Relay hard-bypass for
AES/EBU input and output
I NPUT G AIN = 0 for processing
pre-production material with
enough headroom
Choose negative I NPUT G AIN
values for full scale
recordings to create new
headroom to add harmonics
Use positive I NPUT G AIN
values for low level material
Control Elements
The A CTIVE function switches the S PECTRALIZER on or off. The
illuminated LED indicates that the processing is activated.
The software bypass also compensates for the 5 ms time
delay between processed and unprocessed signal.
The AES/EBU input and output are equipped with relay-
hard-bypass. In the event of a power failure the S PECTRALIZER is
automatically switched to hard-bypass (power failure safety)
without interrupting the data flow.
I NPUT G AIN controls the input level of the digital source. You
can boost the input gain by up to +6 dB or attenuate it by up to
-20 dB. The LC-display (see 8) shows the actual value.
Adjustment: If you are about to process pre-production mate-
rial which has not yet been normalized nor limited, you should
set the I
NPUT
G
AIN
to 0 dB.
If your source material has already been mastered and
limited it is advisable to adjust negative values for the I
NPUT
G AIN control in order to create new headroom for the proces-
sing. Keep in mind that the S PECTRALIZER adds new harmonics to
the source material. If the source is a full scale recording the
added harmonics will immediately create an overload indi-
cated by the illuminating C
LIP LEDs.
If your source material has a very low level you can use the
S PECTRALIZER ´ S I NPUT G AIN control to boost the level without making
changes to the sound. Additionally you drive the S PECTRALIZER into
an operational level to work properly.
