INSTALLATION

1)

Provide adequate ventilation.

2)

Do not operate on carpet or any other surface that might block air flow.

3)

The chassis will become warm in normal use.

4)

Do not allow the chassis to touch any metal parts, such as the frame of an equipment
rack. This might create a parallel ground path that could degrade the sound of your
system.

5)

Input connection is via single ended RCA jacks or XLR jacks (which can be from
balanced or unbalanced sources). Output can be on RCA or XLR jacks, and can be
set for balanced or unbalanced loads, with or without ground connection at the
preamplifier.  IMPORTANT:  READ  THE  SECTION  ON  “OUTPUTS  &  GROUNDING
SWITCH”. Connect line level inputs (CD, Tuner, Tape, etc.) to the appropriate RCA
input jacks on the rear panel. Note: with the exception of Phono (when fitted), all
inputs are “line level”

6)

Connect phono cables to the rear panel MM or MC inputs labeled “Phono.” Connect
the  ground  wire  from  the  turntable  or  phono  cable  to  the  “Ground”  terminal
provided on the rear panel. Set the MM / MC switch to reflect the input jacks being
used.

7)

Connect the power cables from the power supply to the preamplifier. Note that
each has a locating key and a locking collar. Be sure to insert the connector properly,
and fully tighten the locking collar.

8)

Connect the input and output cables.

9)

Connect  the  power  supply  to  the  correct  voltage  source.  The  voltage  may  be
selected by means of the removable selector card located underneath the fuse in
the power connector. Remove the cards and reinstall so that the desired voltage
may be read. Avoid power conditioners that float the ground pin. ALWAYS connect
power cord to component before plugging it into an AC outlet, and make sure that
unit’s power switch is set to the “off” position before making the final connection.
For best performance, try to route the power cord away from signal cables. 

10)

Pay close attention to power quality, and be aware that different power cords can
alter the sound. The backlit meters show variation in power line voltage as reflected
to the audio circuitry.

11)

Set the logo illumination switch to bright, dim, or off.
