MUTEC PIN CONTROL(MUTEC)
Filter Control (address 04h)
INTERPOLATION FILTER SELECT (FILT_SEL)
DE-EMPHASIS CONTROL (DEM)
Function:
Default = 0
0 - Two Mute control signals
1 - Single mute control signal on MUTEC1
Default = 0
0 - Fast roll-off
1 - Slow roll-off
Default = 00
00 - Disabled
01 - 44.1 kHz
10 - 48 kHz
11 - 32 kHz
Selects how the internal mute signals are routed to the MUTEC1 and MUTEC234 pins. When set to
‘0’, a logical AND of DAC pair 1 mute control signals are output on MUTEC1 and a logical AND of the
mute control signals of DAC pairs 2, 3, and 4 are output on MUTEC234. When set to ‘1’, a logical AND
of all DAC pair mute control signals is output on the MUTEC1 pin, MUTEC234 will remain static. For
more information on the use of the mute control function see the MUTEC1 and MUTEC234 pins in
section 4.
This Function allows the user to select whether the interpolation filter has a fast or slow roll off. For
filter characteristics please see Section 1.
Selects the appropriate digital filter to maintain the standard 15 s/50 s digital de-emphasis filter re-
sponse at 32, 44.1 or 48 kHz sample rates. (see Figure 39)
De-emphasis is only available in Single Speed Mode.
