SRC selftest

To verify correct operation of the SRC, perform an SRC selftest. During selftest, an
internally generated sine wave is passed forward and then backwards through all
64x64 channels of the SRC (running two conversions, from 96kHz => 88.2kHz
=> 96kHz)
To enter SRC selftest mode: Press Recall , move to ☼ Function , move to

☼ 11 , press OK , turn the encoder until the seven-segment display shows 03
("SRC selftest") and press OK .
The resulting data is output on the headphones where it can be verified by

listening to it. The SRC works correctly if a clean, non-distorted 1000Hz sine
tone can be heard on all channels.
Use ☼ Ch to listen to the appropriate channel. The output volume can be
adjusted using ☼ Vol.
The resulting data is also output on MADI optical (channels 1-32) and MADI

coaxial (channels 33-64) as two 96kHz/32ch streams, clocked by the internal
clock of the multiverter. You can use any signal meter to check the result; the
output level should be -20dB on all channels.
To exit SRC selftest mode, press the
