General AMP-S8 Features

Features

The

AMP-S8

audio monitoring products are a complete, exceptionally high quality

SD-SDI/HD-SDI, AES/EBU

and

Analog

stereo audio monitoring solution. The

AMP-S8

comprehensive monitoring features are available in either a

compact one (

1U AMP1

) or two (

2U AMP2

) rackspace cabinet. A significant feature is the ability to process and monitor up to

eight channels from an

SDI

and/or

SD-SDI

bitstream, two sets of four

AES/EBU

signal pairs (balanced and unbalanced), or

eight

Analog

channels. Eight high-resolution 53-segment tri-color LED bargraph audio level meters provide accurate and instanta-

neous visual level monitoring at a glance. A convenient high-contrast LCD display on the front panel shows the user settings and
status (as currently selected), type of signal, channel selection, mute status, and alternately, phase/correlation. Input presets may be
configured and easily recalled by the user.

Additionally, the unique design of the

AMP-S8

provides optimally focused sound in an Ultra Near Field (1 to 3 feet)

environment, which allows higher SPL for the operator while reducing overall ambient sound and adjacent bay crosstalk.

There are four different configurations which vary according to

SDI

input type and configuration; the

AMP-S8DA

(

SDI

), the

AMP-S8SDA

(270 Mbps

SDI

), the

AMP-S8HDA

(1.5 Gbps

HD-SDI

), and the

AMP-S8MDA

(270 Mbps

and

1.5 Gbps
