StudioTech 233 manual Monaural Headphone Output Level Control Operation, Sidetone Operation

When in the level/balance mode and the minimum output level is set to –40 dB, turning the level control to its fully coun- terclockwise position will place both head- phone output channels to 40 dB below maximum. This ensures that talent will never be fully “isolated” from potentially important cue signals. In addition, rotat- ing the balance control to either its fully clockwise or fully counterclockwise posi- tion will cause the applicable channel to be 40 dB below its maximum. If set to the full mute mode, turning the level control to its fully counterclockwise position will cause both the left and right channels to fully mute. In addition, rotating the balance control to either its fully clockwise or fully counterclockwise position will cause the applicable channel to fully mute.

Both of these controls have a mechanical step (detent) that is located at the halfway (50%) position of its rotation range. The balance control will typically be set to its center, detent position, making the level of the left and right channels equal. In an ideal installation, the level control can also be set to its detent position and provide a comfortable headphone output level. This will allow the user, in response to their preference or a changing environment, to adjust the level and balance controls as desired. The detent positions will always remain as a useful reference point. To achieve this condition the audio levels on the connected line inputs must be ad- justed as required. Spending a few extra minutes “trimming” the connected audio levels, rather than just providing what- ever happens to come up, should prove worthwhile. The result will be talent that is more relaxed, and an overall production that works more smoothly. As previously mentioned, a level trim potentiometer is associated with each line input. If the line

inputs are utilized as cue sources, adjust- ing the trim pots may be helpful in achiev- ing the desired adjustment range of the level controls. Refer to the Technical Notes section of this user guide for details.

Monaural Headphone Output Level Control Operation

As previously discussed, the headphone output can be set for monaural operation. This option is specifically provided so that a headphone mix mode can be cre- ated. If this has been enabled, the three front-panel level controls are used as a cue source mixer. Independent cue inputs will be assigned to the control on the far left and the control in the center channel, serving as two of the mix sources. How these two controls respond when placed in their fully counterclockwise position will depend on the configuration. By default the output level will be 40 dB below its maximum level. An alternate configuration will make the outputs mute. The control on the far right, sidetone, will always maintain the same function. It is used to add signal associated with the microphone input to the headphone output as desired.

Sidetone Operation

As previously covered in this user guide, a sidetone function can be configured. Sidetone is defined as the user’s own voice signal being returned to them as a headphone cue source. This helps the user create a more effective performance as well as possibly receiving an “on-air” or “you’re live” indication. Depending on how it was configured, sidetone audio will be sent to the left headphone output, the right headphone output, or both the left and right headphone outputs. In addition, the side tone function can be configured so that it is active only when the main output is active, or whenever the main output or
