controls to be reversed. A third parameter selects whether the headphone output channels will maintain a minimum output level or can be fully muted. In most cases the headphone output will be configured for stereo, rather than monaural, operation. The following paragraphs will describe how these controls will function in that scenario.
Level/Level Mode
When set to the level/level mode, the con- trol on the far left and the control in the center operate independently. Each control sets the output level of one channel of the headphone output. If configured to the normal mode, the control on the far left is used to adjust the level of the headphone output’s left channel. The control in the center is used to adjust the level of the right channel. If configured to the reverse left/right mode, the control on the far left adjusts the headphone output’s right chan- nel. The control in the center adjusts the left channel.
When in the level/level mode, and the mini- mum output level is set for
The Model 233’s level controls have a mechanical step (detent) that is located at the halfway (50%) position of their rota- tion range. This is intended to serve as an aid to Model 233 users. In an ideal
installation, setting the far left and center controls to their detent position will result in a comfortable headphone output level. The user, in response to a changing operating environment, can then move the controls to get more or less level as desired. The de- tent position will always remain as a useful reference point. To achieve this condition the audio level on the connected line inputs may have to be calibrated as required. This is somewhat counter to the usual mental- ity of just providing the user with whatever level comes up by default. Spending a few extra minutes “trimming” the audio levels can result in much happier and more pro- ductive talent. As previously mentioned, a level trim potentiometer is associated with each line input. These may be helpful in achieving the desired adjustment range of these two level controls. Refer to the Technical Notes section of this user guide for details.
Level/Balance Mode
When set to the level/balance mode, the control on the far left and the control in the center operate together to adjust the head- phone output level. The control on the far left adjusts the overall level of both the left and right channels. The balance control, located in the center, adjusts the relative left/right level balance. In this mode the controls operate in a manner reminiscent of a consumer audio amplifier or receiver. If set to the normal mode, rotating the bal- ance control in the counterclockwise direc- tion reduces the level of the right channel, providing the user with more perceived level in the left channel. If set to the reverse mode, rotating the balance control in the counterclockwise direction reduces the level of the left channel, providing the user with more perceived level in the right channel.
