HT 4V (serv.man2) - JBL Audio User Guide / Operation Manual. Page 3

The HT4H terminal cup has an adjustable foot to angle the speaker toward the listening position.

Loosen thumbscrew.

Slide rod down the desired
amount.

Tighten thumbscrew.

Separate and strip the ends of the
speaker wire as shown. Speakers
and electronics terminals have
corresponding (+) and (–)

terminals. Most manufacturers 
of speakers and electronics,
including JBL, use red to denote
the (+) terminal and black for the
(–) terminal. The (+) lead of the
speaker wire is noted with a
stripe. It is important to connect
both speakers identically: (+) on
the speaker to (+) on the amplifier
and (–) on the speaker to (–) on
the amplifier. Wiring “out of
phase” results in thin sound, weak
bass and a poor stereo image.

With the advent of multichannel
surround-sound systems,
connecting all of the speakers in
your system with the correct
polarity remains equally important
in order to preserve the proper
ambience and directionality of the
program material.

If there is no sound from 
any of the speakers:
• Check that receiver/ amplifier is
on and that a source is playing.
• Review proper operation of your
receiver/amplifier.
• Make sure all wires are
connected. Make sure none of the
speaker wires are frayed, cut or
punctured.

If the system plays at low volumes
but shuts off as volume is
increased:
• Check all wires and connections
between receiver/amplifier and
speakers.
• If more than one pair of main
speakers is being used, check the
minimum impedance requirements
of your receiver/amplifier.

• Make sure all wires are
connected. Make sure none of the
speaker wires are frayed, cut or
punctured.

If there is no sound coming from
one speaker:
• Check the “Balance” control on
your receiver/ amplifier.
• Check all wires and connections

Both the HT4V and HT4H come
with rubber, self-adhesive

footpads, which should be
attached to the bottom corners of

each speaker to protect both your
furniture and the speakers.
