OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-MK2 OPERATION
Daniel Weiss Engineering Ltd., Florastr. 42, CH-8610 Uster Page 14 of 26
Dither
The EQ1 is able to apply shaped dither noise to
remove distortion when re-quantizing from 24bit
to 16bit or 20bit output word length (see
TECHNICAL DATA for dither specifications).
To toggle dither on/off, press key D twice.
Word Length
To set output word length, press key D and
choose either 16bit or 20bit.
Auto-Blacking
If auto-blacking is activated by marking the “0 IN
à 0 OUT“ option, dither will be turned off if the
input signal is digital zero for more than 256 con-
secutive samples. As soon as the input signal
changes, dither will be turned on again. This en-
sures that breaks between programs are still
digital zero, even if dither is activated.
Display Resolution
The magnitude of the overall frequency response
of the EQ1 is drawn on the LC display. This im-
mensely facilitates filter parameter adjustment
because it takes one look to see what the equal-
izer is doing instead of having to work it out from
the parameter values.
To obtain the maximum benefit from the graph,
set the vertical display resolution to a range that
just covers your settings. There are four ranges
available:
± 6dB, ± 12dB, ± 18dB, ± 24dB
To change the display resolution, press the
“menu” key, then select “Display”. Choose a
range that suits your curve and press the “menu”
key again to return to the status display.
LCD Contrast
To change the display contrast, press the “menu”
key, then select “Display”. Adjust contrast with
the “gain/ data” encoder.
EQ Bypass
The EQ1 can be completely bypassed with the
green “bypass” key below the mains switch. If the
“bypass” key is lit, the EQ1 is absolutely transpar-
ent, making the output signal bit equal to the
input signal.
While bypass is active (key is lit), the EQ1 works
in preview mode. This allows you to change pa-
rameters without actually affecting the audio sig-
nal. The frequency curve is drawn outlined over
the flat bypass curve, so you still get the advan-
tage of the graph when modifying parameters.
As soon as bypass is deactivated, the outlined
curve takes effect.
Remote Control
All band parameters as well as control settings
can be set externally.
To see remote control status refer to the status
display.
Protocol
To select a remote control protocol, press key C
from the status display menu. Select either “RS
232”, “RS 422” or “MIDI”. This will determine
which port at the rear of the EQ1 is active. The
other inactive ports will be ignored.
Press the “menu” key to return to the status dis-
play if you do not want to change remote on/ off
status.
When selecting a port other than MIDI you have
to specify the baud rate. Refer to the remote
control software manual for correct settings. The
set baud rate is displayed to ensure proper set-
up.
Channel
To change the remote control channel number,
press key C (adjacent to the remote control
field). Use the “gain/ data” encoder to select a
value between 1 and 16. Press the “menu” key to
return to the status display.
The EQ1 does not support poly-mode (listening
on all channels). Select the same channel on the
