Thank you for choosing an Ashdown Valve Series ampliļ¬er. To ensure
that you receive the full beneļ¬ts of the Ashdown warranty, please
register your ampliļ¬er at www.ashdownmusic.com
WARRANTY
Your ampliļ¬er is covered by a one year warranty, against defects in
materials and workmanship, for the original purchaser. Ashdown will, at
their discretion, replace or repair any product or part thereof, which is
found by Ashdown to be defective. This warranty shall not apply to the
damage of covering, ļ¬ttings or ļ¬nishes when affected by carelessness,
accident or extreme climate changes. Nor does it apply to normal wear
and tear of parts such as valves, fuses, light bulbs, speakers, controls etc.
In the unlikely event of any defect, please contact an authorised
Ashdown dealer. All transport charges are to be pre-paid by the Owner.
Unless your purchase is registered on-line, normal country warranty laws
apply.
IMPORTANT SAFETY INSTRUCTIONS
This Ashdown ampliļ¬er has been designed to provide you with many
years of faithful service ā€“ 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 ampliļ¬ers 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 ampliļ¬er, run through the check list below. If you are
in any doubt about any aspect of the ampliļ¬erā€™s operation, stop using
it immediately and do not resume operation until the ampliļ¬er has been
thoroughly inspected by a qualiļ¬ed technician.
1) Storage and moving
When your ampliļ¬er is not in use make sure that the power cord
is unplugged from the mains outlet, and that all leads are removed
from the ampliļ¬er, 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 ampliļ¬er 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 ampliļ¬er 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 ampliļ¬er from a hot
humid place (such as a nightclub) to a cold place (like a motor vehicle).
In such instances, always move the ampliļ¬er into a warm dry room to
prevent damage.
When moving the ampliļ¬er, handle it as carefully as you would your
instruments. Although solidly built, an ampliļ¬er 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 ļ¬nish and, if you are transporting it with
other equipment, make sure that the ampliļ¬er is on a solid ļ¬‚oor at the
bottom of the pile.
Ampliļ¬ers are heavy. Take care when lifting, always use the handles
ļ¬tted to the ampliļ¬er to move it, and get help if you have to lift the
ampliļ¬er to a greater height than you feel comfortable with.
Never attempt to operate the ampliļ¬er after it has been dropped. Take it
to a qualiļ¬ed technician and have it checked before using it again.
2) Leads and plugs
Your ampliļ¬er 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 ļ¬t your mains outlet consult your dealer or a qualiļ¬ed electrician
for advice before attempting to use the ampliļ¬er.
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 ļ¬rst
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 ļ¬tted to the cord.
When using your ampliļ¬er 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 ampliļ¬er for damage before use. Check each lead for
damage before you plug them in to the ampliļ¬er, and ensure that the
loudspeaker is connected before you switch the ampliļ¬er on.
Never try to operate the ampliļ¬er without the speaker connected. If
you do, serious damage to the ampliļ¬er will result which will be very
expensive to repair.
Double check the connections you have made to your ampliļ¬er 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 afļ¬xed to the back of the
cabinet, so if the cabinet is 16R (Ohms) then you plug into the 16R outlet
on the ampliļ¬er.
4) Using the ampliļ¬er
When you set the ampliļ¬er up for use, it is important that you adhere to
the following rules:
Place the ampliļ¬er away from sources of heat, including radiators, etc.
The ampliļ¬er itself will get hot in normal use.
Make sure that all the grilles on the ampliļ¬er are not obstructed in any
way so that cooling air can circulate through the ampliļ¬er. Do not place
anything on or behind the ampliļ¬er that might restrict the ļ¬‚ow of air. This
includes items of clothing, or other equipment.

FRONT PANEL FACILITIES
INPUTS - There are two instrument inputs marked LOW and HIGH. The LOW input is highly sensitivity and also high
impedance to suit the output from PASSIVE (Low Output) basses - The HIGH input is low sensitivity and lower impedance to
suit the output from ACTIVE (High Output) basses. Plugging an active (High Output) bass into the LOW input will overload the
input, creating a fatter, warmer and more distorted sound. Experiment by plugging your bass into either input to achieve the
desired sound.
EFFECTS SEND AND RETURN - These 1/4ā€ jack sockets should be used to connect to an external effects device or pedal board.
The EFFECTS SEND output should connect to the INPUT of the effects unit, and the output of the effects unit should be connected
to the EFFECTS RETURN input.
EQ CONTROLS - Use the MIDDLE, BASS and TREBLE controls to effect the overall tone of the sound. The MID SHIFT switch
causes the MIDDLE control to operate on higher frequencies in the up position, and lower frequencies in the down position.
The BASS SHIFT switch causes the BASS control to operate on deeper frequencies in the up position, and less deep frequencies
in the down position. The BRIGHT switch adds an overall brightness to the sound when in the up position. (Note: The BRIGHT
switch is not effective when the GAIN control is set to full).
GAIN - This controls the level of the signal sent to the MASTER section. To achieve a cleaner sound, turn the GAIN control down
and the MASTER up. To achieve a richer, more distorted sound, turn the GAIN control up and the MASTER down.
MASTER - This controls the overall output of the ampliļ¬er.
MUTE - In the in position, this switch mutes the out put of the ampliļ¬er (useful for tuning, etc.).
PRE/POST - This switch determines whether the signal from the DI OUTPUT is taken before/PRE the EQ section (in position) or
after/POST (out position).
VU METER - The VU meter provides a visual indication of the output level of the ampliļ¬er. It also acts as a bias meter, please
see the following page for more details.
REAR PANEL FACILITIES
SPEAKER OUTPUTS - There are dedicated Speakon connectors for 2, 4 and 8! load speaker cabinet conļ¬gurations. It is
important that the correct output or outputs are used to match the impedance load of your cabinets. Please refer to the
diagrams later in this manual.
