Technical Information:

For this recording we used two Schoeps 221B omni-directional microphones in a basic stereo placement to achieve a recording of optimum clarity and natural balance.
The orchestra was positioned left to right of the conductor :
First violins ,violas ,celli ,second violins ,and bass behind celli. The harpsichord was placed center and the soloist stood somewhat right of center to give the desired antiphonal effect with the concertmaster (left) for sectiones of the concerti where this balance lends excitement and clarification to the phrases which are tossed back and forth between the two violinists.

The hall we selected for this recording has a good music-making ambience:
a large, warm, not echoing room with height, irregular surfaces and lots of wood.
With our engineering we tried to recreate this ambience for the listener.
Our Studer Model 169 Stereo Mixer, was fed directly into the Digital Tape Recorder.
The portable Studer console is battery-powered. There is no AC and therefore no chance of hum. The power supply for the Studer 169 console is a sophisticated battery charger.

For monitoring we used an ACD / John Meyer Precision Studio Monitor (with its own Meyers Sound Lab amplification system) which is uniquely designed to reduce distortion while simultaneously increasing dynamic range.Once the balance and the dynamic level (again) were set at the beginning of the first session they were not changed throughout the recording. With digital recording there is no need to increase signal level during quite passages. Such gain-riding and / or use of peak limiters is unnecessary and highly undesirable for audiophile recordings.
