3 WDRC Channels with 2 adjustable crossover
frequencies and 7 Band Equalizer to optimize fi netuning
of the response for the most unique hearing
loss confi gurations.
Precision Directional Imaging utilizes advanced
directional microphone technology to enhance
speech understanding in noisy environments,
available on the S13 Arista PDI BTE.
Adaptive Feedback Management reduces feedback
at use settings.
Adaptive Noise Management reduces gain of
steady-state noise only in channels where noise is
detected.
MultiChannel Expansion technology reduces
circuit and low-level environmental noise typically
associated with WDRC hearing aids.
In Situ Audiometry and Loudness Verifi cation
administers pure tones through the hearing aid to
establish threshold, UCL, or to verify soft and
loud inputs.
Programmable Indicator Tones for low battery
and MultiMemory.
MultiMemory with up to 3 fully programmable
memories accessed via a push button.
Programmable Telecoil accessed via push button
allows for fully adjustable frequency response of
telecoil within a memory. Enable M/T mode allows
for combined microphone and telecoil inputs.
Wireless FM and Direct Audio Input (DAI) capable
with adjustability of the environmental microphone
below the level of the DAI signal.
Volume Control with optional disable VC feature
within PFS.
M-O Switch.
