TH-Cross

HEAD type bass amplifier with both tube and transistor preamps and double power amp, working in BIAMP, STEREO or MONO modes. The switchable mode enables wide range of speaker cabinets to connect varying in impedance from 2 to 16 Ohm and handling power from 200 up to 750W. The amplifier uses a very efficient and at the same time easy to operate MLO system equalization control for fast and accurate sound tailoring. Unique OPTICAL LIMITER is built in for fast and noiseless operation. Possibility to “cross” the amplifier with an additional preamp. Connecting an external preamp creates a configuration of 2 selectable independent channels. The use of additional preamp brings a wide range of new sound creation opportunities: 2 identical panels with separate input control, tone, limiter and volume. Preferred tone shape, input sensitivity, tube saturation, volume and compression can be set for each channel independently and switched between the channels while playing. Also an external sound effect can be connected to each of the channels. A specially designed TAURUS TX-Cross dedicated preamp is used to create the stereo system.

Power output: 750W RMS / 4ohm , 200W RMS / 8ohm
Operation modes:
MONO: 750W RMS /4 ohm, 700W RMS /6ohm, 600W RMS /8ohm, 400W RMS /16ohm
BIAMP/STEREO: 2x375W RMS /2ohm, 2x300W RMS /4ohm, 2x250W RMS /6ohm, 2x200W RMS /8ohm

Main features: 2 preamps - tube and transistors / analog device
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
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
