ASHDOWN ENGINEERING - AGM
The level of sound or 'volume' you choose to use will mainly be dependent on the size of the
room you are playing in and you should use the volume level that gives you the desired results.
Always operate the amplifier at the lowest level you can in any given situation. Each room will have
a sweet spot. Play at too low a level and the instrument will not react with the amplifier, too high
and the instrument will be unplayable. In all cases you should use a level that you feel comfortable
with. The Human ear is a very sensitive instrument and can easily be permanently damaged by
exposure to the high sound pressure levels that can be produced by this type of amplifier. Do not
operate for prolonged periods of time at high volume without suitable ear protection, or at a level
that causes you discomfort in any way. If you experience any hearing loss or ringing in the ears
Your amplifier is fitted with several fuses to protect yourself and the expensive electronics inside
from damage in the event of a malfunction within the amplifier. The size and rating of the fuses
has been calculated to offer the most protection from damage possible. Various circumstances
can lead to fuse failure. It is recommended that you familiarise yourself with the type and rating
of the individual fuses fitted to your amplifier and carry spare fuses clearly marked with you as
replacements. Occasionally a fuse will fail as a result of a power surge in the supply or as a result
of incorrect connection of the loudspeaker. It is permissible to replace the damaged fuse with one
of the same type and rating as stated on the rear panel of the amplifier, having first unplugged
the amplifier from the mains supply and allowed it to cool down. If the fuse keeps blowing this
indicates that there is a more serious fault within the amplifier such as a damaged tube. In this
event you must take the amplifier to a qualified technician for repair. Never fit a fuse larger than
the recommended rating. The fuses fitted to you amplifier are 'Anti Surge' or 'Slow Blow' or 'Time
delay' type fuses, and have the prefix T or H in the part number. So, for example, a 5 Amp fuse
would be T 5A H. The exact rating for each particular fuse can be found next to the holder in which
that fuse fits. If you are not sure what to buy when purchasing replacements,
