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.
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.
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 two sets of main outputs, one set RCA and the other XLR. The pin out for the XLR is as follows: PIN1 - ground, PIN2 - common/ground (-), PIN3 - hot (+). Connect either the XLR or RCA output to the input of your amplifier. 3.
FRONT PANEL A SELECTOR SWITCH Switch to select between inputs. Counterclockwise: Phono (MM or MC), AUX (auxilary), DIG (CD), TAPE, TUNER, VIDEO. NOTE: always turn volume control (level) down before switching selector switch. B LEVEL CONTROL Adjust the stereo gain of the selected signal. Both channels are always amplified by the same amount. C FULL / REDUCED SWITCH Provides a course volume adjustment of 5 dB. The level control will have better resolution when set to reduced, but less gain.
REAR PANEL A IEC MAINS SOCKET Standard IEC mains socket (120/240 VAC) B FUSE HOLDERS Right & Left channel fuses. Replace with 1A SLO-BLO fuse only. C VOLTAGE SELECTOR SWITCH Selectable to 110,120 / 220,240 VAC. Set to the proper voltage you are using. D OUTPUT (XLR) Left (upper) and Right (lower) output XLR's. Standardly shipped PIN3 hot. E OUTPUT (RCA) Paralled output to the Left and Right XLR outputs. F RECORD OUTPUT Buffered record output stage. Set at input line stage level.
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. Your preamplifier has solid state rectification and reaches peak operating condition in approximately 30 minutes. TUBE LIFE As with all tubes, their quality degrades with age.
