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. VOICE: Choose one of four levels for
VOICE. You will see the following displays
when you choose VOICE level one, two,
three or four:

Each setting of FREQUENCY
COMPENSATION increases the audio program

at 4500 Hz.
BASS REDUCTION: Choose one of three levels for BASS REDUCTION using the three
buttons. You will see the following displays:

Each increased setting of BASS REDUCTION removes more audio content below 500 Hz.

COMPRESSION restricts variation in audio
program output level.
ALL CATEGORIES: A category that was not adjusted will show a zero when the settings

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.
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.
How to adjust the AV205
You need the Audiology Remote to
adjust the AV205.
Make sure the AV205 is connected to AC
power. To turn on the AV205, you can press
the POWER button on the AV205 endcap,
press the POWER button on the standard
AV205 remote, or press either VOLUME
button on the Audiology Remote.
Adjustments:
FOCUS: Choose one of three levels for FOCUS using the three buttons. You will see the
following when you choose FOCUS level one, two or three:
, ,
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.
Each setting adds synthetic harmonic
content to formants in the audio program.
This can increase dialog intelligibility for
a client.
