SETTING UP THE T35 - DETAILED INSTRUCTIONS

SELECT A LOCATION

The transmitter is usually located near the sound system amplifier or mixer for easy access to an audio

output signal. Position the transmitter on a level surface. It should be free from metallic objects that

might interfere with the antenna signal.

For permanent installation, the PPA T35 transmitter can be rack mounted. Use the Williams Sound RPK

005 or RPK 006 rack mount kits. Make sure there is good electrical contact between the transmitter chas-

sis and the rack cabinet.

INSTALL THE ANT 025 WHIP ANTENNA

NOTE: If the T35 is going to be rack mounted, you will not be able to install the ANT 025 whip antenna.

For rack mounting, consider installing a remote antenna (see following section).

The PPA T35 is shipped standard with a single ANT 025 whip antenna. The ANT 025 threads on to a stud

recessed in a hole on the top of the transmitter. Screw the antenna clockwise until the connection is

secure (Figure 4). Do not use excessive force to tighten the antenna. For maximum performance, extend

the ANT 025 antenna to its max. height of 39”. For operating the T35 in remote locations, a coaxial

antenna (ANT 005) or Wall Mount Dipole antenna (ANT 024) can be installed. The external antenna jack

is located at the rear of the T35 transmitter (Figure 4). The external antenna impedance is 75 ohms.

REMOTE ANTENNA TIPS:

Position the ANT 005 or ANT 024 antenna so the elements are vertical. The last 80 inches of the ANT

005 contain the elements. DO

NOT

install the antenna elements horizontally

The antenna should be

placed as close to the listening area as possible (10 to 15 feet above the floor). DO

NOT

install the

antenna directly above the listening area. There is a null in the coverage area off the ends of the anten-

na. DO NOT install the antenna around any significant amount of metal material; this may deflect and

absorb the radio signal.

The ANT 005 and ANT 024 cables are classified as Class II wiring and may be installed in conduit

with other Class II wiring. The antenna SHOULD NOT be installed with Class I (power) wiring. DO

NOT connect the coaxial cable to the building or electrical ground in any way.

Included:

ANT 025 Whip Antenna

Optional:

Coaxial Antenna (ANT 005) or

Wall Mount Dipole (ANT 024)
