AUDIO CONNECTION
CONNECTIONS
The DNS1500 offers two audio connection standards. It passes its signal to both
outputs irrespective of the input used. The standards are:
Digital SPDIF format
Digital AES/EBU format
The DNS1500 is not affected by channel status data. It will echo any such data
directly to the outputs.
LOCKING AND LOCK INDICATOR
The DNS1500 will by default lock to any AES/EBU signal presented to the rear
panel AES/EBU input. If you wish to use the SPDIF input, you must disconnect
the AES/EBU input cable, or make sure that no AES/EBU signal is present.(It is
not necessary for audio to be passing for the AES/EBU connection to be
recognised.)
The unit will lock automatically to any sample rate presented up to 100kHz. If the
input signal lies outside the industry tolerances for any of the standard sample
rates, the filter table for the nearest standard will be used and scaled
accordingly.
If no lock is possible or there is some other form of I/O error, the Bypass button
will flash slowly.
FRONT PANEL INDICATORS AND
CONTROLS
Channel Selectors
You can use the DNS1500 to process channel 1, channel 2, or both channels
presented to the active input.
Range Selector
The Range Selector concentrates the unit’s activity into the desired part of the
audio spectrum.
Level control
The Level control tells the DNS1500 how much noise is present in the input.
Band Gain controls
The Band Gain controls determine the maximum amount of processing that the
DNS1500 will apply in each band.
Activity LEDs
These offer a visual indication of the activity in each of the Bands.
Bypass
Allows you to monitor the processed or unprocessed signals.
