2CH Amplifier with Thermal Shift Technology™

The TST 200-4 is a slim, 1U high amplifier that defies its small size. Outputting 100 watts for each of its stereo channels, the TST 200-4 can easily drive four pairs of 8-ohm speakers in up to four zones thanks to its Thermal Shift Technology™. Each zone can be selected separately from the independent front panel buttons. No more need for a cumbersome speaker selector box.

The rear panel includes XLR and RCA inputs, a 12-volt trigger input, signal sensing switches, gain controls, a stereo/mono switch and a subsonic filter for removing low frequency noise that may cause saturation.

Optional rack mounting hardware is available for those who choose to include the amp in a custom application.

Features

Full-width chassis with optional racks available
Sculptured front panel has a master power switch and four “zone” buttons
Ten discrete power transistors
Two large 200 VA toroidal transformers
Two large heat-sinks for fan-free cooling
Uses “Thermal Shift Technology” that allows loads down to two ohms without causing excessive distortion or overheating
Comfortably drives up to four pairs of eight ohm or two pairs of four ohm loudspeakers
Includes four sets of speaker outputs that are linked to four “zone” buttons so no separate speaker selection box is required
Rear panel includes XLR and RCA inputs, a 12 volt trigger, gain controls, a stereo/mono switch, and a sub-sonic filter for rolling off unwanted low frequency current if transformer type volume controls are used
Includes Sherbourn’s patent pending LDS circuitry that automatically checks for short circuits and which measures the intended impedance load before connecting the load to the amplifier
Warranted three years for parts and labor
