Output Setup and Control
The 552 has stereo output bus that feeds multiple outputs. Additionally, each 552 input has its own
direct output. This output flexibility is essential for complex, multi-camera productions.
Master Gain Control
The Master Gain Control adjusts the overall output level of the left and right outputs. The gain range
of the Master Gain Control is from Off to +6 dB of gain. For most applications the Master control
should be set at the unity gain (0) position. The master gain is on a pop-up knob so it can be set and
hidden from the main surface. It is best practice to hide the Master Gain Control so that inadvertent
adjustments are avoided.
Master Outputs
The master outputs consist of three sets of connectors XLR, TA3, and Hirose 10-pin. The XLR and 10-
pin outputs are transformer-balanced, each driven from their own transformer windings for excel-
lent isolation. Each output can be independently set to Line (+4 dBu nominal), -10, or Mic level (40
dB of attenuation versus Line). The master outputs are capable of driving long cable runs.
XLR
The XLR outputs are generally used as analog outputs but can be selected for AES3. At Factory
Default, the XLR Outputs are analog. Each XLR connector is configured in the Setup Menu to output
an AES3 digital signal. See AES Digital Outputs for details. When set as analog, the XLR labeled L will
output the Left program, XLR labled R will output the Right program. Each output can be set to
output at Line, -10, or Mic levels using the adjacent level switches.
TA3
The TA3 master outputs, located above the XLR Master Outputs, are an additional set of master
outputs. These outputs are active-balanced and can be used as either balanced or unbalanced. The
output level is set between Line, -10, and Mic levels from the Setup Menu. At Factory default, the
output level of the TA3 Master Outputs is Line Level.
Hirose 10-Pin
The 10-Pin outputs are used as either analog or digital outputs. At Factory Default, the 10-Pin Out-
puts are analog. Each output is configured in the Setup Menu to output an AES digital signal. See
AES Digital Outputs for details.
The Hirose 10-Pin connector contains balanced analog Left and Right outputs. The output level is
selectable between Mic, -10, and Line levels using the level switches located directly below the con-
