The Electrodyne 511 is a classic two-band discrete transistor reciprocal active inductor equalizer using early '70s design technology.
The 5011 is the EQ section from the 0011 in a 500 Series package. Featuring an electronically balanced input and transformer balanced output with amp circuit, and the exact same EQ circuit as the 0011.
Based on the classic dbx 905 and 3-band parametric EQ with a selectable bell or shelf type filters on low and high-frequency bands.
3 Band Class A 500 Series classic inductor-based Baxandall equalizer with Nickel/Iron/Cobalt input transformer
All discreet class A VF600 amplifiers with custom-wound cinemag input and output transformers.
Features of Extended high frequencies of 8 kHz, 10 kHz, 12 kHz, 16 kHz, and 20kHz.
Features Four bands, Reciprocal and repeatable filtering, 12 dB of boost/cut per band, EQ band 1 and 4 offer shelf/peak switching, fully discrete circuit design, High headroom +30 dB clip level.
Low band frequency range 35hz to 1khz and high band frequency range 560hz to 16khz.
Dual concentric knobs for frequency and bandwidth controls fit standard 500 series slot configuration mechanically and electrically.
Proprietary THD implementation and flexible DAW/Live plug-in control for instant recall.
Essentially Noiseless parameter changes and proprietary THD implementation.
Four Band 500 Series Eq, Selectable Hi Freq 8/12K 2 Sweepable Mid Bands 1 to 15K and 100 to 1.5K, Selectable Lo Freq 60/120Hz, 50Hz Hi Pass Switch, Peak Overload LED & a Bypass Switch.
A distinguishing feature of both the original A-Range console and Trident 500 Series A-Range EQ – 2 Space Module, is the use of faders for level adjustment, rather than rotary potentiometers. The mid frequency EQ sections are “peaking”, while the high and low frequency sections are “shelving”.
500 Series 3-band EQ with 5 Selectable Frequencies Per Band, Jensen Input and Output Transformers, and Avedis 1122 Op-amps
500 Series 10-band Graphic EQ with Transformer-balanced Signal Path, Highpass and Lowpass Filters, and 2520 Style Op-amp
The xfilter 500 is a true linked stereo EQ in the 500 series format. It gives you the expensive sound of an all class-A equalizer in a surprisingly affordable package.
