CP-4T
TOOLS NEEDED FOR CP-4T WALL-MOUNT INSTALLATION:
a) Level
b) One pencil
c) 1 Philips #2 screwdriver OR One Power Drill with A LOW TORQUE SETTING and a Philips #2
screwdriver bit
d) Four #10 or #12, 2.5-3” (4-5cm) Pan head Screws (Two for each speaker bracket) for mounting
into wall stud OR Four minimum 10 lb. (5kg) Wall Anchors if stud-mounting is unavailable
TIPS ON DESIGNING/INSTALLING A 70/100 VOLT AUDIO DISTRIBUTION SYSTEM WITH KLIPSCH CP-4T SPEAKERS:
Using a quality SPL meter, first determine the ambient noise level of the business you are designing a system for. Then determine the area(s) the customer wants to cover and
if they desire a Background or Foreground music system for their particular business.
Ambient Noise Levels: Measure at peak business hours to determine highest level
Background Music Levels: Usually 3-6 decibels (dB’s) above the ambient noise level in an area
Foreground Music levels: 10+ dB’s above the ambient noise level (used in high-energy environments)
When determining speaker heights to mount over a given area, note the Inverse Square Law for sound and the fact that when placing a speaker in a corner 3 dB additional
output (+3dB) is obtained. In an area people are seated calculate coverage to 3.5 ft. (1m) from floor, in an area people stand 5 ft. (1.5m) from floor
Space speakers on wall all at the same height aimed down toward
listening area. Space according to coverage pattern (90°). Stagger
opposing speakers if within 30 ft. (9m) on opposite wall. Closer
spacing produces most even coverage. Avoid obstacles in front of
speakers For more reverberant rooms mount speakers lower at
8-12 ft. (2.4-3.7m) from floor.

Parallel Wiring
70/100 Volt
Line Distribution Amp
Choose a 70/100 Volt Line Distribution Amplifier based on
total wattage needed to power amount of speakers PLUS, we
recommend, 50% additional power to cover additional dynamic
headroom/future expansion. Wire all speakers in parallel.
Example: Eight CP-4T speakers tapped at 5 watts each =
8 x 5 = 40 watts + additional 50% wattage = 60 watt amplifier
