INTRODUCTION
THANK YOU!...
for choosing the Manley Laboratories Masteringroom-Standard Reference Preamplifier. Designed
around the concept that less is more, the Masteringroom-Standard preamplifier uses the best
available parts with the shortest, cleanest, signal path possible. With the use of our own C.N.C.
milling machine, we can provide you with a superb sounding machine with elegant packaging.
Please take a few moments to read through this manual, there may be features and information about
this preamplifier that you do not know, and it is in your, and our here at Manley Labs, best interest
that you do.
Thank you again, and please enjoy!
GENERAL NOTES
LOCATION & VENTILATION
The Masteringroom-Standard preamplifier must be installed in a stable location with ample
ventilation. It is recommended, if this unit is rack mounted, that you allow enough clearance on the
top and bottom of the preamp such that a constant flow of air can flow through the ventilation vents.
We also recommend that the preamplifier be placed at least 10 inches away from its amplifier.
WATER & MOISTURE
As with any electrical equipment, this preamplifier should not be used near water or moisture. If
liquid enters the preamplifier, it must be immediately returned to your deal for servicing.
SERVICING
The user should not attempt to service the preamplifier beyond that described in the owner's manual.
Refer all servicing other than tube replacement to Manley Laboratories.
SPECIAL NOTES
Tubes may become loose during transit. Straighten and press down each tube before plugging the
preamplifier into the mains socket. Furthermore, NEVER touch the tubes after the preamplifier has
been switched on, the tubes become very hot during operation and should only be handled after the
power has been turned off and the tubes have cooled.
WARNING!

MAINS CONNECTIONS
Your preamplifier has been factory set to the correct mains voltage for your country. The voltage
setting is marked on the serial badge, located on the rear panel. Check that this complies with your
local supply.
Export units for certain markets have a moulded mains plug fitted to comply with local requirements.
If your unit does not have a plug fitted the coloured wires should be connected to the appropriate plug
terminals in accordance with the following code.
GREEN/YELLOW EARTH terminal
BLUE NEUTRAL terminal
BROWN LIVE terminal
As the colours of the wires in the mains lead may not correspond with the coloured marking identifying
the terminals in your plug proceed as follows;
The wire which is coloured GREEN/YELLOW must be connected to the terminal in the plug which is
marked by the letter E or by the safety earth symbol or coloured GREEN or GREEN and YELLOW.
The wire which is coloured BLUE must be connected to the terminal in the plug which is marked by
the letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal in the plug which is marked by
the letter L or coloured RED.
DO NOT CONNECT/SWITCH ON THE MAINS SUPPLY UNTIL ALL OTHER CONNECĀTIONS HAVE BEEN MADE.
