GLHDE
Congratulations on your purchase of the all new SupremeTMTransTube@
Series. This amp represents years of research on vacuum tube emulation, resulting in a totally new Supreme. The preamp has been rede­signed, using patent-applied for technology that redefines tubelike distortion and harmonic generation in solid-state amps.
The new T. Dynamics circuitry, also awaiting several patents, creates the long sought for tube power com­pression phenomenon. This, in combination with resonance and presence circuitry, yields the closest tube amp simulation to date. This compression effect is increased by turning the T. Dynamics control down, which lowers the power level the amp puts out.
To further enhance the performance of the Supreme, an impedance-matching transformer is used to deliver
100
watts into 16, 8, or 4 ohms; and a footswitchable effects loop allows for even greater flexibility.
FRONT PANEL FEATURES POWER SWITCH (1)
Depress the switch to the “on” position. The red LED will illuminate indicating power is being supplied to the unit.
POWER LED (2)
Illuminates when AC power is being supplied to the amp.
T.
DYNAMICS CONTROL (3)
Adjusts the power level of the amplifier from 10% to 100% power. When set to lower settings, the power compression simulation will be much more pronounced.
PRESENCE (4)
An active tone control that boosts the extreme high frequencies by 6
dB.
RESONANCE SWITCH (5)
Used to fine-tune the low frequency range of the speaker enclosure by varying the damping factor of the amplifier between two presets.
EFFECTS LEVEL SWITCH (6)
Selects the effects loop operating level: -10 dBV (0.3 V RMS) when “out” and 0 dBV (1 V RMS) when “in.”
EFFECTS RETURN (7)
Input for returning signals from external low-level effects or signal processing equipment.
3
EFFECTS SEND (8)
Output for supplying signals to external low-level effects or signal processing equipment.
REVERB LEVEL (9)
Controls the overall reverb level.
POST GAIN (10)
Controls the overall volume level of the Lead channel. The final level adjustment should be made after the desired sound has been achieved.
LOW, MID, & HIGH EQ (11,15)
Passive tone controls that regulate the low, mid, and high frequencies for the Lead and Clean channels, respectively.
GAIN SWITCH (12)
Boosts the overall system gain. Depress to the “in” position to activate.
THRASH SWITCH (13)
Notches the mid range about 20
dB.
PRE GAIN (14)
Controls the input volume level of the Lead channel.
CHANNEL SELECT SWITCH (16)
Allows selection of the Lead or Clean channel. The “in” position of the switch selects the Lead channel and the “out” position selects Clean.
NOTE: Channel selection may also be achieved by the remote footswitch. If remote selection is desired, the channel switch must be in the “in” (Lead) position.
BRIGHT SWITCH (17)
Provides a preset boost (6
dB)
to treble frequencies. To activate, depress the switch to its “in” position.
VOLUME (18)
Controls the volume level of the Clean channel.
LOW GAIN INPUT (19)
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 (20)
Used for most electric guitars. It is 6 dB louder than the Low Gain input.

Back Panel:
BACK PANEL FEATURES EXTERNAL SPEAKER JACKS (21)
A
Provided for connection of external speaker cabinet. Minimum external speaker impedance is 8 ohms (4 ohm total impedance).
IMPEDANCE SELECTOR SWITCH (22)
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 ohm enclosures, set switch to 4 ohms).
PREAMP OUT (23)
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.
POWER AMP INPUT (24)
Used to connect line level signal to the power amplifier.
REMOTE SWITCH JACK (25)
Provided for the connection of the supplied remote footswitch. The footswitch is used to select the Lead or Normal channels and defeat effects loop. When using remote footswitch, always insert the plug fully (second click) to insure proper operation.
GROUND SWITCH (26)
Three position rocker-type switch, which, in most applications, should be operated in its center or zero position. There may be some situations when audible hum and/or noise will come from the loudspeaker. If this situation arises, 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) (27)
A
For your safety, we have incorporated a three-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 the proper grounded receptacles.
