Selecting Power Levels
The front-mounted selector switch is used to
set the appropriate power level or impedance
for your system. Using a small, flat-blade screw-
driver, turn the knob until the slot points to the
power level you require.

00V SYSTEMS
Both power setting scales for 70V and
1
00V sys-
tems are labeled on the speakers. On the
1
00V
scale, the last position clockwise is marked with
a symbol. Do not use this position in
1
00V
systems.

SYSTEMS
The fully counterclockwise position of the setting switch is the
1
6-ohm position.This
setting is suitable for use with low-impedance amplifiers that tyically support 4- or
8-ohm speakers.The speaker’s higher,
1
6-ohm impedance makes it easier to combine
multiple speakers into series - parallel networks while keeping the total system
impedance at a level suitable for low-impedance amplifiers.
25V SYSTEMS
The HFCS
1
will operate on 25V systems, but at
reduced power levels. The chart to the right
shows the conversion from a 70V power setting
to the actual 25V power level.
Accessory
TBCR (TILE BRIDGE SUPPORT RING)
The TBCR is a combination tile bridge and
support ring that assists in securing the
HFCS
1
and in distributing the weight of the
HFCS
1
in various types of installations.
