Features And Innovations - Field Acoustics UK 500 Instruction Manual

1. Features and Innovations

All our amplifiers have been designed to give the best possible performance for their
intended application and are based on our own uncompromising, time proven MOSFET designs.
These take advantage of components which will stand the test of time and give the best possible
performance in a small, exceptionally light weight package.
We only have the desire to provide our users with the best possible solutions and continue to
look for ways to improve upon them.
Amplifier features:
Class AB, MOSFET amplifier topology.
•
.
An unprecedentedly powerful and stable Switch Mode Power Supply.
•
Designed without compromise, to exceed the performance of the previous linear supply
models; whilst offering a weight advantage rarely seen even in other SMPS amplifiers.
.
Soft Start Circuit.
•
The power supply is designed not to draw excessive current on startup - Prevents the
'thump' , as occasionally seen with other equipment, from tripping fuses and breakers.
.
Protection against Short Circuit and Overheating.
•
.
Speaker Protection relay with delay to inhibit switch on thump.
•
The speakers are disconnected during power up/down.
Fully balanced XLR Inputs, which also accept 1/4" jack connectors.
•
.
•
Stereo, Mono and Bridged (Mono) Modes selectable via rear panel switches.
•
Mode of operation indicated on front panel LED status display.
.
In Mono Mode, only input A is used to feed channel pair A and B. Independent
•
control of each channel's output level remains functional.
.
Temperature regulated, High Speed Fan Cooling.
•
A new high speed fan is utilised to ensure maximum reliability by allowing for far greater
cooling latitude (The amplifier vents hot air through rear connector panel).
.
1U Case Format.
•
Compact amplifier format designed to optimise the use of available racking space.
