Marshall Amplification DRP-1 - Manual (Page 4)

8. Battery Level LED.
When activated by the switch (Item 7) the
LED will illuminate when there is sufficient
battery power to run the DRP-1.
Low battery levels will produce no light from
the LED, whilst borderline power will produce
only a dim output.
Rear Panel.
9. Input Jack.
Accepts the input from the guitar.
10. D.C. Input.
Accepts 9V DC power from a regulated
power supply.
11. Pre-amp Out jack.
A buffered output suitable for feeding a ‘live’
guitar system such as a separate power amp and
guitar speaker cabinet set-up.
12. Line Out Jack.
Provides the output from the ‘power amp/
loud speaker emulator’.This output should be used
when wanting to directly record a full guitar amp
simulation.
The Line Out socket would also be used to
feed the input of your effects processor when
using the DRP-1 for private practice through the
headphone amplifier, or to feed the input of a
normal guitar amp/ combo as an additional pre-
amp.
13. Headphone Amp Input Jack.
A stereo jack accessing the input to the
headphone amplifier which allows the insertion of
effects processors between the headphone amp
and the output of the emulator.
By connecting the left and the right outputs of
the processor to this socket using a stereo jack to
two mono jack Y lead, you can gain all the
benefits of your favourite effects through the
stereo headphones connected to socket 14.
14. Headphone Amp Output Jack.
A stereo 3.5 mm jack fed from the integrated
headphone amp, which will suit stereo headphones
from 32 to 600 Ohm impedance, for private
practice.
To maximise the life of the battery, the
headphone amp is only provided with power when
the headphones are fully connected to the socket.
To prevent the switching transient being
passed onto other externally connected equipment,
any channel faders etc. should be down when
inserting the headphone jack.
Note!
Due to the widely varying nature of
headphones, undesired clipping of the headphone
amplifier may occur and will produce harsh
distortion.
To control this simply reduce the line level
until a satisfactory tone is achieved.
15. Battery Compartment (Located in
the base of the unit).
Finger removable cover gives easy access to
the battery compartment for the 9V PP3 or
equivalent type battery.
Note!
The power to the DRP-1 is controlled by the
guitar input jack, therefore to preserve the battery
life the guitar lead should be removed when the
unit is not in use.
Using an external power supply will switch
out the battery, but the DRP-1 is still turned on/off
by the guitar input jack.
When unplugging the input jack, it is a wise
precaution to turn down any mixer or recorder
level controls to prevent any handling noise being
passed onto external equipment.
