Take the LV1 tube and inspect the pins noting the large space

between two of the pins. This space will align with the same larg-
er space between two of the pin holes on the socket. Insert the
LV1 tube into the LV1 tube socket, making sure all pins and pin
holes are aligned (see Figure 10). Do not force the tube into the
socket. Rock the tube gently while pushing slowly until the tube is
firmly seated. Repeat this step for the remaining tubes, LV2 tube to
the LV2 tube socket etc. V1 tube to the V1 tube socket, V2 tube to
the V2 tube socket etc.

Once all the tubes are installed, no other adjustments or instal-

lation of any other parts is necessary. Replace the Top Cover,
and using the Phillips screw driver, fill all the screw positions with
the screws provided. There are extra screws provided in case you
misplace a few.

N o t e : Partially install the screws, then go back and tighten them all. Do not over-tighten.

You have now completed the preliminary steps of setup before

your listening pleasure will begin.

LINE SERIES

PRE AMP LIFIER  AND P OWE R

SUP PLY CH ASSIS P LACEMENT

Under no circumstances should the Line 2 or Line 3 Power Supply
be placed directly on top of the Preamplifier, or the Preamplifier
placed on top of the Power Supply. This will not allow adequate
ventilation, and overheating will result. The feet of the 

LINE Series

preamplifiers are temperature sensitive and may deform if
exposed to excessive heat.

The units must be placed on a hard flat surface (

N O T

on carpet),

preferably side by side or on separate shelves with plenty of
unobstructed space all around the preamp to allow for free move-
ment of air for proper cooling. Do not operate these preamplifiers
in an enclosed cabinet - overheating will result.

Allow 

at least

6” (15 cm) of clear space all around the

Preamplifier chassis for proper ventilation.

CONNECTING EXTERNAL EQUIPMENT

If you have XLR Balanced connections available on your source
units a connection made with these inputs will yield optimum sonic
performance. Connect the left channel output of the source unit to
the left channel input of the 

LINE Series

preamplifier, and the right

channel output to the right input.
Note: The XLR configurations are as follows:

Pin#1- Ground
Pin#2- Positive
Pin#3- Negative
Connector Body - Chassis ground

If the balanced outputs are not applicable for use, the RCA 
single-ended (unbalanced) outputs should be used when 
connecting the source unit to the RCA single-ended inputs on the

LINE Series

preamplifier, left channel to left, right channel to right.

There are also two optional connections that can be made for
Custom Home Theatre Installations. These are the I.R. Jack and the
Relay Trigger. They are discussed in more detail on page 8.

Figure 10 

- Tube pin alignment with the socket.

Note the larger space 
between two of the pins and
holes for proper alignment 
of tube and socket.
