XPRO™ Power Amp Instruction Manual
Product Overview
Perfect companions to the Brooke XPRO™ range of Multi Purpose cabinets, Brooke XPRO™ Power
Amplifiers feature the large power reservoirs and high currents required by more demanding
audio equipment. Suitable for rackmount or table-top use, integrated lifting handles assist with
transport and fitting.
A number of safety features are integrated into each XPRO™ Power 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.

XPRO™ Power 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.
