Audio Performance

SNR at 22dBu

(A-weighted)>85dB

THD+N at 22 dBu, 1 kHz

(unweighted), 0.005%

Frequency Response at 20dBu

within ± 1dB from 50Hz – 20kHz

All measurements performed using an Audio Precision System 1 Dual Domain System. Measurements performed using a

sine wave at f =1 kHz and level = 22 dBu, bandwidth = 50 Hz to 20 kHz

Connections

4-wire balanced audio. Optional RS-485 data is available to communicate with keypanels. The AIO-16 can be

plugged into either a SCSI backcard or MDR backcard.

SCSI Backcard (9000-7726-002)

Backward compatibility to existing AIO-8 breakout panels. This card carries two (2) single RS-485 data

pairs; one (1) data pair per group of eight (8) keypanel ports.

MDR Backcard (9000-7726-003)

Can be connected to 1RU, 48-port RJ-45 breakout panel or to a 2RU, 32-port DB-9 breakout panel. This

card has 16 RS-485 data pair so each intelligent keypanel can communicate with the matrix separately.
