Thank you for purchasing a Tannoy power amplifier. This manual contains important information on operating your amplifier correctly and safely.
Please take some time and read this manual to familiarize yourself with the advanced features of this amplifier.
Carefully open the shipping carton and check for any noticeable damage. Every Tannoy amplifier is tested and inspected before leaving the factory
and should arrive in perfect condition. If found to be damaged, notify the shipping company immediately. Only the consignee may institute a claim
with the carrier for damage incurred during shipping. Be sure to save the carton and packing materials for the carriers inspection.
It is also advisable to save the carton and packing material, even if the amplifier is undamaged. Should you ever need to ship the amplifier, always
use original packaging.
