Audiologist Guide
for Adjusting ZVOX Audio AV205
The AccuVoice AV205 is a compact amplified 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 configured for the client’s specific
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
ACCU-
VOICE
button selects AC
_
1 and AC
_
2 and then the normal surround mode (desig-
nated by Sd). The programmed AccuVoice mode (AC
_
1) is created by the Audiolo-
gist. 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.

AUDIOLOGY
The AV205 has five separate adjustment categories that apply to AC
_
1 mode:
FOCUS
provides three levels of increasing emphasis on dialog, with a correspond-
ing reduction of music, sound effects and other background sounds.
VOICE
adds an adjustable amount of synthetic harmonic content to dialog
(specifically 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 ele-
ments 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 five parameters are set by the Audiologist, he or she can review the five
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.
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 adds synthetic harmonic content to formants in the audio program.
This can increase dialog intelligibility for a client.
FREQUENCY COMPENSATION:
Choose one of three levels for FREQUENCY
COMPENSATION. You will see the following displays:
,
,
Each setting of FREQUENCY COMPENSATION increases the audio program content
centered 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:
Choose one of three levels for COMPRESSION using the three
buttons. You will see the following displays:
,
,
COMPRESSION restricts variation in audio program output level.
ALL CATEGORIES:
A category that was not adjusted will show a zero when the
settings are reviewed—

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.
