Enclosed Two–Way In–Wall Speaker Pairs
Easy to install in–wall speakers are ideal for background music, paging, home theater or any
general music application. Their wide frequency response and above average power capacity
make them ideal as main, surround or background speakers. System consists of a woven
fiberglass, blue cone woofer, with rubber surround, and a 1" titanium swivel dome tweeter.
The addition of a molded PVC back–box ensures uniform sound quality regardless of
mounting location, while protecting the speaker from insulation debris and temperature
extremes. Rotating mounting clips allow fast installation in to drywall with no additional
hardware. All will mount in a standard 2 x 4 studded wall. Each speaker is 8ohm. Sold in pairs.

Multi Room Speaker Distribution Strip
Essential for distributed residential sound installations,
this terminal strip provides a convenient method of
connecting numerous pairs of speakers to a single pair of
binding posts. Input terminals are heavy-duty, gold plated
brass, five-way binding posts, which will accept single
or paired banana plugs or bare wire up to 8AWG. Each
output connection features detachable screw terminal
strips which accept up to 14AWG wire. Internal PC board
circuit is reinforced with internal point–to–point 14AWG
wiring, for improved current capacity. Compact size
allows easy location behind equipment. Screw holes
allow easy wall mounting and rubber feet are included
for shelf top use. Note: Terminal strip is straight parallel
connection and provides no impedance protection. It is
intended for use with 70V distributed speakers, or 8ohm
systems that utilize impedance matching volume controls.
Specifications: •Power capacity: 200W RMS per channel
•Dimensions: 2" (H) x 2.25" (W) x 10.5" (L), including
binding posts.

Multi Room Speaker Distribution Strip
Designed for use in multi room sound distribution
installations where individual speaker selection is
not required. Impedance protection circuit allows up
to eight sets of 8ohm speakers to be connected to a
stereo amplifier, and appear as a 4ohm load. Completely
independent left and right circuits allow compatibility
with all amplifier types. Attached mounting plate allows
installation into standard 19" racks, or between studs
spaced on 16" centers. Features: •Color coded push
terminals accept up to 8AWG wire •Switchable impedance
protection •Non-inductive resistors for full frequency
response •Rugged aluminum housing with black finish
Specifications: •Power capacity: 120W program per
channel •Frequency response: 20Hz~20KHz

Speaker Selectors
✔Volume adjustment in each zone
✔A/B source selection
✔100W RMS capacity
Versatile speaker switches allows connection of up
two six pairs of speakers, to two different stereo sources,
with individual volume control of each pair. Volume
adjustment and impedance matching is accomplished
through internal heavy-duty multi-trapped transformers.
Rear screw terminal strips accept up to 14AWG wire,
and are removable, allowing easy connection of multiple
cables. Power capacity: 18W/50W RMS/program per
speaker, 100W/150W RMS/program total. Dimensions:

Speaker Selector/
Distribution Panel
Impedance matching speaker selector/
distribution network is ideal in situations where up to ten pairs of speakers are to be connected to a single amplifier,
and individual on/off selection is required. Additionally, a two–position source selector allows global selection from
two different source systems. High–powered non–inductive resistors ensure that the speaker load never falls below
4ohm, even when all ten pairs of speakers are operating. Heavy–duty rocker switches are rugged enough for commercial
use, while remaining suitable for residential applications. Detachable terminal strips accept up to 14AWG wire.
The
rugged steel panel is intended for 19" rack mounting, and occupies two rack spaces. Power capacity: 200W per channel.
Overall dimensions: 3.5" (H) x 19" (W) x 2" (D). Limited quantities.
