If de-emphasis is ‘on’ (switch 1) the RB-DHD6 will decode 50/15µs emphasis when indicated
by certain channel status bits in the incoming digital audio data. When ‘o’, no de-emphasis
is applied. The switch is ‘on’ when it is down.
Digital Input Select Button
This button is used to switch the digital input between the AES/EBU XLR connector (button
out) and the S/PDIF phono connector (button in).
