Expansion input channels
The DTP CrossPoint accepts 8 expansion input channels (see figure 75).

Connection
No special setup is required; just connect the two devices. By default, the DMP 128 is
the primary unit and the DTP CrossPoint is always the secondary unit. If you have trouble
connecting the matrix switcher and the DMP 128, check that the DMP 128 is set to be the
primary device.
Optimizing the Audio
Program material that you are familiar with is preferable for the following procedures,
otherwise, pink noise can be used.
TIP:
The Extron VTG 300 or VTG 400 is recommended to provide the pink noise.
Input Clipping and Clipping Meters
Audio clipping is a form of distortion that occurs when the signal peaks (or excursions)
exceed the limits of the circuit, cutting off the excursions of a signal. This condition gives
audibly undesirable results. While it is difficult to clip the audio signal within the DSP audio
signal chain, it is extremely important that the audio signal is not clipped before the input to
the switcher. Once audio is clipped at the input, there is no remedy further down the signal
chain. However, if audio clipping occurs at the output of the DSP that is not a result of
clipping at the input, this can be addressed in the DSP audio signal chain.
