Sherbourn Technologies TST-200.4 Brochure

CUSTOM SOLUTIONS

Similar to the TST2/200, this smooth and
articulate 200 watt amplifier uses Thermal
Shift Technology™ for driving multiple
pairs of speakers. 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
saturate a volume control. Four pairs of
speaker connectors are linked to four zone
buttons to negate the need for a cumber­some speaker selection box. Optional rack

mount ears are available. TST 200-4
includes patent-pending circuitry that auto­matically checks for short circuits and
measures the intended impedance load to
enhance long term reliability.

This is a product for consumers who want
the same music in different rooms in the
house but still want musical fidelity.

Introducing an innovative two-channel amplifier with
Thermal Shift Technology™ that drives multiple pairs of
speakers with effortless efficiency: Model TST200-4.

FEATURES AND SPECIFICATIONS: TST200-4

• 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 conent 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
