To route the desired program to AES A follow the steps below.

1. Enter the Setup Menu. Press and hold the Battery Check button then press the Headphone Controller.

2. Navigate to the Setup Menu Function AES A Source (-10 LED on the Left Meter). Turn the Headphone

Controller to move through Setup Menu Functions. SVEN announces each function as you step through

the menu.

3. Enter the Setup Menu Function AES A Source (-10). Press the Headphone Controller to select a function.

4. Navigate among the available routing options. SVEN announces each available routing as you step

through the available options.

5. Select the routing. Press the Headphone Controller to select an option. This will exit the selected Setup

Menu Function.

6. Exit the Setup Menu. Press any key other than the Headphone Controller to exit the Setup Menu.

To switch the XLR or 10-pin Outputs from analog to digital follow the steps below.

1. Enter the Setup Menu. Press and hold the Battery Check button then press the Headphone Controller.

2. Navigate to the Setup Menu Function Digital Output (-12 LED on the Left Meter). Turn the Headphone

Controller to move through Setup Menu Functions. SVEN announces each function as you step through

the menu.

3. Enter the Setup Menu Function Digital Output (-12). Press the Headphone Controller to select a func-

tion.

4. Navigate among the available options. SVEN announces each setting as you step through the menu.

5. Select the best option for your particular setup. Press the Headphone Controller to select an option. This

will exit the select Setup Menu Function.

Limiters

When the 552 Limiters are engaged, it is nearly impossible to clip (overload) the 552 mixer. Activate

the 552 limiters by setting the front-panel “LIM” switch to either LINK or ON. This enables both the

input and output limiters and determines the behavior of the output limiter. Sound Devices recom-

mends that the limiters be active at all times. Limiters are present on both mic and line-level inputs.

The Input Limiters act solely as “safety” limiters. In normal operation, with a properly set gain

structure, the threshold of the Input Limiter will not be reached. In the event of extremely high input

signal levels, such as in high SPL environments, an Input Limiter will activate to prevent the input

signal from clipping. Without Input Limiters, high signal conditions can overload a channel and

cause distortion.

The Limiters do not alter signals below the threshold. When Inputs are linked as a stereo pair, the

Input Limiters are also linked and perform the same gain reduction equally across both inputs.

The Input limiter is active when the respective input’s Input Activity LED illuminates yellow. If the

Activity LED illuminates yellow substantially, reduce the amount of gain applied to the channel by

turning down the Trim control. See Input Activity LED for additional information.

The Output Limiters prevent the output signal from exceeding the user-set limiter threshold. In the

Setup Menu the Output Limiter Threshold can be set in 1 dB increments from +4 dBu to +20 dBu. See
