GENERAL NOTES LOCATION & VENTILATION The Purist 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 slots.
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 com- plies with your local supply. Export units for certain markets have a moulded mains plug fitted to comply with local require- ments.
CONNECTING YOUR PREAMPLIFIER Setting up your preamplifier is rather easy. 1. Please refer to page 7 diagram 2 for an illustration of the back of the preamplifier. 2. There are three sets of main outputs, two identical sets of UNBALANCED RCA and the other BALANCED XLR.
VOLUME SELECT SET GAIN OPERATE HIGH TAPE MANLEY TUNER VIDEO MUTE VARIABLE FEEDBACK SET GAIN Switch to select general gain of the preamp to personal preferences. Due to a lack of current standards of power amp and preamp sensitivity this feature provides a simple method to scale the overall gain of the system or allow one to reduce the power amp gain to reduce noise.
REAR PANEL C D E F G H I J K FUSE HOLDER Replace with 1A SLO-BLO fuse only. IEC MAINS SOCKET Standard IEC mains socket (120/240 VAC as indicated) OUTPUT (XLR) Left (upper) and Right (lower) output XLR's. BALANCED OUTPUT (RCA) Separate output to the Left and Right XLR outputs.
OPERATIONAL NOTES SWITCHING ON The power switch is located on the right hand corner of the front panel. Flip the switch up to turn on the preamplifier and down to turn off the preamplifier. RUNNING It is not recommended that you leave your preamplifier permanently switched on. This only wastes electricity and tube life.
