INH™ Lightweight Amp Instruction Manual
Product Overview
Install ‘N’ Hire Amplifiers meet and exceed needs of both professional Fixed Installations and
Audio Equipment Hire. In an Installation, top performance, reliability and features are a must.
When you Hire you need all this in a robust and portable package. Good job INH Lightweight
Amplifers can survive rough handling on a daily basis.
As the signal processing element of the Install ‘N’ Hire range, Lightweight Power Amplifiers
are designed to get the best from speakers and subs in the rest of the range. Current and
output settings are finely balanced for the unique acoustic profile of INH Plywood and Portable
speakers, ensuring an unsurpassed performance every time. Amplifiers will be run day in,
day out and mainly at high volumes. So, exacting build standards are a must. With INH
Lightweight Amplifers, no compromise is made on design, and only the best components are
used for maximum life. Unique protection circuitry ensure that they withstand even the harshest
conditions.
A number of safety features are integrated into each INH™ Lightweight Amplifier. These protect
the amplifier itself and any other audio equipment that may be connected to it. In particular
• Temperature control circuits ensure operation up to 90°C. At this point a thermal shut-off
protects the unit until the temperature drops to 88°C. During operation, fan speed will vary to
maintain a stable internal temparature and it is normal to hear this.
• Speaker damage is prevented if an overload is detected by automatically removing clipping.
• Anti-surge circuits are fitted to compensate for power spikes that may occur during start up
and shut-down.

INH™ Lightweight Amp Instruction Manual
For your Safety
• Follow all instructions to maintain Manufacturer Warranty and for your own safety.
• There are no user replacement parts inside the product. Do not open the product for any reason.
This will invalidate your Manufacturer Warranty and may cause you harm.
• Do not expose this product to moisture, rain or other fluids.
• Do not use this product near water or other fluids.
• Do not use if the product if you suspect it has been damaged in any way, including being dropped,
is malfunctioning, or has been exposed to liquids or moisture. The unit must be repaired by an
authorised service centre only. Manufacturer Warranty is void if unit is opened or adapted in any
way. Operator safety may be compromised if this product is not operated and maintained in
accordance with the details contained in this Instruction Manual.
• This appliance must be earthed. Do not remove the earth connection in the plug or any other
location- it is essential for user safety.
• Be aware that products are mains powered and may be capable of producing high voltages from
their outputs and have mains voltages inside cabinets.
Product Installation, Use & Maintenance
• Keep this Instruction Manual safe for future reference.
• Clean the product housing with a clean and dry, non-abrasive cloth. Do not use solvents or
liquids to clean the product. Pay particular attention to the lens since this will require cleaning on
a weekly basis to remove any oil residue that may have built up.
• To prevent overheating, do not obstruct any ventilation opening, fan cover or vent. Do not stack
other items on top of the unit. Provide at least 200mm of clear space around any ventilation
holes and ensure no flammable items are nearby.
• Avoid repeated or rapid powering up or shutting down of the unit.
• Power connection to the product is via a UK 240 Volt AC three-pin mains plug. Do not remove or
adapt this plug. If necessary, only replace a fuse with one of the same type, size and value.
• The mains lead must not be crushed or damaged. If any damage occurs, disconnect from
the mains immediately. Replace the damaged cable, or if the mains lead is captive, return the
product to an authorised repair centre for cable replacement. Do not attempt to repair the cable
- it must be discarded and destroyed.
• To maintain the Manufacturer Warranty, only attach authorised accessories and external devices.
This includes cables, connectors and other electrical and/or mechanical devices.
• Unplug the product from the mains during lightning storms or periods of mains fluctuations. If
the product is going to be unused for long periods, unplug from the mains.
• A very strong magnetic field is generated during operation. This can introduce “hum” into nearby
unshielded equipment and damage sensitive magnetic media. We recommend mounting the
unit at the foot of any rack and use of grounded and floating earth settings.
