Manley STEREO VARIABLE MU LIMITER / COMPRESSOR - 1994 - 3/2004 - Manual (Page 4)

MAINS CONNECTIONS
Your unit 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
CONNECTIONS HAVE BEEN MADE.

TROUBLESHOOTING NOTE: Occasionally we have had units sent to us to service that had no problem. The
symtom was clipping only when the unit was in the processing chain. Remove the unit and distortion
gone. However in the shop - no problem. The cause was a combination of the somewhat low input
impedance of the Limiter/Compressor and the somewhat "wimpy" line driver of the preceding device.
The solution - change the order of processing so that a more professional device fed the Limiter /
Compressor. The input impedance is over 1.2 Kohm and most devices are supposed to drive 600 ohms
(which is twice as hard) but in this era of ICs and semi-pro gear claiming to be pro well.......
