(4) Sample Rate Select - This six-position knob selects the sample rate used for A/D and D/A
conversion. Sample rates of 44.1, 48, 88.2, 96, 176.4, and 192kHz are all supported by the 2192.
The function of the Sample Rate Select knob varies according to the setting of the Clock knob.
(see #3 on page 4)
• When the Clock knob is set to Internal, the Sample Rate Select knob determines the
master clock frequency.
• When the Clock knob is set to AES/SPDIF, the Sample Rate Select knob has no effect.
(The 2192 automatically detects and uses the sample rate of the incoming AES or SPDIF
signal.)
• When the Clock knob is set to Word 1, Word 2, or ADAT, the 2192 sample rate is defined by
a combination of the external clock rate and the Sample Rate Select knob. In this mode,
the Sample Rate Select knob selects a multiple or submultiple of the external clock rate,
as follows:

(5) Clock Status lamp - When the 2192 is locked (synchronized) to a clock source, the Clock Status
lamp glows green. The lamp glows red when the clock is not locked. The clock is always locked when
the Clock knob (see #3 on page 4) is set to Internal. For the clock to be locked when the clock
 The 2192 does not perform sample rate conversion!
 When AES/SPDIF is selected as the clock source, the Sample Rate Select knob is ignored
and the 2192 instead uses the sampling rate of the incoming AES or SPDIF digital signal.
