Installation
1166
A surround system must be of the highest quality to realize the full potential of the FAP V1. The entire system cannot have any
weak links in the audio chain, and must be properly installed and adjusted. To hear the true "tube sound" of your FAP V1, the
use of tube electronics including program source and power amplifiers is highly recommended. If your choice is solid-state
power amplifiers you can be assured the output impedance is low enough to drive them.
LOCATION
The FAP V1 can produce considerable heat in normal
operation, especially the vacuum tubes, so the primary
consideration when determining a location is to allow for
adequate ventilation. Care must be taken to keep the
ventilation holes in the bottom panel, back panel and top
cover clear. Ensure adjacent equipment does not impede
cool air flow.
Inadequate ventilation can shorten component life,
especially when other equipment raises the ambient air
temperature, so circulating fans should be considered in
tight quarters.
CAUTION! Vacuum tubes get extremely hot
during use. To prevent injury, do
not touch the vacuum tubes while
the unit is operating.
Keep children away!
AC LINE
The FAP V1 operates from a 120 volt, 60Hz AC power
line. Connection is made by a grounded line cord. For
safety considerations only a properly grounded (earthed)
receptacle should be used. Do not break off the ground
pin. The line fuse is accessible from the rear panel. If this
fuse blows, replace it only with the same type and rating
fuse. The correct replacement fuse value is printed on the
rear panel of the unit. If the new fuse blows, this is an
indication of a fault with the unit. Servicing should be
performed only by a qualified technician.
INPUT CONNECTIONS
The input jacks located on the back of the FAP V1 are
RCA style connectors.
OUTPUT CONNECTIONS
The output jacks located on the back of the FAP V1 are
RCA style connectors.
* My reference system is located in a large room 24' wide 34' deep with 10' ceiling height. The room is located in a
basement, and is built with reinforced concrete all the way around including the ceiling. There is a drop ceiling
located 9' from the floor filled with fiberglass above to make a "bass trap". The walls and floor are covered with
thick carpet pad and thick carpeting for room deadening. Each corner has a wall built at the proper angle to
mount the four-corner speaker systems. This provides an eight-sided, octagon shaped listening room that reduces
corner reflections.
The system is tri-amplified with 1 inch soft dome tweeters, two 5" midrange drivers, and eight 10" woofers per
channel, in a flush mounted wall array. The center front speaker is recessed inside the wall and flush mounted.
Side channel and center back speaker locations are also recessed in the walls but I do not use the optional side or
center back speakers at the present time.
I get terrific sidewall images in this room with only five speakers. People who have heard the system think the
side speakers are working and are "shocked" to learn the side speakers are disconnected.
My power amplifiers are 20 watt "all triode" no feedback tube power amplifier driving the tweeters; 40 watt ultra
linear tube power amplifier with 8 dB feedback driving the midrange drivers; and a 250 watt solid state power
amplifier with 20 db feedback driving the woofers. The crossovers are a 6 db per octave passive design placed
between the FAP V1 and the power amplifiers. An equalizer is placed in front of the woofer amplifier to apply
14 dB of bass boost @ 16 HZ to correct for woofer roll off.
Organ pedal notes must be heard and felt to be believed!
