rotate the Channel Volume knob to adjust the screen brightness.

Thirty-two adjustment steps are provided for each screen from very

dim to bright to compensate for dimly or brightly lit rooms. The

actual brightness of each screen will change as the control is turned.

The default brightness for both screens is 22.

• Screen Saver: Pressing this button and then rotating the Channel

Volume knob selects the screen saver time out. Select values from 5

minutes to 119 minutes (in 1-minute increments) and from 2 hours

to 24 hours (in 1-hour increments). The default setting is 8 hours.

If the AMP1-MADIe is in operation for the screen saver time out

period and no front panel controls have been turned or pressed, the

screens will dim by a certain amount. If double the screen saver

time out period elapses without any front panel control activity, the

screens will dim further. Operating any button or control will

instantly brighten the screens.

• BNC: Pressing this button selects the BNC input as the MADI

source. The system will reclock the signal and feed it to both the

BNC and fiber outputs.

• Fiber: Pressing this button selects the fiber optical input as the

MADI source. The system will reclock the signal and then feed it to

both the optical output and to the BNC output.

• Reclocking: The reclock option can be used to extend the operation

of the unit in cases where a long cable is used before the unit, or a

large number units are attached in series before the unit. Pressing

this button toggles between On and Off. The reclocking feature is

turned off by default and allows you to specify whether the BNC or

optical signals that pass through the AMP1-MADIe are to be

regenerated (Off) or reclocked (On). If the source of the MADI

signal is connected with a long cable or fiber, reclocking will

improve the signal as it passes through. If short cables are used,

regeneration only allows more units to be connected in series.

Meter Type and Reference Menu

The Meter Type and Reference Menu allows you to define the level

meter scale, float, bar and reference.

Note:

Operating the unit with lower brightness settings and

smaller screen saver timeout values will prolong the life

of the displays.
