Configuring the Forum IPhone PC
Audio Tab
Select the sound card for the audio input and output. The selec-
tion is necessary if multiple sound cards or sound-card drivers are
installed. The settings for input and output must refer to the same
device. When using DirectSound too, the same device must be
selected for input and for output in the system’s sound and multi-
media settings.
You can also specify which connected device emits the ringing
tones, e.g. a connected headset or a speaker connected to the
sound card.
The Echo cancellation option reduces audible echo for callers.
An echo will be heard if a speaker and a microphone or a badly
suppressed headset is used. If this option is activated, the micro-
phone is suppressed, or for hands-free calls it is muted during
calls via the receiver as soon as the caller speaks.
The Local echo option is only available if your sound card sup-
ports the direct output of microphone data to the speaker. This
means that speech is played back without delay in suppressed
form on your speaker, in the same way that it is on your tele-
phone. This option is only recommended if you are using a head-
set.
The Use DirectSound option allows multiple applications to out-
put acoustic signals simultaneously. This means that you can use
the Forum IPhone PC while playing music data, for example.
Deactivate this option if you experience problems with the input
and output of audio data.
