Audiologist Guide For Adjusting The ZVOX Audio AV205
The AccuVoice AV205 is a compact
amplied speaker system created by
ZVOX Audio for the audiology profession.
With the AV205, an Audiologist can
provide a client with a compact TV
sound system congured for the client’s
specic audio needs.
The AV205 features the ability to switch
between three sound modes using the
ACCUVOICE button on the client’s
remote control. Repeated presses of the
ACCUVOICE button selects AC_1 and
AC_2 and then the normal surround mode
(designated by Sd). The programmed
AccuVoice mode (AC_1) is created by the
Audiologist. Standard AccuVoice mode
(AC_2) helps people with minor age-related
hearing loss. The SURROUND button sets
which of three multi-channel sound modes
is used (Sd_1, Sd_2 and Sd_3). Refer to
the User Manual of the AV205 for further
information about the controls available
on the standard AV205 remote control.
The Audiologist uses the ZVOX Audio
Audiology Remote to make the adjustments
described below. This remote control is
available separately for the Audiology
profession and should be retained by
the Audiologist. Each AV205 comes with
standard remote control, which provides
volume, mute and tone adjustments plus
selection of the digital or analog input.
A diagram of each remote follows.

Increasing the FOCUS setting reduces parts of the multi-channel audio program that are not
monaural. The vast majority of dialog on multi-channel TV, video and movie programming is
monaural, so this selectively removes distracting program material.

The AV205 has ve separate adjustment categories that apply to AC_1 mode:
FOCUS provides three levels of increasing
emphasis on dialog, with a corresponding
reduction of music, sound effects and other
background sounds.
VOICE adds an adjustable amount of
synthetic harmonic content to dialog
(specically to “formants”) to better suit
the remaining hearing capability of a client.
There are four increasing levels.
FREQUENCY COMPENSATION provides
three increasing amounts of emphasis
centered on 4500 Hz. Both amplitude
and bandwidth increase with
higher settings.
BASS REDUCTION reduces output below
500 Hz. This eliminates distracting elements
of wide-range sound that can
interfere with dialog intelligibility.
LEV ELI NG
COMPRESSION provides four levels of
restricted volume variation. It increasingly
forces all program material to be played
at the single output level set by the
volume control.
Once the ve parameters are set by the
Audiologist, he or she can review the ve
settings by repeated presses of the
REVIEW button. The CLEAR button
returns all settings to the defaults.
