| LDS
is a patent-pending circuit from Sherbourn Technologies designed
for use with multi-channel power amplifiers. This innovative circuit
will allow installers to speedily check the correctness of their
speaker connections without needing an ohm meter or a walk-through.
Today's
installations could have up to eight zones from a single amplifier
- requiring thirty-two speaker connections! It is expensive and
time consuming to check the correctness of those connections. Of
course, in a worst-case scenario, two speaker leads could mistakenly
be cross-connected, causing two amplifier channels to drive against
themselves. If the unit's built-in protection circuit is not active,
then the amplifier may fail, causing aggravation and cost.
The
LDS circuit will initially be included on Sherbourn's new 16/800
sixteen channel amplifier. With the 16/800 connected to the power
supply, the LDS circuit will send a low-voltage probing signal to
check the first zone's connections. A manually-operated rotary switch
housed on the rear panel will allow the other zones to be sequentially
tested, with an LED indicating their status: green for normal, yellow
for open circuit (no coonection), or red for short circuit. Once
all zones have been tested, the LDS switch is placed in its 'off'
position and the amplifier is then ready to play program material.
Sherbourn
Technology's LDS (Load Detection System) is yet another example
of Sherbourn's innovative design technology.
