The Avedis MD7 addresses the features needed in op-amp based preamps with a very musical sound - without the conventional hard sounding, mid-forward timbres which are not suitable for digital recordings. Once you hear the Avedis MD7 you may want to fill up your 500-series lunchbox with them!
Where's the pad?
The MD-7 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.
What is the SEND really used for?
The SEND is an unbalanced (TS) output which is taken after the class A buffer amp, but before the discrete opamp, so you can control the level using the TRIM only. This can be used for interfacing with a variety of guitar and bass pedals and effects and going into them at the correct level without overloading (remember most operate on 9V battery). You can then come back from the effect pedal back into the DI INPUT / RETURN and use the stepped gain for setting the perfect level. The output impedance of the SEND is rated at 300 ohms – strong enough to drive many types of unbalanced inputs like guitar effect pedals.
