Footswitch
1. Channel
By connecting the supplied PED801 footswitch to
this jack it is possible to footswitch between Channel
A and Channel B. The footswitch will override the
front panel Channel switch position (item 15).
2. Reverb Footswitch
By connecting another PED801 footswitch
(optional) to this jack it is possible to remotely switch
reverb on and off.
Effects Loop
3. Send
For connection to the input of an external effects
processor.
4. Return
For connection from the output of an external
effects processor.
5. Loop Level
The loop level on the DSL 100 and DSL 50 can be
adjusted to match either floor pedals, requiring a low
level or effects processors which require a high level.
Loudspeaker Outputs
With all valve amplifiers it is imperative that the
amp is connected to a load whilst in operation and
that the impedance selected on the amp matches the
total impedance of the speaker cabinet(s) being used.
Failure to comply with these points will result in
damage to the amplifier.
The DSL 100 and DSL 50 feature three outputs, a
dedicated 16 Ohm output and two outputs selectable
between 4 and 8 Ohms.
The DSL 100 and DSL 50 should not be run into
an impedance less than 4 Ohms.
6. 16 Ohm Output
For the connection of a 16 Ohm speaker cabinet.
It should be noted that when this Speaker Output is in
use the remaining Speaker Outputs, items 7 and 8,
will become inoperational.

7. & 8. 4 & 8 Ohm Outputs
For use when the total impedance of speaker
cabinets used is either 4 or 8 Ohms. That is, when
using either a single 4 Ohm cab, a single 8 Ohm, two
8 Ohm cabs or two 16 Ohm cabs.
9. Impedance Selector
Allows selection of 4 or 8 Ohms impedance for
items 7 & 8.
See Loading Points.
10. Mains fuse
See rear panel for correct value.
11. Mains Input
Your amp is provided with a detachable mains
(power) lead which is connected here. The specific
mains input voltage rating that your amplifier has
been built for is shown on the back panel. Before
connecting for the first time, please ensure that your
amplifier is compatible with your electricity supply.
If you have any doubt, please get advice from a
qualified person. Your Marshall dealer will help in
this respect.
12. H.T. fuse
See rear panel for correct value.
Loading Points
One 4 Ohm cabinet, set to 4 Ohms
One 8 Ohm cabinet, set to 8 Ohms
Two 8 Ohm cabinets, set to 4 Ohms
Two 16 Ohm cabinets, set to 8 Ohms
N.B. Always ensure that proper speaker leads are
used to connect speakers to the DSL 100 and DSL 50,
not guitar leads!
WARNING !
WARNING : RISK OF HAZARDOUS ENERGY!
AVIS : ENERGIE ELECTRIQUE DANGEREUSE!
If loudspeaker is disconnected a high voltage can
be present at these output terminals. Operation in this
manner can damage your amplifier, therefore ensure
that loudspeaker is properly connected.
Your amp should be completely powered down
before changing loads.
