ITEM DESCRIPTION DETAILS
RATE
8 Green LEDs Displays the current sample clock rate as well as lock status. When SYNC SOURCE is set
to INTERNAL, both the LOCK LED and the corresponding base sample RATE LED (44.1
kHz or 48 kHz) will be lit. When SYNC SOURCE is set to EXTERNAL (AES or WORD), the
LOCK LED be lit when a valid clock signal ranging from 28 kHz to 216 kHz is present; if
no signal is present or the clock is out of range, the LOCK LED will flash to indicate that
the GENx192 is not synchronized to the clock source.
When the external clock rate falls within ± 6.0% of a nominal sample rate, the cor-
responding RATE LED will flash. When the external clock rate falls within ± 0.2% of a
nominal sample rate, the corresponding RATE LED will light solid.
SYNC SOURCE 4 position rotary switch Selects either an internal oscillator (44.1 kHz or 48 kHz) or an external clock source (AES
or word clock).
A OUTPUTS 3 position rotary switch Sets the sample rate for the A OUTPUTS. When an internal clock is used, the switch
multiplies the base rate (set by SYNC SOURCE) by either 1x, 2x, or 4x. However, when an
external clock is used, the switch can act as either a multiplier or divider, depending on
the rate of the external clock. For example, with an external 96 kHz clock, the GENx192
generates 96 kHz when the A OUTPUT switch is set to 96, 192 kHz when set to 192 (x2),
and 48 kHz when set to 48 (÷2). See CLOCK DIVISOR RANGES for more information.
B OUTPUTS 3 position rotary switch Sets the sample rate for the B OUTPUTS. Functions identically to the A OUTPUTS switch.
POWER SWITCH
Rocker switch Turns the unit off and on.
