Switches 5 and 6
Channel Mapping
For Disembedding
Groups
The following table shows how combinations of setting these two switches affects
disembedding channel mapping.
Audio Levels
Professional audio equipment has much higher levels than consumer equipment: a 0 VU
reading corresponds to +4 dBu. Connecting a professional +4 dBu device to a consumer
audio input (
-7 to -8 dBu)
may produce dangerous overloading, whereas the output of a
consumer device probably does not have sufficient power to drive a professional audio
input. With consumer and semi-professional audio equipment, a VU reading of 0 dB is
typically referenced to -10 dBV, which is equivalent to -7.78 dBu.
