IMPORTANT SAFETY INSTRUCTIONS

This Ashdown amplifier has been designed to provide you with many

years of faithful service – on the road, in a studio or in a domestic

environment. By following the rules set out below, you will ensure

that the unit functions safely.

Valve (tube) instrument amplifiers contain very high voltages and fragile

glass tubes and should therefore be handled with care. A number of

important precautions which must be observed are set out below.

Before using the amplifier, run through the check list below. If you are

in any doubt about any aspect of the amplifier's operation, stop using

it immediately and do not resume operation until the amplifier has been

thoroughly inspected by a qualified technician.

1) Storage and moving

When your amplifier is not in use make sure that the power cord

is unplugged from the mains outlet, and that all leads are removed

from the amplifier, including jack leads and footswitch leads. Jack

socket connectors are self-cleaning, so the process of plugging in

and unplugging the leads when not in use will ensure that the internal

contacts will be cleaned when you plug in again.

Store your amplifier in a warm, dry place away from moisture and

condensation. A motor vehicle or cellar may look dry but condensation

can form inside the unit causing short circuits and possible electric shock.

If you suspect the amplifier may have become exposed to moisture,

move it to a warm dry place and leave it to dry out for at least 48 hours

before attempting to use it.

Condensation can also occur when you move the amplifier from a hot

humid place (such as a nightclub) to a cold place (like a motor vehicle).

In such instances, always move the amplifier into a warm dry room to

prevent damage.

When moving the amplifier, handle it as carefully as you would your

instruments. Although solidly built, an amplifier is easily damaged

by shock, so be careful not to drop it or allow it to fall over. Use a

protective cover to protect the finish and, if you are transporting it with

other equipment, make sure that the amplifier is on a solid floor at the

bottom of the pile.

USER MANUAL

CTM 300 / CTM 100

Amplifiers are heavy. Take care when lifting, always use the handles

fitted to the amplifier to move it, and get help if you have to lift the

amplifier to a greater height than you feel comfortable with.

Never attempt to operate the amplifier after it has been dropped. Take it

to a qualified technician and have it checked before using it again.

2) Leads and plugs

Your amplifier contains possibly lethal voltages and must therefore be

connected to the mains using the correct power cord, which is a three

terminal type with a ground connection.

The power cord supplied with the unit should be of the correct type. If it

does not fit your mains outlet consult your dealer or a qualified electrician

for advice before attempting to use the amplifier.

Never modify the power cord or attempt to use it with a two pin outlet.

Store all your leads in a dry case and take care when packing them

away. All leads, including guitar leads, are easily damaged with

careless handling, so it is a good idea to carry a spare lead of every

type you use. Flexible power cords get damaged very easily. At the first

sign of damage, discard it and purchase a new one. Always replace

the power cord with one of the same type. Moulded cords are the best

choice with both plugs permanently fitted to the cord.

When using your amplifier and other equipment it is a good idea to

connect to the supply using a unit known as an R.C.D. These units are

not expensive and offer the user additional protection against electric

shock. An electrical shop should be able to supply you with a suitable

unit.

3) Before Use

Inspect your amplifier for damage before use. Check each lead for

damage before you plug them in to the amplifier, and ensure that the

loudspeaker is connected before you switch the amplifier on.

Never try to operate the amplifier without the speaker connected. If

you do, serious damage to the amplifier will result which will be very

expensive to repair.

Double check the connections you have made to your amplifier and

make sure you have connected the speaker to the correct outlet socket

that matches the cabinet you are using. The impedance of the speaker

is important and is usually shown on a plate affixed to the back of the

cabinet, so if the cabinet is 16R (Ohms) then you plug into the 16R outlet

on the amplifier.

4) Using the amplifier

When you set the amplifier up for use, it is important that you adhere to

the following rules:

Place the amplifier away from sources of heat, including radiators, etc.

The amplifier itself will get hot in normal use.

Make sure that all the grilles on the amplifier are not obstructed in any

way so that cooling air can circulate through the amplifier. Do not place

anything on or behind the amplifier that might restrict the flow of air. This

includes items of clothing, or other equipment.

Do not place the amplifier in such a position where it may get splashed

with liquid or water, e.g. near tables of drinks or near equipment that

contains water, e.g. smoke and bubble machines.

Never stand bottles or containers of liquid on the amplifier. If any

liquid is accidentally spilled into the amplifier, unplug it from the mains

supply immediately and take the amplifier to a qualified technician for

inspection.

Do not place objects on the amplifier that could fall inside and cause a

malfunction, e.g. coins, tools, etc.

5) Sound level

The level of sound or 'volume' you choose to use will mainly be

dependant 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 you should

consult a doctor or audiologist.

6) Fuses and ratings

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, take the

amplifier with you and show the rear panel to the retailer.
