JCF Audio Latte User Manual - Fcc Compliance:
3. Q: Why the jumper configurable everything?
A: The jumpers come configured such that most users will not have to adjust them for nor-
mal usage. A concerted effort has been made to make certain parameters adjustable to acco-
modate more complex setups without confusing and cluttering the front or back panels with
controls that most users will not have to address.
4. Q: Why the same electronics block for the D/A as the Mic and Tape circuits.
A: Why not? Every D/A construction (with a few exceptions) will have to utilize an ampli-
fier block (or many) to interface with the outside world. After visiting a great number of com-
binations of modern opamp configurations, discrete opamps, tubes, etc., the 3 transistor pre / 4
transistor line amp used in the Latte was employed. This combination of amplifier stages (or
very similar ones) were used for years in tape machines and certain microphone preamps and
accomplished the task elegantly and with a small number of components. The DMT sections’
usages as a microphone preamp or tape machine repro were secondary to achieving an elegant,
simple, and time-proven amp section for the D/A function. All of the additional functions of
the Latte presented themselves and were then implemented with great ease and without cram-
ming additional electronics inside the unit.
