MIXERSET UTILITY ================ The MIXERSET utility allows you to adjust the volume and other Mixer controls (such as balance, gain and tone) of the audio output and recording sources supported by your audio card. You can use the utility as a command at the DOS prompt or invoke the MIXERSET interface to control the Mixer settings through a full-screen window consisting of check boxes and sliders. The file provides you detailed information on using MIXERSET. It is organized as follows: * Knowing the MIXERSET Command * Using the MIXERSET Command * Starting the MIXERSET Control Screen * Knowing the MIXERSET Control Screen * Using the Mouse and Keyboard Knowing the MIXERSET Command ---------------------------- The Mixer is configured using the switches that follow the MIXERSET command. To use the MIXERSET command: 1. Change to your sound directory. 2. Type MIXERSET [switches] ... and press . where switches can be one or a combination of any of the following: /? or /H Displays help messages. /Q Runs MIXERSET without displaying the setting information. /P Sets the Mixer according to the PRESET settings in the CTMIX.CFG file. /MA:n;x Sets the MASTER volume and balance of left and right channels. /VO:n;x Sets the VOICE volume and balance of left and right channels. /MI:n;x Sets the MIDI volume and balance of left and right channels. /CD:n;x Sets the CD volume and balance of left and right channels. /LI:n;x Sets the LINE-in volume and balance of left and right channels. /MIC:n Sets the MICrophone volume. /SP:n Sets the PC SPEAKER volume. /TR:n;x Sets the TREBLE level and balance of left and right channels (if available). /BA:n;x Sets the BASS level and balance of left and right channels (if available). NOTE: n specifies the volume level and ranges from 0 to 255, and x specifies the balance of the left and right channels, and ranges from -5 to +5. x must be preceded by ';'. For example, /MA:200;5 sets the master volume at 200 and the balance at 5 (this means that the volume will be reduced in the left channel). /MA:;-5 setting reduces the volume in the right channel. /OPS:ss Sets the audio output switches (OPSW) on or off. ss represents one or a combination of CDz, LIz and MICz, where z is + (on) or - (off). For example, /OPS:CD+ MIC- allows you to receive CD-audio output. It does not allow any sound passed through the microphone to be sent to the speakers. /IPL:ss Turns Left Input switches (IPLSW) on or off. ss represents one or a combination of CDRz, CDLz, MDLz, MDRz, LIRz, LILz, and MICz, where z is + (on) or - (off). /IPR:ss Turns Right Input switches (IPRSW) on or off. Same as /IPL. /IPG:l,r Sets Input Gain (IPGAIN) of left (l) and right (r) channels. Both l and r can be 1, 2 or 4. For example, /IPG:4 sets both left and right channels to 4, /IPG:,4 sets the right channel to 4, and /IPG:4, sets left channel to 4. /OPG:l,r Sets Output Gain (OPGAIN) of left (l) and right (r) channels. Both l and r ranges from 1, 2 or 4. /AGC:+|- Turns Automatic Gain Control (AGC, if available) on (+) or off (-). You do not need to specify the entire string of each switch that you use, as a shortened string entry works equally well. However, at least 2 characters from the beginning of the switch name must be specified with the exception of the following switches: /P, /H, /?, and /Q. For example, MIXERSET /P is the same as MIXERSET /PRESET, and MIXERSET /MA:200;5 is the same as MIXERSET /MASTER:200;5. If you enter multiple MI, IP or OP switches, then priority is given to MIDI (for MI switch), IPGAIN (for IP switch), and OPGAIN (for OP switch). Using the MIXERSET Command -------------------------- The following are some examples on how you can use MIXERSET: * To set the PC speaker volume to 200: 1. Type MIXERSET /SP:200 and press . * To set the master volume to 200 with balanced output through the left and right channels: 1. Type MIXERSET /MA:200 and press . If balance is not specified, both channels will be set equally. * To set all the above in one command: 1. Type MIXERSET /SP:200 /MA:200;0 and press . Starting the MIXERSET Control Screen ------------------------------------ To start the MIXERSET Control Screen: 1. Change to your sound directory. 2. Type MIXERSET and press . The MIXERSET Control Screen appears. Knowing the MIXERSET Control Screen ----------------------------------- The MIXERSET Control Screen consists of the following components: * Volume Slider * Balance Slider * Automatic Gain Control Check Box * Save Button * Input Box * Output Box Volume Slider ------------- Controls the volume levels of the input sources, and the levels of bass and treble. Balance Slider -------------- The sliders control the balance of the left and right speakers for audio sources with stereo capability. Moving the slider to the left decreases the volume of the right speaker but the left speaker volume is left consistent. The opposite applies when you move the slider to the right. Automatic Gain Control Check Box -------------------------------- The Automatic Gain Control (AGC) check box (if available) automatically adjusts input gain from the microphone to a level suitable for recording. Save Button ----------- The Save button saves all changes made to the Mixer to the CTMIX.CFG file. The new setting will be used the next time you preset the mixer setting with the command MIXERSET /P. Input Box --------- The Input Box enables you to select the audio sources you want to control as input to the Mixer. The audio sources available are MIDI, Line and Microphone input, and CD-audio. You can direct these audio sources through the left or/and right input channels of your Mixer. NOTE: To get a stereo sound effect, make sure that the left channel signal of the audio source is directed to the Left-In channel and the right signal to the Right-In channel. The Spin buttons increase or decrease the input gain. NOTE: The gain increases or decreases the amplification of an audio source. Output Box ---------- The Output Box enables you to select the audio sources you want to control as output from the microphone, Line-ln, and CD-Audio to the left and right speakers. You can select one or a combination of the above audio sources playing through the card. Using the Mouse and Keyboard ---------------------------- Using the MIXERSET interface, the Mixer can be configured with a mouse or a keyboard. For mouse control: * Choose the option if it is a check box. * Move the slider by the click and drag method or click at the extreme end of the slide to increase or decrease the Volume, Tone and Gain. * To quit MIXERSET, choose the Control-menu box. For keyboard control: * Press to move from one group to another. * Press to move backwards to a previous group. * Press the up or down arrow keys to move from one option to another within a group. * Press the left or right arrow keys to adjust volume or gain. * Press or to select or deselect a check box. * To quit MIXERSET, press . Note ---- Some of the features mentioned above may not be available on your audio card. For example - Bass, Treble, Output Gain, and Input Gain features are available only for advanced versions of the audio card. Use the MIXERSET /? command to obtain the list of features supported by your card.
