Voices too quiet
Voice Tap supplies a microphone level signal to your powered speakers.
You should get acceptable volume with most computer type speakers, but
some speakers expect a line level (louder) signal. If you need louder
output, try different speakers. Remember, they must be powered, amplified
Voice levels not matched
The relative level of local and far end voices is partially a function
of the telephone. You may want to try a different phone.
No audio output
Make sure you only plug a stereo cord into the stereo output jack. If
you plug a mono plug into the stereo jack, you will temporarily short
out both jacks.
Cannot transmit audio
The three position "Handset Type" switch on the back of
Voice Port selects between (A) electret, (B) dynamic, and (C) carbon telephone
handset microphone types. When you push in the grey "Play" button,
Voice Port replaces the handset with the audio input signal. It is difficult
to determine the type of microphone in a handset by looking at it. Simply
try all three positions for the best match.
Position C is very strong, so you may have to turn down the audio signal
when trying this position. Also make sure the audio signal into the Voice
Port is at line level. You can use a line level or headphone level source.
Phone audio level dropped
The receiver audio level will drop considerably if the audio input
cord is not connected to an audio source. Keep the cord plugged into a
headphone output or amplifier output.
Does not work with headset
Make sure Voice Over is connected between the telephone base and headset
Replacement power supply
Phone Port requires a 18 VDC center positive unregulated power supply
