552 User Guide and Technical Information

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-
