Award Session JD10 MK2.3 User manual

Additional Information
PLEASE READ THIS BEFORE CONTACTING US!
Male XLR Output - The XLR chassis plug
provided will mate with any standard microphone
cable wired for ‘balanced’ signals. The signal
available is an un-balanced signal, but is equal in
quality to that of a balanced line. It is identical to
to that appearing on the JACK output, tip
connection - so there is no difference or benefit to
using one output over the other, except that of
convenience.
XLR Output Pin Connections - The signal appearing in PIN 2 is IN PHASE with the signal appearing on
the TIP contact of the JACK output.
Note to our American customers:
The JD10 you have just bought is an updated version of the JD10 formerly available under the MORLEY
brand. The differences are: New distortion circuitry, a balanced volume level between Classic & Rock gain
settings, silent FET switching, a male XLR output connector and new artwork to the facia.

About This Latest JD10 Version 2.3
Great at on-the-edge blues to full-on scooped metal, the JD10 2.3 pedal is
a re-created version of the famous direct recording preamp/pedal first
introduced in 1995, but has been specially enhanced for LIVE use into a
typical guitar amplifier.
Named after Jerry Donahue of the Hellecasters, these pedals are truly pro
sounding machines. 110% class in a small package!
The distortion character has grunt and is fizz free just like a low powered
class A or AB1 boutique combo. The blues tone? Think Eric Clapton 'Me
And Mr Johnson' or 'From The Cradle'!! But it's no slouch either. In high
gain modes it can provide that classy big 4x12" tone too!
Just plug JD10 into the input of your guitar amp, like any ordinary stomp
box. It works just like a high class preamp from many upmarket amps. All
the controls operate exceptionally smoothly and have greater that average
range, from jangly cut to full throated bass drive.
The footswitchable TruTone bypass circuit prevents tone losses when in by
pass mode. It will even drive a cable up to 100 metres long without tone
loss! It stops those cheap chorus, flanger and delay pedal from squashing
your guitars tone when they are ALL set in their bypass mode. Thanks
TruTone!
These fab pedals are British Made and have many never seen before
features. The ‘two-tone’ black cases are made from special ‘sand’ grain
and black powder coated 16swg steel, making them exceptionally rugged
and able to withstand the hard life they might get on the road.
AC Adaptor Operation - JD10 runs on a regulated adaptor giving a
POSITIVE or NEGATIVE output of 9 DC. JD10 is equipped with circuitry
that senses the incoming voltages and AUTOMATICALLY adjusts itself
internally to the correct polarity. NO HARM CAN BE DONE BY USE OF
INCORRECT AC ADAPTORS, providing the above guidelines are adhered to.
Battery Operation - JD10 will run on a 9 volt Alkaline battery when an
AC adaptor is not convenient. Remove the four outside screws holding the
base to the top. The battery connectors will be found inside.

Setting The EQ Controls To Match By-Pass Tone
It is not possible to set the EQ controls for a perfectly flat tone response. So below, we have given you a setting
which most closely matches the tone of the BY-PASS signal when the pedal is set up for a clean tone in the ACTIVE
setting. However, it is normal for the tone to appear to lose treble as distortion is progressively introduced. This is
true of ANY distortion pedal or amplifier and is due to high frequency harmonics in the signal being lost in the
distortion process. However, you can adjust the EQ controls to compensate for this.
The setting above is only a guide to start from, so do experiment with tones. But remember the golden rule...
There are NO correct settings - if it sounds good to you, then that’s all that matters. However, the settings will vary
wildly from one instrument to another, due to the many types of pickups around these days. So we can’t sensibly
be asked to give you that much guidance as to settings for particular sounds.
Choosing An AC Adaptor For Best performance
This latest version of JD10 requires that it is run from a REGULATED AC Adaptor with a current rating
of 100mA or higher, or a 9 volt battery.
You should use a REGULATED 9 volt adaptor giving a POSITIVE or NEGATIVE output voltage. The built in
AUTOSENSE™ circuitry ensures that no harm can be done to JD10. Higher voltages up to 16 volts can be safely
used too. Although JD10 will still continue to work well, it will lose its unique ‘flat-topped’ style of valve-like
distortion sound, so a 9 volt regulated adapter is strongly recommended.
Why? JD10 MK2.3 has new distortion circuitry which relies partially on power supply ‘limiting’ to create its unique
distortion sounds. This is just how a valve creates its distortion too, so you can imagine this is an important step in
the function of the unit.
What is a ‘regulated’ power supply? REGULATED means that the output voltage of the AC Adaptor is held at a
constant 9 volts regardless of the current being drawn from it by the pedal. A REGULATED supply not only ensures
the best distortion sounds (in the case of JD10 2.2 onward), but also removes the chance of any 100/120 Hz hum
from being heard in with the output signal going to your amplifier.
At First Switching On JD10
It will take about forty seconds for JD10 to settle down after first powering up. This is because the biasing of the
circuitry needs to ‘charge up’ and some small pops could be heard when you operate the footswitch. This will soon
disappear, but then JD10 2.3 has unique electronic circuitry unlike any other pedal... as you will hear for yourself.
Anyway, you wouldn’t worry if it was a valve amp would you?
