

The FUSE (some models have circuit breakers) is located within the AC power cord
receptacle. To check or replace the fuse, remove the power cord, place a screwdriver
under the “FUSE” cap and pull the fuse holder out. The fuse type is a 250V Slow Blow
SB 5 x 20mm rated at 3A for 120V & 1.5A for 230V models. Do not use fast acting fuse,
only a SLOW BLOW (SB) type fuse will work.

HELP SECTION

a) FEEDBACK FROM THE LEAD CHANNEL

The MTS3200 will feedback when the LEAD volume, DRIVE, TREBLE and PRESENCE
are turned all the way up. Like other highly modified tube amps, this is normal. To help
reduce feedback and noise, keep the DRIVE control set around 5 to 7 on the dial. Some
of the best lead saturation will be at around 5—not 10. Sometimes replacing V1
(12AX7A) can help reduce feedback.

b) TUBE REPLACEMENT GUIDE

It is not uncommon for tubes to malfunction during shipping. If your amp is not work-

ing properly, please call or refer to the following replacement guide.

1) The 12AX7A preamp tubes are located in the following order on your chassis: V1, V2,

V3, V4, V5. To start with, V1 is located next to the outside of your chassis behind the
output transformer. It is recommended to turn your amp upside down to replace
tubes. Replacing V1 will help reduce feedback in channel 1. Replacing V2 and V3 can
also help but V1 is the main tube to replace. Replacing V4 will correct problems with
the reverb system unless there is a defective reverb tank or tank cables. If the power
amp is not functioning, check or replace the 5881 power tubes and check V5 by
inserting a signal into the Effects RETURN jack. All tubes are keyed in the same direc­tion.

2) The 5881 power tubes are located in the following order on your chassis: V6, V7, V8,

V9. Normally you’ll want to replace these tubes as a set. Please call for our latest
prices. Sometimes you can spot defective power tubes when they are glowing red­hot along with an audible hum in the speaker when the amp is idling. If this happens,
shut the amp down immediately. After they have cooled down, remove by pushing
the retainers on the base of the tubes down and rock the tubes in a circular motion
while pulling them out. It is recommended to turn your amp upside down to replace
tubes. All tubes are keyed in the same direction. Running defective power tubes
could damage the amp. It is recommended that you have a spare set of power tubes
along with several 12AX7A preamp tubes.

MTS3212 Combo Review—By Simon Bradley

“Actually, the MTS3212 is a more versatile beast than I at first assumed, because, in the process of
turning the drive control all the way up, there are some excellent crunch tones along the way.

Maybe it’s the British Series (BR12) speakers, or the simple fact that the amp bristles with glow­ing tubes of loveliness, but these mid-driven sounds are of that responsive type that you just
can’t beat. It’s warm, of course, but vibrant enough to cut through, and the tone’s dynamic qual­ities would seem to offer musical assistance to all but the most colourless of blues players.

However, I would argue that it’s at high gains that this Carvin comes into its own. In this situa­tion, it’s one of the most satisfying amps I have played in a long time. EVH was once quoted as
saying that you know when you have a good sound when the guitar seems to play itself, and if Sir
Edward of Van plugged into this combo, he would be more than happy with the brown-ness of the
tone.

High octane rock sounds? No problem. Is mid-scooped thrash of angst-core your bag? Just
step this way, Sir. The EQ is simple because it has no reason to be anything else, such is the
efficiency of both the amp section and speakers to kick out a tone full of ballsy clout and high
end shimmer. Putting it through a 2 x 12 extension cab merely enhances the tone further.

Just when you thought it was safe to think ‘so…it’s like a Peavey 5150’ (yes, the overdrives real­ly are that good), a flick to Clean 2 will see you reaching for a Strat and switching to position 4.
An amp’s clean sound is, if anything, a more subjective affair than its dirty compadre, but I would
say that the MTS3212 has the best clean sound I’ve ever heard from a 100w combo. Others
might prefer a black-faced Fender Twin or even a Roland JC120, but the bass end available here
is nothing short of incredible. It has the potential to turn the sound of a single coil solid into
something akin to that of a monstrous f-hole jazz beast (should you so desire). Those in-betwee­ny Strat tones are well served, as is the neck position of a Gibson ES335, and the fact that the
combo can handle such diverse sounds with equal aplomb is a major feat.

Conclusion

Whatever styles of music you play, I have a feeling that you may well be blown away by this
Carvin. The price tag represents excellent value, and it could give other amplifiers costing twice
as much a serious run for their money.”

HELP SECTION

1) AMP WILL NOT TURN ON

Check the power to the amp. Check for tripped circuit breakers, unplugged extension cords or
power-strip switches that may be turned off. Check the fuse. If a dark brownish color or no wire
can be seen within the glass tube, then replace. The amp may be perfectly fine but occasionally
a fuse may blow because of high AC voltage surges. After the fuse has been replaced with the
proper Slow Blow value and if the fuse fails again, the amp will require servicing.

2) NO OUTPUT with POWER LIGHT ON

Tubes damaged in shipping will be the primary reason for your amp to not function properly.
Please give us a call to help guide you through this simple repair.

3) KEEP YOUR AMP LOOKING NEW

Use a damp cloth to wipe the controls on the front & rear chassis panels. Wipe the black vinyl
covering with a damp cloth.
