8-channel (2 groups) HD/SD-SDI audio processor with alternate AES and analog inputs. Mix, monitor, meter and convert to AES and analog.
Product Description

The AMP1-S8MDA multi-format audio monitor is a complete, exceptionally high quality audio monitoring solution capable of monitoring audio from HD-SDI, SD-SDI, AES/EBU, and analog signal sources.

The unit is one rack-space in height (1U) and installs into an industry standard 19" wide rack.

A significant feature of the unit is the ability to process and monitor up to eight channels from an HD-SDI or SD-SDI bit stream, two sets of four AES/EBU signal pairs (balanced and unbalanced), or eight balanced analog channels.

Eight high-resolution 26-segment tri-color LED bargraph audio level meters provide accurate and instantaneous 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.

The unique acoustic design of the AMP1-S8MDA provides optimally focused sound in an Ultra Near Field tm (1 to 3 feet) environment, which allows higher SPL for the operator while reducing overall ambient sound and adjacent bay crosstalk.

The audio amplifier section features five high performance transducers driven by three power amplifiers: two amplifier/driver combinations handle midrange and high frequency information in stereo (left and right speakers), while the third center channel reproduces information below the 500 Hz crossover point (woofer speaker).

Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to magnetically sensitive equipment, such as video monitors.
