Eq And Filters - Sony OXF-R3 Brochure & Specs

eq and filters

The standard EQ is extremely powerful, with the gain of all bands fully
adjustable over a range of ±20 dB and with Q adjustable between 0.5
and 16. Frequency ranges are carefully selected for each band,
creating an extremely 'musical' device equally capable of delivering
subtle or radical tonal changes with any source material.
The OXF-R3 permits EQ parameter changes to be made smoothly and
evenly with an analogue console-like feel. This glitch-free performance
is made possible by real-time parameter interpolation that prevents
abrupt 'steps' in the response of the console's EQ sections.
The Low and High bands can switch between Bell and Shelving
profiles. In the Shelving mode, the Q control changes to provide an
overshoot/undershoot control mimicking the response of popular
outboard EQ devices. The console is supplied with two EQ memories
for every channel, selected from the A and B switches on the panel.
These memories allow the operator to experiment, without losing the
previous settings. During mixing an alternate EQ can be recalled
either manually or by the console automation.

As standard, the OXF-R3 offers five-band, fully parametric, EQ with
separate HP and LP filter sections on Full input channels. The Stereo
Return channels have three-band EQ. Several modes are supported,
featuring different relationships between factor and gain. The optional
DMSK-R3001 Software emulates the GML 8200 equaliser. The EQ and
filters are controlled from the dedicated 'Equaliser & Filters' panel
and the resulting frequency curve is displayed on the associated GUI.
The panel is designed to be very intuitive and fast to operate, with
individual switches and rotaries for every EQ and filter function.
The EQ Range control allows the limits of cut and boost on each
channel to be adjusted between ±20 dB and 0 dB. As with all other
controls on the console, this adjustment is completely glitch-free
which permits complete EQ settings to be ramped in and out. The EQ
Range control also allows the cut and boost limits to be reduced
thereby increasing the resolution
for ultra-fine adjustment.
The High and Low Pass filters on
the Full channels are also highly
versatile. The cut-off frequency
is continuously variable and
the filter slope can be selected
between 6 dB/octave and 36
dB/octave in 6 dB steps.
Optional DMSK-R3001 Software EQ mode GUI
Dynamic automation of the EQ and filters provides new creative tools
for the studio. For example, the operator can 'de-ess' a vocal by
dynamically automating the high frequency band against time code.
