23. CLEAN TREBLE, MID, BASS
You can start at 5 on the dial for each of the tone controls. However,
these settings do not represent a normalized (flat) sound. You need
to set them where they sound best! If your sound is too bright, you
may want to reduce the PRESENCE control.
24. CLEAN EQX SWITCH
Toggle between standard EQ and Expanded EQ. This switch opens
a wider frequency range for the TREBLE, MID and BASS. Provides
a second set of tones to work with.
25. CLEAN PRESENCE
For added clarity, the CH 3 PRESENCE controls only the highest guitar
harmonics in the 5-10k Hz range. Careful adjustment with the
TREBLE control makes this feature even more useful.
REAR PANEL
26. SPEAKER OUTPUT 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 the speaker jacks are wired in parallel. Select
the IMPEDANCE SWITCH for the correct impedance.
27. SPEAKER IMPEDANCE SWITCH
The IMPEDANCE SWITCH offers the selection of 4 ohm, 8 ohm or
16 ohm to match your speaker system. The correct setting for two
16 ohm speakers or cabinets would be 8 ohms. The correct setting
for two 8 ohm speakers or cabinets would be 4 ohms. Select the
proper impedance.
28. 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 early power amp clipping at
lower levels, move this switch to the 2 TUBE operation. The volume
reduction will only be 3 dB.
29. POWER TUBE BIAS SWITCH
If you desire to change from EL34 to 5881(6L6GC) power tubes,
you may do so by selecting the external BIAS switch to the 5881/6L6GC
position on the rear panel. Be sure that this switch is set to the proper
position or excessive heat will damage your tubes. The internal bias
trim control P27can 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.
30. LINE OUT / LEVEL / CABINET VOICING
The LINE OUT 1/4” jack is for connecting to power amps or mixers.
The LEVEL control adjusts the output to prevent overloading amp or
mixer inputs. The CABINET VOICING switch will simulate the fre-
quency response of a guitar cabinet, and prevent excessive bass or
treble going to your mixer. This greatly aids in sound quality because
you do not have to make extreme adjustments to your mixer EQ. The
output level is more than adequate to drive any professional mixer
or power amp.
31. EFFECTS LOOP 2 PARALLEL- SEND/RETURN/TAIL
Effects LOOP2 is configured in
parallel. This means that the origi-
nal signal is left alone and effects from your processor will be added
into it. This provides the lowest possible noise from an effects proces-
sor without degrading your tone. To use the EFFECTS LOOP2, 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. Set your processor so that no direct signal is heard at the output
(MIX=100%). Adjust the effect level from your processor. If the proces-
sor has no adjustment, or is noisy, adjust the effect level with the LOOP2
RETURN knob. If your processor has a “Direct signal ON/OFF” set-
ting, it is usually better to turn it OFF, so you can set the processor’s
mix or effect level internally by preset. The TAIL switch keeps the
RETURN active after the loop is turned off, allowing reverbs and delays
to decay naturally, instead of being abruptly cut off.
32. EFFECT LOOP1 SERIES - SEND/RETURN/TAIL
Effect Loop 1 is a
series loop. This means it sends all signals through
your processor. To use LOOP1, 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. Adjust the processor MIX
setting to your liking. You may need to re-adjust your processor levels
so that your volume will be the same if LOOP1 is ON or OFF. If your
processor has a “Direct signal ON/OFF” setting, it is usually better to
turn it ON for LOOP1. The TAIL switch keeps the RETURN active after
the loop is turned off, allowing reverbs and delays to decay naturally,
instead of being abruptly cut off.
33. MIDI IN / THRU
Connect any standard MIDI controller to the MIDI IN jack with a 5-
pin MIDI cable. Connect the THRU to other MIDI units if used. (See
“MIDI PROGRAMMING” at the end of this page)
34. FS44 FOOTSWITCH
Use only the Carvin FS44. Buttons labeled “1”, “2”,”3” will choose
your amp channel 1, 2, or 3. The FS44 button labeled “EFFECT” will
turn on/off the BOOST function. DO NOT use MIDI devices in this
jack. Other footswitches will not work.
35. FS22 FOOTSWITCH
The switches on the FS22 footswitch control the EFFECT
LOOPS remotely. They work the same as the SMART
LOOPS switches on the front panel of the V3. Most foot pedals
with 2 switches, a stereo cord and plug will work. However,
Carvin’s FS22 is recommended because no rewiring will be
necessary.
36. AC POWER & CIRCUIT BREAKER
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. 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 circuit breaker is located above the AC power cord recep-
tacle. If the breaker activates, unplug the amp and check
the AC power connection, your speaker connection and all
tubes. If no problem is found and the breaker still activates,
your amp may need service.
MIDI
MIDI PROGRAMMING FEATURES:
The V3 will save the following settings in a MIDI program
patch (1 thru 100):
a.)The channel selection 1, 2, or 3.
b.)The LOOP1 and LOOP2 on/off settings.
c.)The BOOST on/off setting.
Volume, tone, and drive mode settings will not be saved.
TO ENTER MIDI / PROGRAM MODE:
1.) Hold down the channel SELECT switch for the channel
setting you wish to save (1,2,or 3).
2.) While holding down the first switch in step 1, press the
other two SELECT switches, and release
all three at the same time.
The LOOP1 LED will be flashing.
3.) From your MIDI controller, select (send) the MIDI patch number
you wish to save. The LOOP2 LED will flash once to confirm. Normal
operation is resumed.
To turn the
BOOST
on before saving the patch, (perform steps 1 and
2 above) then press and release the LOOP 1 switch. The green BOOST
LED will come on. Then perform steps 1-3 to save patch.
TO CHANGE THE MIDI RECEIVE CHANNEL:
1.) Press and release all 3 channel SELECT switches on the front
panel. The LOOP1 LED will be flashing.
2.) Choose MIDI channel 1, 2, or 3 by pressing the SELECT
switch 1, 2, or 3. The LOOP2 LED will flash once to confirm.
Normal operation is resumed.
HELP SECTION
A) FEEDBACK FROM THE LEAD CHANNEL
The V3 may feedback when the VOLUME, DRIVE, TREBLE and PRES-
ENCE are turned all the way up. Like other high-gain tube amps, this
is normal. To help control feedback and noise, reduce the DRIVE con-
trol, or move the guitar to the side or away from the speakers.
Sometimes replacing V1 or V2 (12AX7A) can help reduce feedback.
B) TUBE REPLACEMENT GUIDE
It is not uncommon for tubes to malfunction during shipping. If
your amp is not working properly, please call or refer to the follow-
ing replacement guide.
1) The 12AX7A preamp tubes are the smaller of the two kinds of
tubes, and are located in the following order on your chassis:V1,
V2, V3, V4, V5. To start with, V1 is located by the output trans-
former, which is behind the guitar input. Replace the tubes if your
amp does not work or sounds muddy or dull. V1 is the input
tube and affects all channels. V2 is the main drive tube for chan-
nels 1&2. Replacing V3 will correct problems with channel 3 and
the effect sends. Replace V4 or V5 if no output is heard when
putting a signal through (activated) effect returns.
2) If there is no output after replacing the preamp tubes, or if the
circuit breaker activates, try replacing the EL34 output tubes. The
amp should be rebaised after replacing the output tubes.
3) If the AC breaker should trip and turn the amp off, replace the
power tubes. Most likely one of these tubes might have a short.
