AUDIO CONNECTIONS AND INDICATORS
Connections
The
DNS1000
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
DNS1000
is not affected by channel status data. It will echo any such data
directly to the outputs.
Indicators
The
DNS1000
rear panel offers two pairs of
LED
indicators. The upper pair display
information relating to audio signal sample frequencies. The lower pair show
which input is in use.
■
Frequency LEDs
If the “44”
LED
is lit, the input sample rate is 44.1kHz. If the “48”
LED
is lit, the
input sample rate is 48kHz. If both
LEDs
are lit, the input sample rate is 32kHz.
If one or both
LEDs
are flashing, the
DNS1000
is receiving a signal that is close to,
but outside the industry tolerances for that sample rate. The unit will operate
correctly, but with the filterbank frequencies scaled by a corresponding amount.
■
Input LEDs
If the
AES LED
is lit, the
DNS1000
is receiving data through its
AES/EBU
input. If the
SPDIF LED
is lit, the unit is receiving data through its
SPDIF
input. If data is
presented to both inputs simultaneously, the input that was first locked to audio
will retain priority.
If both
LEDs
are flashing alternately, the
DNS1000
is unable to detect a valid signal
and can not lock to either input.
