Weiss EQ1-DYN-LP Equalizer

The Weiss EQ1-DYN-LP Equalizer incorporates dynamic and linear phase EQ Programs in one unit. With exclusive digital inputs/outputs and working at up to 24 Bit/96 kHz, the EQ1-DYN-LP is the reference equalizer when it comes to digital mastering EQs.

The Weiss EQ1-DYN-LP Equalizer is designed to let you make the most of both the Dynamic and the Linear Phase EQ programs. After power-up of the Weiss EQ1-DYN-LP Equalizer, the user can chose between Dynamic (DYN) and Linear Phase (LP) modes. The workspace storage, the snapshots and the snapshot backups are fully independent between the DYN and LP parts of the Weiss EQ1-DYN-LP Equalizer. This means that all setup data are retained in any case.

EQ1-DYN

The Weiss EQ1-DYN features four freely adjustable dynamic bands, and additionally three linear bands per channel. Setting up the dynamic bands is as easy as setting a linear band. There is just one additional parameter to be adjusted by the user, the threshold control. This makes multi-band dynamic control as easy and as versatile as adjusting a parametric equalizer. The Weiss EQ1-DYN can be used as a de-esser or to give the bass an extra punch etc..

Bands 1, 2, 5 and 6 are the dynamic bands (each individually switchable to linear) and bands 3, 4 and 7 are ordinary linear bands. A dynamic band operates similar to a compressor, with two additional features:

1) The band is sensitive to signal level in its frequency range only. So when applying dynamic bass EQ, only the bass-band of the program affects the dynamic behavior. There is no cross-modulation from other bands.

2) The gain is only applied to certain frequencies, and not across the whole audio band.

3) Other modes (low-cut, high-cut, low-shelving, high-shelving) are linear (no automatic boost/cut adjustment), and behave exactly the same as in the Weiss EQ1-MK2 Equalizer.

The reason for choosing exactly bands 1, 2, 5 and 6 is the following: As the name implies, a dynamic band is sensitive to the level of the input signal. Sometimes it is desirable to first add some EQ, and afterwards dynamically add some more. Or vice versa, first do some dynamic corrections and afterwards add overall EQ, including in the corrected band. Because the EQ bands are connected in series, this is only possible if there are linear bands before and after the dynamic bands.

EQ1-LP

The Weiss EQ1-LP has the same parameter set and features as the Weiss EQ1-MK2. In addition it can be switched between minimum and linear phase behavior. Linear phase means that the delay introduced by processing is constant across the whole spectrum, unconstrained by the EQ settings. The sound, or character, of an equalizer has been said to be influenced by phase response as for example John Watkinson mentioned in Studio Sound magazine 9/97: “… much of the audible difference between EQs comes down to the phase response.” The Weiss EQ1-LP Equalizer is therefore the ideal tool for corrective amplitude adjustment, without the unwanted phase distortion added by standard equalizers.

Adding to the high resolution processing, the Weiss EQ1-LP now features an extended parameter set, significantly increasing the number of possible eq settings, as well as a new operational mode for processing stereo signals in the M/S domain (as compared to processing in the L/R domain).

The Q now reaches from a near whole-bandwidth-covering 0.20 to a needle-like 650 in 128 steps, allowing everything from subtle sound colouring to notch filter tone removal. The boost varies in 0.1 dB steps from -39dB (for notching) to +18dB. To compensate for the extremely accurate notch filter type, the frequency resolution has been doubled, now running from 14Hz to 21kHz in 12th octave steps plus including special notch frequencies such as 50 and 60 Hz and their harmonics.

A further new feature is the settable “shape” parameter for shelving filters, which has the same resolution and a similar effect as the Q parameter for the presence filter type.

Combined with the flexibility of seven independent bands per channel, the mastering engineer can now twist the transfer curve to his exact specifications.

Basic EQ1 Functions

The model Weiss EQ1-DYN-LP Equalizer features the seven identical parametric bands, i.e. all seven bands cover the entire audio frequency range. Each band has Boost/Cut, Frequency and Q/Slope knobs and operates in any of the following modes: High shelving, low shelving, peaking, high cut, low cut, bypass.

Controls, Display

There are seven times three knobs in order to have “one knob per parameter” operation. The knobs are touch sensitive to switch the LCD to display the parameters of the touched band. The LCD shows the overall frequency response, the detailed parameter values and various status information.

Snapshots, MIDI, Metering

The Weiss EQ1-DYN-LP Equalizer also features an A/B compare memory, a 128 position snapshot bank with two additional banks for back-up (can also be dumped/recovered via MIDI), a peak meter with over indicators, MIDI control for each parameter, an overall bypass switch and an overall gain control, a channel ganging switch.

Signal Processing, Connectivity

The internal processing is done at 88.2 or 96 kHz in a 40 Bit floating-point format. A very low noise filter architecture optimized for audio is used. The digital input/output are in AES/EBU format on XLR connectors. The AES/EBU output can be POW-R dithered to 16, 20 or 24 Bits.

M/S Mode

The EQ1-DYN-LP Equalizer can be switched to M/S mode which is especially useful for this dynamic mode. Other specialties are variable slope shelving filters and very high Q (up to 650) peaking filters for notching out offending frequencies.
