JCF Audio Latte User Manual - Rear Panel
be taken in this mode to not connect the output of the A/D in a direct or indirect fashion back to the D/A such that a
feedback loop exists. The extremely high levels and spikes generated by doing this can damage the A/D converter
section.
D/A input
- This switch controls the input signal to the first AES receiver. AES selects the signal from the AES 1
input and Opt. selects the input from the TOSLINK jack. Whichever signal is selected is passed on to the D/A con-
verter section in all modes of operation.
CLK and Multiple
- This switch selects the clock source for the AES compatible output section of the A/D or
sample rate converter as follows:
• All operation of the A/D section of the Latte at 44.1kHz and multiples thereof require external clocking.
• 48k refers to the internal clock which will run the AES compatible outputs @ 48k or multiples thereof (depending
upon the setting of the multiple switch).
• The AES 1 setting will derive the clock source for the AES compatible outputs from the AES 1 input. In this setting
the recovered sample rate will be the sample rate of interest and the setting of the multiple switch has no bearing. In
this mode the D/A section and the A/D section will run in sync with one another.
• The AES 2 setting will derive the clock source for the AES compatible outputs from the AES 2 input. In this setting
the recovered sample rate will be the sample rate of interest and the setting of the multiple switch will have no bear-
ing.
• The Opt. setting will derive the clock source for the AES compatible outputs from the Opt. input. In this setting the
recovered sample rate will be the sample rate of interest and the setting of the multiple switch will have no bearing.
• The Multiply switch will select X1-48k, X2-96k, or X4-192k only if the CLK source is the internal 48k. With all other
sync sources, the setting of this switch is ignored.

MIC/Tape
- These inputs are meant for low impedance microphone signals (~200
Ω
) or low impedance tape heads
(between 2µH and 10µH). The input Impedance at this point is dependent upon the adjustment of the input loading
pot and actuation of the pad
AUX outputs
- These are the jumper configurable outputs of the DMT section of the unit. They can utilize any
combination of the following features
• Pin 2 or 3 hot
• Balanced or unbalanced operation
• Line level output or pre-attenuator low level preamp output
