The Model 535 Dual Graphic Equalizer is a studio quality product which has wide application in recording, sound reinforcement, radio and TV production, and high fidelity music systems. It uses Harris HA 4741-5 Op Amps. It can be modded, if you wish, by switching out these op-amp ICs. Some people online have done this with good results. However this item is 100% vintage and original. The system is designed to operate at any nominal level from as low as -20dB Ref. 0.775 V allowing its use with low level mixers, high or low impedances, and balanced or single-ended circuits. The Model 535 provides 12 dB of boost or cut at each of its 10 frequencies which are centred at ISO l-octave increments from 31.5 to 16 kHz. The positions of the control arms of the vertical, stepless controls provide a graphic representation of the response curve selected. The filters are active, minimum phase, 2-pole synthesized LC networks, whose skirts properly combine for minimum ripple and phase shift when used in combination. A front panel control adjusts the gain from -10 dB to +20 dB. Bypass switches permit switching the equalization out for A-B test. An optional (SC-1) security cover may be installed to protect all operating controls against inadvertent disturbance or tampering in fixed installations. If you are using the amp with a modern high impedance system, you need to put a 600 (or 620) ohm resistor across the output terminals in parallel with the load. A printed copy of the manual is included. The item is in overall good condition, but as with all vintage audio equipment, the controls may need application of some Deoxit to function at their best after being sat unused for so long.

MP73EQ-V2 Microphone Preamp and Equaliser This classic high-end single channel microphone preamplifier and equaliser is based on a Neve 1073, and allows for the use of a wide variety of microphones with its impedance selector on the input. Onboard EQ and Filter The MP73EQ has a switchable high pass filter, which lets you cut out the mud and other useless low-frequency noise that can cloud up your sound. Shelving high and low-frequency EQ controls with selectable cutoff frequencies give you an enormous range of tone, and semi-parametric mid control lets you dial in frequencies from 360Hz all the way up to 7.2k – perfect for fine-tuning your sound. Solidly Built, New Look This preamp is built in a proper way without integrated circuits in the signal path. Transformer balanced inputs and outputs, 3-band EQ with good old frequency selection and adjustable bass filter. The MP73EQ also has several features that are rare in this price range, such as selectable impedance on the mic preamp, separate mic and line inputs, and a DI in front that is worth the price alone. Classic “English” Sound The MP73EQ’s saturation (harmonic density and richness) and EQ curves are like the classic 1073. The saturation in the low end has the same sound signature as the classic mic pre. It is also very quiet and has alot of gain headroom. Fully Discrete Signal Path. Individual transformers for input and output. High/mid/low 4 band inductor EQ. The chassis is made from high quality steel to provide extra shielding against magnetic and RF interference. Mic impedance is switchable to choose the correct impedance to your mics. You May Also Like. Alctron MP73A 500 Series Microphone Preamplifier.

Founded in 1985 by Rupert Neve. Focusrite’s first contracts included a commission from Sir George Martin. To build extensions to Air studios. Consoles, initially the vintage recording console in Martin’s Air Montserrat. Studio in the Caribbean specifically a no-compromise microphone preamplifier and equaliser. This is a fantastic sounding professional equaliser! Condition is very good and it is full working. Even if switched to standby, or with all EQs neutral, the sound is getting warmer and rounder (transformers). For mastering, I recomment to use a mid/side-processing (Voxengo MSED PlugIn or similar). I have never heard so sparkling highs and tight bass like from this EQ. I also have the Focusrite RED-PlugIns and compared them to the real thing, but there is a huge difference. Even if the PlugIns are very good, the Hardware sounds much more open and the bass is amazing tight. Comes with powercord and in safe packaging.
