ports are in order, from top to bottom, J3, J4, J2, J1.
Why, I dunno.
J is marked
"Jumper" and has two empty through holes for a 2 pin
header. It straddles the split between the Digital
Ground Plane (left half) and the Analog Ground Plane
(right half) of the AD1848KP.
J4 Output - speaker
uses a 3.5 mm jack (monaural or stereo)
J1 Sense Input -

The VoiceType Dictation Adapters are uniquely designed
for computational and memory-efficient speech processing
that otherwise would be handled by the main processor in
the PC. With memory for speech processing, the adapters
enable highly accurate, real-time speech recognition to
operate on PCs with 486 processors at speeds as slow as
To support the intense, computational aspects of speech
recognition, the VoiceType Dictation Adapters
incorporate a digital signal processor (DSP). The DSP is
rated at 25 MIPs with a 16-bit wide, external memory
data path, a 16 x 16 multiplier, and a 32-bit arithmetic
logic unit (ALU). Data transfers, multiplication, and
ALU operations are independent and all can be active
during every instruction cycle. In addition to the DSP,
special processing hardware is included on the adapter
to handle arithmetic intensive operations.
The VoiceType Dictation Adapters also include separate
instruction and data memories. The adapters have static
RAM and over 1MB of dynamic RAM directly addressed
VoiceType Microphone Option
The VoiceType Microphone Option with Battery Box (30H2343) provides external power to the microphone and should be used with all sound cards that do not have sufficient power to operate the microphone. Part number 30H2343 should also be used in cases where the user is unsure of the sound card's capability to provide the necessary power.
The battery box for 30H2343 requires two user-supplied
batteries that are not shipped as part of the product.
The expected battery life is 500 plus hours of use.

microphones included with the VoiceType adapters. Andrea
Whitepaper Andrea Active Noise Cancellation (ANC)
Active Noise Cancellation (ANC) is better. It is a dual element microphone system that electronically cancels background noise by creating a signal that is 180 degrees out-of-phase to the noise while amplifying the user’s voice signal. A lower-priced alternative to ANC is NC microphone technology, which is based on passive noise cancellation principles in a single microphone element solution.

seem to fit over my entire head. Is this right?
