INTRODUCTION
Congratulations on purchasing the Weiss Gambit Series EQ1-DYN Digital Equalizer !
The EQ1-DYN is a dynamically controlled equal-
izer. It has four dynamic bands and three linear
bands per channel, each operating at 88.2 or 96
kHz, depending on input sampling frequency
(88.2kHz processing with 44.1kHz and 88.2kHz
inputs, 96kHz processing with 48kHz and 96kHz
inputs).
A dynamic band operates similar to a compressor,
with two additional features:
1. The band is sensitive to signal level in its fre-
quency range only. There is no cross-
modulation from other bands. Some com-
pressors (like the Weiss 102 Compressor)
also have this feature, called “sidechain EQ”.
The exact centre frequency and bandwidth of
the sidechain is dependent on the centre fre-
quency and Q setting of the dynamic band.
2. The gain is only applied to certain frequen-
cies, and not across the whole audio band.
No compressor has this feature.
In addition to the dynamic operation of the bands,
the overall dynamic frequency response is dis-
played in real-time in the LC display. This is nec-
essary for the proper setup of the parameters of
the dynamic band, and it gives direct visual feed-
back on the operation of the EQ1-DYN, similar
to gain reduction meters on compressors.
Features of the EQ1-DYN include:
Processing
Four dynamic peaking filters with threshold
adjustment.
24bit digital input, internal 40bit floating-
point arithmetic, dithered output for 16bit,
20bit or 24bit wordlengths.
Display
Double logarithmic graph of the magnitude
function of the equalizer calculated in real
time
Status display showing sampling frequency,
channel status data handling, current work-
space and snapshot number and a resetable
peak-hold and over-hold per channel
Band display (activated by touch) showing
boost, Q/ slope and frequency settings for
each band
Two over-LED’s with settable number of
consecutive over-samples which cause an
“over” display combined with an over-hold
function
Snapshots
3 x 128 non-volatile snapshots where all
parameters are stored
A-B workspaces for quick comparison be-
tween two settings
Remote Control
Supports MIDI, RS-232 and RS-422 proto-
cols
Standard MIDI Continuous Controllers for
parameter remote control (including overall
gain)
Snapshot automatization with MIDI Pro-
gram Change Commands
MIDI Dump of Snapshots
