16-Channel Amplifier
The elegant rack-mountable
LDS 16/45 16-channel amplifier offers up to 75 watts of smooth, articulate
power from each of eight zones. Included on the rear panel
are RCA inputs for eight zones and a bussing system when zones share
the same input, plus music signal sensing switches, gain controls,
stereo/mono/bridging switches, 12 volt triggers and eight pairs of
speaker connectors. Each zone can drive two pairs of eight ohm or
one pair of four ohm speakers. Inside the chassis are thirty two
discrete output devices, two hefty 775VA toroidal transformers and
eight large heat-sinks for truly efficient fan-free cooling. The
LDS 16/45 includes Sherbourn’s patent pending circuitry which
checks each zone for short circuits and then measures the intended
load’s impedance to enhance long term reliability. Sherbourn’s
worldwide reputation for performance, value and reliability is further
advanced with this remarkable and versatile amplifier.
Compared to the 16-40 the 16-45 includes new and more robust discrete output devices that give an increase in power to 45/75 watts per channel into 8/4 ohms respectively – all channels driven.
 Features
- Full-width
four inch high rack-mountable chassis
- Elegantly
sculptured front panel has a master power switch with blue
LED
- Total
of thirty-two discrete output devices
- Two hefty
775 VA quadruple tapped dual voltage transformers so that
each zone is allocated
its own specific share of
the transformers to ensure that all channels will have identical output capability
- Eight
large aluminum heat-sinks for a cool fan-free operation
- Outputs
45/75 watts per zone into 8/4 ohms respectively with all
channels driven
- Rear panel
includes RCA inputs, a simple bus system for use when adjacent
zones will have the same
music, gain controls,
stereo/mono switches, 12 volt triggers and eight sets of removable speaker
connectors
- Removable
power cord
- Patent-pending
circuitry that will automatically check for short circuits
and then measure the impedance of
the intended speaker load before connecting it to the amplifier. This test
of impedance
helps to ensure that the load is within the
required specification and so will not cause excessive distortion, overheating
or long-term
reliability problems
