The audio connectors in your computer are 3.5 mm (1/8-in.) mini-jacks. (For
additional information about the audio and MIDI/Joystick connectors, see
Chapter 8, “Installing external options” on page 87.)
Controlling volume
You can control the volume through several different means:
Ÿ
If you have external powered speakers attached, one speaker has a set
of controls. The power control must be in the On position for the
speakers to operate. You can control the volume by using the volume
control on the speaker. However, this volume control can be overridden
by the software volume control. On some speaker styles, a single
control is used for both power and volume.
Ÿ
The software volume control is accessible through the speaker icon in
the taskbar, which is located at the bottom-right corner of the Windows
desktop.
– If you click the speaker icon one time, the volume control appears.
Use your mouse to drag the volume-control slider up or down to
control the volume, or click the Mute box to turn the audio off.
– If you double-click the speaker icon, a master volume-control
window opens. You can use the settings in the window to control
individually the volume for each type of audio format.
If you are using a Rapid Access II keyboard, you can also adjust the
software volume control through the volume-control button located at the
top-right corner of the keyboard. The software volume control can be
overridden by volume control on the external speakers.
Ÿ
If you have a CD-ROM, CD-RW, or DVD-ROM drive installed, you might
have a volume control and headset connector on the drive. If you
attach a headset to the drive, use the volume control on the drive to
control the volume for the headset. The volume control on the drive has
no affect on the external speakers.
Recording and playing back sound
Procedures for recording and playing back sound vary from program to
program. One method of recording sound is to use the Sound Recorder
program provided with the Windows 98 operating system. Refer to your
operating system documentation for information and instructions.
Note: If you experience interference or speaker feedback while recording,
try reducing the microphone recording volume (gain).
