All multi-party calls are narrowband
calls. When you press the CONF button
to add another party, any wideband
connection you may have had with your
first party will revert to narrowband,
and you will no longer see
on your screen.
Your connection will also revert to
narrowband if another party picks up
a phone which is connected in parallel
with your SoundStation VTX 1000.
Excessive noise on the line will also
cause the phone to automatically switch
to narrowband. If this problem persists,
contact your pone line telephone service
provider or system administrator. VTX
1000 is designed to provide wideband
service on business quality phone lines.
Reverting to Narrowband
If a remote party cannot hear you at all,
cannot hear you well, or cannot hear
you via particular microphones, first
determine whether any external audio
input devices are in use, such as a
wireless microphone or mic mixer.
If such devices are in use, check
that all the connections are secure.
(See “Connection Diagram,” pg. 31.)
Then, access the Audio Setup (as
described on pg. 17) and make sure that
Aux Input (pg. 19) is On, so that input
from these devices is recognized.
If such devices are not in use,
access the Audio Setup (as described
on pg. 17) and make sure that Console
Mics (pg. 20) are On.
If the only such devices in use are the
VTX’s Extended Microphones, access
the Audio Setup (as described on pg.
17) and make sure that Console Mics
(pg. 20) are On. This setting controls
both the internal microphones and the
Extended Microphones.
Remote Party Cannot Hear You
If physical damage is severe enough
that the internal parts become visible,
disconnect the SoundStation VTX 1000
immediately. Do not reconnect it to
the telephone network until the
SoundStation VTX 1000 has been
repaired.
Physical Damage
Do not move the SoundStation VTX
1000 console while it is in use.
Keep your hands away from the unit
during calls.
Keep papers, cups, coffee pots, etc.,
away from the unit.
At the beginning of a call, let someone
at each location speak in turn for a few
moments, to enable SoundStation VTX
1000 to adapt to its environment.
The other party may be using lower-
quality equipment or a half-duplex
conference bridge, in which case there
may be little you can do.
Try calling again to see if another line
provides a better connection.
Short Silences, Echoes, or Clipped Speech
If sound quality is problematic, or there
is no sound, first determine whether any
external audio output devices are in use,
such as a subwoofer, PA system, or tape
recorder.
If such devices are in use, check
that all the connections are secure.
(See “Connection Diagram,” pg. 31.)
Then, access the Audio Setup (as
described on pg. 17) and make sure
that Aux Output (pg. 19) is set
correctly. If a Subwoofer is in use,
set Aux Output to Subwoofer.
If any other device is in use,
set Aux Output to Ext Speaker,
Record Out, or Off.
Problematic Sound Quality or No Sound
Noisy equipment, such as a computer or
fan, may make it difficult for you to hear
the other party. Both parties should turn
off any noisy equipment.
Try calling again to see if another line
provides a better connection.
