Bi-Channel

Tube

& Solid-State Amplifiers

OPERATING - SERVICING MANUAL

The VTX and STXTube and Solid-State Bi-Channel Amps have been engineered to provide the guitarist with a maximum

of control capability and a minimum of complexity. Two independent and identical channels, each feature continuouly

variable Preamp Drives, produce outputs ranging from a clean, undistorted output to a heavy Harmonic Sustain output.

Master Volumes allow independent level control, and seperate Reverb and Graphic EQ circuitry contribute to an almost

infinite variety of accoustic control.

Advantages of the Carvin Bi-Channel Amp: (1)Separate Channels for Bass and Treble guitar pickups (providing astereo

guitar is used). (2) Switching Channels for instant tone changes. (3) Clean to Distortion Channel Switching. (4) Switching

for instant soft to loud volume changes for either clean or sustain output. (5)Double sustain or clean volume levels when

both channels are switched on. (6) Use as a BiAmp system when other components are added.

Other Bi-Channel Amp features include a fully balanced 600 Ohm Line Output for recording plus separate Channel

Interrupt Jacks for each channel.

The Bi-Channel Tube and Solid-State Amps are available in a variety of models depending upon the speakers ordered.

See the Carvin Equipment Catalog for exact model numbers.

The top jack is the input to Channel 1 while the bottom jack feeds Channel 2. The center jack allows one instrument to be fed into both channels simultaneously. Note that the center jack is active only when the other two jacks are unused. 2.

l o o o REAR PANEL 1. FUSE HOLDER Access to the fuse can be gained by pushing the fuse-holder inwards, then turning counterclockwise. The type of fuse to be used is printed just below the fuse-holder. Should the fuse ever fail, replace it with an identical fuse. If the second fuse fails, then a problem is indicated, and the amp should be serviced. To prevent unnecessary damage to the amplifier, NEVER USE A FUSE WITH A HIGHER RATING. 2.

81 AMPING 81 AMP THEORY Bi Amping is accomplished by dividing electronically the audio spectrum into two parts. One amplifier and speakers handles the Lo Frequencies (Lo Pass) while another amplifier handles the Hi Frequencies (Hi Pass). Advantages of Bi Amping are: (1) Lower distortion because the low frequencies do not distort the high frequencies. (2) Twice the volume levels when using the same equivalent RMS power.
