The back panel contains all the rest of the main connectors (sockets):
Special notes:
•
The HLS (hearing loss simulator) connector is currently not used. Use the Standard Headphone
and HF Headphone connectors for HLS. This is prepared for future use.
•
In addition to the standard DD45 headset, four other air conduction transducers may be used
(they all connect to specific outputs on the AC40):
•
HDA300: High Frequency requires a HF headset.
•
CIR33 for insert masking: Insert phone CIR33 for insert masking has a limited sound
quality, making it only adequate for masking noise presentation.
•
EAR-Tone 3A or 5A general purpose insert phone: Insert headphone EAR-Tone 3A or
5A are high quality transducers that may be used instead of the DD45/TDH39. It
improves cross hearing from the normal approximately 40dB of the TDH39 to
approximately 70dB. Masking as well as avoiding over-masking is thus easier with this
type of headphone.
•
IP30 insert phone is the standard insert phone with same properties as EAR-Tone 3A
•
Currently FF3/FF4 (both the powered and non-powered) is not used. This is prepared for future
use.

assistant wearing a headset connected to the "Assistant Monitor" output.

The LAN connection is currently not used for any application (only internally in production).
