Avedis Audio MA5 The MA5 was created to fill the need for a high-quality microphone preamplifier with the characteristic sound of early ‘70s British Class-A consoles. The re-engineering in the creation of the MA5 stemmed from years of experience restoring both American and British modules, deeply rooted in classic transformer-balanced, discrete electronics. Only the best and most suitable components are used throughout, regardless of cost, to attain the best sound. Over a year was spent on the MA5- not only on the engineering side of the design, but also in extensive sound evaluation with observation of specific settings, gain structures, and key components. We have always believed that our ears' sensitivity coupled with experienced judgment of sound is still unparalleled- even with some of the best audio test analyzers which we own and use. In the end, it is our ears we are trying to satisfy. The MA5’s full and open sound is due to a rich harmonic content, particularly in the very low frequencies- even down to, and below, 10Hz. The clear mids and smooth highs come through without sounding dull or smeared. Features: - Standard 500 series modular size 1.5" x 5.25" - Single-ended Class A amplifier - UK-made Carnhill/St Ives input transformer - Custom-designed Jensen output transformer - Stepped-gain rotary switch in 5dB steps - Output level pot for trim and mute - LED-lit pushbuttons - 28kHz feature brings out high frequency detail - Custom-made Marconi-style knobs - High headroom & CMR, low noise design

Avedis MD7 Mikrofonvorverstärker - Diskreter Class-A 500er Mic-Preamp mit DI Input/Return, HPF, Phase, 48V - The MD7 addresses the features needed in op-amp based preamps and, more importantly, with a very musical sound without the conventional hard sounding and mid-forward units which are not suitable for today’s digital recordings. The MD7 does not have a PAD and doesn’t need it. The usual place for the PAD in a conventional circuit is before the input transformer and the big reason why we’ve heard over the years that it changes the sound. With the MD7, the full range and dynamic signal hits the Jensen input transformer first, adding it’s own signature to the sound. The MD7’s additional class A amplifier buffers the INPUT TRIM control for even better adjustment of level compared to a fixed PAD of other conventional microphone preamps. We took a long time working on the DI to make it n important part of the MD7’s sound, rather than just an added feature. The input impedance is 10M ohm meaning that you can connect all kinds of instruments, including sensitive high end piezo pickups which require a wide bandwidth and a very high input impedance. If customized level control is needed for the DI circuit, there is a small hole at the side of the unit’s cover which can access a small trim potentiometer. You can adjust the level’s using a small flat head screwdriver.
