INTRODUCTION
The HH V800 MOS-FET Power Amplifier is designed for heavy duty continuous operation at high power levels.
This rugged HH amplifier will tolerate a good deal of electrical abuse, output short circuits and load mismatch
without causing harm to the MOS-FET devices. This makes the V800 ideal for a wide range of applications from
recording and broadcasting to live performance and state of the art home sound systems.
The V800 Power Amplifier incorporates design features which eliminate the problems of secondary breakdown,
thermal runaway, elaborate protection circuits and measurable transient intermodulation distortion.
The front panel includes a 10 segment LED level meter, as well as independent left and right precision detented
input attenuators. Also present are the mains power switch and LED indicators for the thermal protection circuit
and internally switched Bridged (Mono) mode.
The rear panel contains the units input and output connections, as well as an IEC mains power supply inlet.
This manual contains important information on operating your amplifier correctly and safely. Please take some
time to read this manual to familiarise yourself with the advanced features of this amplifier.
Unpacking
Inspect the amplifier during unpacking, if any damage is found, notify the dealer you purchased it from immediately.
Be sure to save the carton and all packaging materials. Should you ever need to return the unit back to the dealer
or HH Electronics, use only the original factory packing.
Installation
HH professional amplifiers are designed for durability in commercial installations and provide the quality
performance required in studio and live performance applications. The V800 is 4U rack height, with 384mm depth,
designed to mount in a standard EIA 19" rack. When using the equipment in a rack, consideration should also be
given to cooling. The air flow through the unit from front to back should not be obstructed or hindered in any way,
so adequate ventilation in the front and rear of the rack cabinet is important.
The V800 can also be used standalone using the supplied rubber feet and screws.
Basic Setup
Rack mount the amplifier in the location where it is to be used, with consideration to accessibility, cooling etc.
Make all the connections to the input connectors on the desired channels. Connect speaker cabinets to the
required output connectors, paying attention to the impedance and phase.
With the power switch OFF and both attenuator controls set in their lowest position (-¥
dB), connect the mains
power cord to the amplifier, then to a suitable electrical source to allow proper current draw. The amplifier is now
electrified and on standby status, there is no indication on the amplifier that there is power connected.
Turn ON the power switch, now the attenuator controls can be raised slowly to the desired settings. It is
recommended that gain levels are controlled from the signal source, rather than using the attenuator controls.
Initially the control can be set to maximum (0dB), and adjusted if the input signal is too hot.
Switching Off
After using the amplifier, please adjust the attenuator controls to their lowest settings (-¥
dB) or ensure the input
signal is at 0, then the amplifier can be turned off safely. Turn the power switch to the OFF position and remove the
power cord from the electrical source.
NOTE:
Do not connect or disconnect from the input signal source when the amplifier is turned ON, damage could occur
to the amplifier and the speaker.
