® 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.

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.

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.

and analog audio inputs on the AV205 insure it easily connects to virtually
any HDTV. In addition, the AV205 can respond to the client’s preferred
remote control, not just the supplied ZVOX Audio remote.
The AccuVoice AV205 allows audiologists and hearing aid dispensers to fine-tune five different parameters to suit
individual patients’ needs. This guide provides recommended setting based on an individual’s audiogram.
Recommended Settings Based On Audiogram ConfigurationsThe following configurations can be used for various degrees of hearing loss. Use the suggested settings below and vary the volume to compensate for the amount of amplification needed. Press the Clear button to reset to the default settings.

Suggestions for using Compression [CPS]Using this feature ensures the level of sound produced by the device will be restricted (compressed) to fit the dynamic range requirement of a client. Here are examples of the effect of the three settings:
Please note that it is likely that the output level will increase when CPS is activated. The client’s preferred volume level setting will decrease as the CPS level increases.
If the client uses a hearing aid, the following settings are recommend as a starting point for improved intelligibility.
