The 1770 Loudness Monitor

LoudnessMonitor

NEW for 2017! The The 1770 Loudness Monitor is designed to insure content consistency in loudness throughout the physical plant.The 1770 Loudness Monitor is offered as a modular system consisting of a power supply, the audio interface and most importantly the display. The audio interface is placed where it is convenient for connection to either a two-channel stereo analog input or switchable to an equivalent AES digital input. Connection to the display is via a modular supplied cable. The display may then be placed in a convenient area on the operating surface. The ITU BS-1770 document offers a standard by which to monitor program content for today’s challenging audio environment. Each channel to be measured has its own separate path through low frequency roll off and mid frequency shelf equalization and into a RMS detector, which measures the energy content in that channel. The channels are then summed and presented to the indicator as a measure of the loudness content of the combined signals. Click here for more information.

The AES-402 Digital Audio Switcher

AES402

The AES-402 is a two-input switcher which can operate automatically. When placed in the automatic mode, the unit monitors the incoming audio stream and can switch to an alternate path on user-selectable error flags, loss of clock or user-defined silence. The unit can be commanded remotely or locally to switch as well.The silence sensor can be set for 30, 60, 90 and 120 seeconds of delay before switching. The selected channel status indicator can even be set to blink to indicate audio level under threshold or loss of audio. All automatic switching functions are user configurable. The unit can be set up for any combination of silence and/or error switching. There is even a setting to disable the front panel switcher and mode select buttons for tamper proof operation. Full GPIO and serial remote control is available on the rear panel. We even included addressable RS-485 remote control so that multiple AES-402 units can be controlled through a single RS-485 control pair. Click here for more information.
