The new
UltraTM
Plus all-tube, 120 watt guitar amp head is designed for maximum tonal flexibility and power. This
three channel amp has features and tone rivaling amps 2 or 3 times its price.
Dial in any degree of Clean, Crunch, or Dirty with the amp’s three channels and switch among them from the front panel
or the footswitch. Peavey’s patented, three-way Resonance switch custom-tailors bottom end to your speaker cabinet
and room environment. A half-power switch provides low-volume output tube saturation and ideal power for practice or
small halls.
Determining which channel you are in is made easy by the large illuminated logo that changes color with channel
selection-Green for Clean, Yellow for Crunch, and Red for Overdrive. Gain boost and Bright push switches add extra
control over tone shaping.
Front Panel:
FRONT PANEL FEATURES
POWER SWITCH (1)
Switch to “on” position to turn on. The red LED will illuminate indicating power is being supplied to the unit.
STANDBY SWITCH (2)
Allows amp to be placed in Standby or Active mode. In Standby mode the tubes remain hot but the amplifier is not
operational.
3
RESONANCE SWITCH (3)
Used to fine tune the low frequency range of the speaker enclosure by varying the damping factor of the amplifier
between three presets.
OUTPUT SWITCH (4)
Allows selection of power amp output to be selected from full power (120 watts) to half power (60 watts output).
POWER LED (5)
Illuminates when AC power is being supplied to the amp.
STATUS LED (6)
Illuminates when amp is switched to “Standby” indicating amplifier is not operational.
MASTER VOLUME (7)
Controls the overall volume level of the system. Once a desired balance of the Clean, Crunch, and Ultra channels is
achieved, the entire system level may be increased or decreased with the Master Volume level control.
REVERB LEVEL (8)
Reverberation is an echo effect. Rotate clockwise to increase the effect. Remote footswitch can control On/Off.
EDGE (9)
An active tone control (Shelving type,
+I5 dB)
that varies the high frequency boost or cut.
Note: This control is not functional on the Clean channel.
BODY (10)
An active tone control (Peak/notch,
+I5 dB)
that varies the mid frequency boost or cut.
Note: This control is not functional on the Clean channel.
BOTTOM (11)
An active tone control (Shelving type,
*I5 dB)
that varies the low frequency boost or cut.
Note: This control is not functional on the Clean channel.
ULTRA VOLUME (12)
Controls the overall volume level of the channel. The final level adjustment should be made after the desired sound has
been achieved.
ULTRA GAIN CONTROL (13)
Controls the input volume level of the channel.
ULTRA GAIN SWITCH (14)
Boosts the overall system gain of the Ultra channel. Depress to the “in” position to activate.
CRUNCH GAIN SWITCH (15)
Boosts the overall system gain of the Crunch channel. Depress to the “in” position to activate.
CRUNCH VOLUME (16)
Controls the overall volume level of the channel. The final level adjustment should be made after the desired sound has
been achieved.
CRUNCH GAIN CONTROL (17)
Controls the input volume level of the channel.
HIGH, MID, & LOW EQ (18)
Passive tone controls that regulate the high, mid, and low frequencies.
BRIGHT SWITCH (19)
Provides a preset boost to treble frequencies. To activate, depress the switch to its “in” position. The bright function
affects only the Clean channel.
CHANNEL SELECT SWITCH (20)
Allows selection of the Ultra or Clean channel. The “out” position selects the Clean channel.
Note: Channel selection may also be accomplished by the remote footswitch. If remote selection is desired, the
Channel switch must be in the “in” (Ultra) position.
4
VOLUME (21)
Controls the overall volume level of the Clean channel.
LOW GAIN INPUT (22)
Provided for instruments that have extremely high outputs, which can result in overdriving (distorting) the High Gain
input. If both inputs are used simultaneously, the output levels are the same (both are low gain).
HIGH GAIN INPUT (23)
Used for most electric guitars. It is 6 dB louder than the Low Gain input.
Back Panel:
BACK PANEL FEATURES
IMPEDANCE SELECTOR SWITCH (24)
Used to select the appropriate impedance of the speaker enclosure(s). If two enclosures of equal impedance are used,
the switch should be set at one half of that value (e.g. for two 16 ohm enclosures, set switch to 8 ohms; for two 8 ohms
enclosures, set switch to 4 ohms).
SPEAKER OUTPUTS (25)
A
Paralleled
l/4”
output jacks for connecting speaker enclosure(s) to the amplifier (minimum is 4 ohms).
When using more than one enclosure, be sure to calculate the total impedance and set the Impedance
switch (24) accordingly. (See above section on Impedance Selector Switch).
Important: Use only high-quality, unshielded cable for speaker connections.
REMOTE FOOTSWITCH JACK (26)
Provided for the connection of the supplied remote footswitch. Footswitch is used to select the Ultra Gain, Crunch Gain,
or Clean channel and defeat Reverb.
PREAMP OUT (27)
The Preamp Out can be used to route the amplified signal to a mixing console, tape recorder, etc. Connect the Preamp
output using a shielded cable to an input of the tape recorder, mixer, etc. This patch does not affect the operation of the
amplifier.
EFFECTS RETURN (28)
Input for returning signals from external low-level effects or signal processing equipment.
EFFECTS SEND (29)
Output for supplying signals from external effects or signal processing equipment.
GROUND SWITCH (30)
A
Three-position, rocker-type switch which, in most applications, should be operated in its center (zero)
position. There may be some situations when audible hum and/or noise will come from the loudspeaker.
If this occurs, position the Ground Switch to either positive or negative (+ or - ), or until the noise is
minimized.
Note: Should the noise problem continue, consult your Authorized Peavey dealer, the Peavey factory, or a qualified
service technician. The Ground Switch is not functional on 220/240 volt models.
LINE CORD-120 V products only (31)
A
For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is not
advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment
without proper grounding facilities, suitable grounding adaptors should be used. Less noise and greatly
reduced shock hazard exists when the unit is operated with properly grounded receptacles.
