Marshall ASTORIA CLASSIC Manual Del Usuario página 2

INTRODUCTION
Thank you for choosing Marshall and congratulations on the purchase of your British
made, all-valve, 30 Watt Astoria Classic AST1C combo or AST1H head. Our goal with
the Astoria Classic was simple: create a single channel amplifier with the purity of
hand wired clean valve sound, classic tonal function and contemporary switching.
We sincerely hope that your Astoria Classic will provide you with countless hours of
tone.
OVERVIEW
Your Astoria Classic has been expertly
crafted and is designed, engineered and
constructed to the highest possible
standards at the Marshall factory in
Bletchley, England. Its all-valve heart
comprises of: 3 x ECC83 (12AX7) in the
preamp, a GZ34 rectifier, and 2 x KT66
in the output stage, which is cathode
biased with no negative feedback. This
is a characteristic of many classic,
vintage amplifiers.
The Astoria Classic combines a 100%
hand wired signal path with modern
Power Reduction. To achieve this
innovative marriage of authentic tonal
character and contemporary switching
capability the Astoria Classic uses
turrets mounted on the PCB – allowing
the hand wiring and the more complex
switching circuitry to elegantly co-exist
on a single board.
The Sensitivity control adjusts negative
feedback in the preamp, and the Edge
control determines how bright or dark
the amplifier sounds overall. To further
enhance your tonal palette, the front

panel Power Reduction pull switch drops
output power from 30 Watts to 5 Watts,
producing warmer, softer tones.
The Astoria Classic will appeal to purists
who want authentic clean all-valve
tone, and to boutique pedal enthusiasts
who will find it the perfect pure-valve
foundation for their sound.
The Astoria Classic combo features a
12" custom-voiced Celestion Creamback
speaker, as does the optional AST1-112
speaker cabinet, which is designed to
match either the AST1H head, or the
AST1C combo as an extension speaker
cabinet.
WARNING! IMPORTANT SAFETY INSTRUCTIONS
WARNING:
Before going any further, make sure that
your amplifier is compatible with your
mains electricity supply. If you have any
doubt, please seek help from a qualified
technician – your Marshall dealer can
help you in this respect.
MAINS INPUT & FUSE:
The specific mains input voltage
rating that your amplifier has been
manufactured for is indicated on the
rear panel of the amplifier.
Your amplifier is provided with a
detachable mains (power) lead, which
should be connected to the MAINS
INPUT socket on the rear panel of the
amplifier.
The correct value and type of mains
fuse is specified on the rear panel of the
amplifier.
NEVER attempt to bypass the fuse or fit
one of the incorrect value or type.
TRANSPORTING YOUR EQUIPMENT:
Please ensure that your amplifier is
switched off, unplugged from the mains
electricity supply and all removable
cables have been disconnected from
your equipment before attempting to
move it.
IMPORTANT SET UP INFORMATION:
1. Make sure that the speaker or
speaker cabinet(s) is connected to
the correct impedance loudspeaker
jack socket(s) on the rear panel of
the amplifier. See the
LOUDSPEAKERS guide in this
manual (Rear Panel Functions #3)
for specific information regarding
impedance matching. When using a
speaker cabinet(s) make sure that
you use a proper speaker cable.
Never use a screened (shielded)
guitar cable for this purpose.
NOTE: Before connecting or
disconnecting speakers you MUST
switch the amplifier off and
disconnect it from the mains
electricity supply. Switching on
without a speaker or speaker
cabinet(s) plugged in will damage the
amplifier.

control on the front panel is set to
zero (Front Panel Function #2).
3. Connect the supplied mains (power)
lead into the MAINS INPUT on the
rear panel first and then into the
mains electricity supply. (Rear Panel
Function #1)
4. Plug your guitar into either the HI or
LO input jack socket on the front
panel (Front Panel Function #1).
5. Turn the front panel power switch
ON (Front Panel Function #10) and
wait for a few minutes before going
to point #6 below.
6. After waiting, engage the STANDBY
switch (Front Panel Function #9).
7. Turn the MASTER volume up to your
preferred level and your amp is ready
to play.
