PRE35 Prisma Preamplifier User Guide 19
These instructions help you get the best possible sound
from your PRE35.
Phase
The phase of the AC supply can make a significant
difference to the sound.
Use the Polarity Pen supplied with the PRE35 to verify
which pin is live on your AC power cable.
Ensure that the live pin of the AC power cable is
connected to the left-hand pin of the power connector,
viewed from the back panel:
Live
Burn-in
Your Primare will start to sound best after an initial burn-in
of approximately 24 hours.
You will notice a further smaller improvement in sound
quality for at least another 3 days’ playing.
RS232 and trigger
The RS232 input allows you to connect the PRE35 to a
controller system. Use a twisted (null modem) cable. For
more information contact Primare at [e-mail] or
visit www.primare.net.
The Trigger output allows the PRE35 to switch on other
devices, such as a DD35.
Using the PRE35 with a DD35
Your PRE35 is an ideal companion to the Primare DD35
CD Transport. For best results link the two products
together as follows using the two cables supplied with the
PRE35:
To connect the trigger cable
The Trigger cable ensures that the DD35 switches on, or
to standby, when you operate the O button on the front
panel of the PRE35.
Connect the Trigger cable from the PRE35 TRIG OUT to
the DD35 TRIG IN.
