Innovative
2CH Amplifier with Thermal Shift Technology™
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 rackmount ears are available.
The 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.
 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
