JCF Audio Latte User Manual - Notes
ever signal is present on AES 1 (or Opt if the D/A input switch is set as such) will go to the D/A
device. Obviously if the DMT section is being used in Mic or Tape mode, this is irrelevant.
For example:
AES input stream @ 176.4kHz enters on AES 2
CLK sw: 48k
D/A input: doesn't matter
Multiple sw: x2
new AES output stream available on AES 1 and AES 2 outputs (in stereo mode) @ 96kHz
Another example:
AES input stream @ 44.1kHz enters on AES 2
AES clock reference stream @ 88.2kHz enters on Opt in.
CLK sw: AES 1
D/A input: Opt
Multiple sw: doesn't matter
new AES output stream available on AES 1 an AES 2 outputs (in stereo mode) @ 88.2kHz
Notes
The configuration of the Latte can be tricky. It is designed to be extremely versatile and still do
all of the stated jobs as well as possible. Please learn the block diagram as it will certainly help
you. Flow is mostly from the left to right in the diagram.
Remember, the DMT and A/D sections can work completely independently of one another and
that means completely different speeds and clock sources.
The AES Compatible inputs are self-syncing. This is was designed to provide for simple opera-
tion and to meet the desired time-base performance.
A note about bit depth
: The D/A will make use of all data presented to it (whether it be 24 or 2
bits) from the AES compatible inputs under all conditions. The AES compatible outputs will
have 24 bits of valid data in the stream under all conditions except internally clocked 192k. This
condition will have 18 bits worth of valid data in the output stream. The lower 6 bits are un-
masked will have static junk data in them and can optionally be disregarded. No dither is used
in the Latte anywhere.
