Dimensions

The DP562 occupies one rack unit and measures 45 ⋅ 483 ⋅ 305 mm (1.75 ⋅ 19 ⋅ 12 inches). Its net weight is 4.5 kg (9.9 lb).

2.2Audio Connections

The digital audio input is a 3-pin female XLR connector. The input will accept either PCM in AES/EBU format or Dolby Digital (AC-3) in IEC 1937 format (formerly IEC 958 Annex B) as specified in ATSC A/52 Annex B.

The digital audio outputs are 3-pin male XLR connectors. The outputs are PCM in AES/EBU format (5 Vp-p, 110Ω).

The analog audio outputs are balanced and use 3-pin male XLR connectors (0 dBFS = +24 dBu). The output impedance is 25Ω.

The headphone output is a ¼-inch standard audio headphone jack with +11.5 dBu maximum output into 600Ω nominal.

2.2.1Serial I/O

The DP562 has a rear-panel RS-232 port. This port is used for software upgrades and can also be used to control most of the functions of the DP562. The unit must be in Remote Control mode before it will accept commands through the Serial I/O port. Remote Control mode is enabled in the User Menu, which is entered by holding down
