TX-Cross

Both tube and transistor bass PREAMP built to work with any amplifier but dedicated to cooperate with TH-Cross bass head amplifier. The PREAMP and an amplifier can be “crossed” in 2 ways: 2-channel or stereo. Connecting the TX-Cross PREAMP with the TH-Cross amplifier brings a wide range of new sound creation opportunities: 2 identical panels with separate input control, tone, limiter and volume. A musician can set preferred tone shape, input sensitivity, tube saturation, volume and compression for each channel independently and switch between the channels while playing. Also an external sound effect can be connected to each of the channels. In stereo configuration we get a fully stereophonic system with independent control panel for each channel, stereo effect loop and with stereophonic sound transmission effected through 2 line outputs. The PREAMP uses a very efficient and at the same time easy to operate BOX ELECTRONICS’ own unique MLO equalization control for fast and accurate sound tailoring. Unique high quality OPTICAL LIMITER is built in for fast and noiseless operation.

The TX-Cross PREAMP can operate with any power amplifier. Coupling it with another preamp opens new possibility: a 2-channel system foot switchable between the preamps.

2 preamps / tube and transistors /
Two channel mode - 1 internal channel + 1 external channel used to connect a separate preamp channels selected by FOOT SWITCH
Inputs:  passive & active

Controls:  
BALANCE  control between the power amps
GAIN  control with overload indicator. Operating with Gain and Input Mix player can obtain sound very close to acoustic bass or fretless bass guitar. The area around knobs marked by a break-off line indicates the region where the level of compression and distortion allows achieving the desired effect.
MIX  fluent signal adjustment of the input between 2 sections of the amplifier - tubes simulation and transistors.
COMPRESSOR/LIMITER to control dynamic of sound

Tone:
VOLUME  control
BASS and TREBLE equalizer with "MLO system" (Middle-range Level Optimization).
PARAMETRIC EQUALIZER for precise control of middle range (120Hz-4kHz)
PRESENCE  button - increases transparency of sound
PUNCH  button - increases sonic expression
DBS - Dynamic Bass System, increases dynamics and selectivity of bass sound

Other features:
MUTE  button
PEAK  preamp overload indicator
FOOT SWITCH input (switches the additional preamp connected to AUX-2)
STEREO MODE input for dedicated TAURUS TX-Cross preamp

Effect loops: AUX for serial and parallel configuration
CROSS LOOP parallel for external preamp with FOOT SWITCH selectable internal and external channels
Outputs:  XLR (balanced) LINE output with level control, speaker cabinet simulation, PRE/POST
switch and GROUND LIFT circuit switch, PREAMP OUT, TUNER, PHONES, SPEAKER

Dimensions:  19” / 2 Rackspaces (H x W x D) 88x483x140 mm
Weight:  3,3 kg
