Record Monitor; Sampling Rate - Toshiba T2150CD Series Manual

This feedback occurs repeatedly and causes a very loud, high-pitched noise. It is a common
phenomenon that occurs in any sound system when the microphone input is output to the
speaker (throughput) and the speaker volume is too loud or too close to the microphone.
You can control throughput by adjusting the volume of your speaker or through the Record
Monitor or Mute functions.

Record Monitor

This check box feature in the Recording Control Utility controls throughput from the
microphone to the speaker during recording. When the sound system software is installed for
the first time, this feature's default setting is off (no throughput). Turning it on may cause
feedback during recording sessions. If this occurs, either turn down the speaker volume or
turn off the Record Monitor option.
Mute
This button under the Mic control in the Mixer Utility controls the throughput from the
microphone to the speaker during all functions except recording. When the sound system
software is installed for the first time, this feature's default setting is enabled (no throughput).
Disabling the Mute feature may cause feedback during normal operation of the computer. If
this occurs, either turn down your speaker volume or enable the Mute feature.

Sampling Rate

The option for 44.1 kHz sampling rate in the Extended Recorder Program has been removed
due to the large system requirements needed to record at this sampling rate. Recordings made
at this sampling rate could be distorted. For distortion free recording please use the 22.05
kHz sampling rate.
Numeric Keypad and Arrow Key Overlay
You can use part of your keyboard as a ten-key keypad in either numeric mode (for numeric
data entry) or arrow mode (for cursor and page control). The keypad overlay is indicated by
white markings designating numbers and arithmetic functions for numeric entry or arrows and
page indicators for cursor and page control.
