A-Series amplifiers are not only suitable for use in both heavy duty touring
sound reinforcement systems but also when high headroom and low distortion are
needed to fully reproduce the dynamic range and clarity of today’s digital
recordings. They are built to survive grueling road conditions and will drive
reactive phase shifted loads with no difficulty - even though they are fully
protected from accidental short circuits. Unlike many of our competitors,
Yorkville power amplifiers are designed for rock solid performance right down
to and below their lowest impedance ratings. This impedance aware strategy
deals with the realities of driving typical reactive speaker loads and the
associated problems such as thermal shut-down, inductive ‘snap-back’, and
premature current limiting.
All A-Series amplifiers undergo a thorough computer-monitored,
temperature-cycled, burn-in period to test for any deviation from design
parameters. The designs, while unique, are conservative with regard to the
power handling capabilities of the output devices. The computer optimized heat
dissipation system ensures that excessive thermal stress will not occur. Cool,
clean air is supplied to the amplifier via fan-assisted front-to-rear venting.
A user-serviceable filter is incorporated into the front mounted air intake
grill, ensuring long-term reliability. Front panel Power, Protect, Activity and
Clip LED's are bright and easy to see and all knobs and handles are recessed
for safe, easy transportation. All A-Series power amplifiers also feature full
DC, load and thermal protection while a user-defeatable limiter maintains full
output without audible clipping.
The back panel features Speakon™ and binding post outputs as well as balanced
XLR & ¼" TRS inputs. The peak limiter, subsonic filter, mono/stereo/bridge
mode and ground lift switches are also mounted on the back panel.
