Receive Notes:
The Delay LSB must precede the MSB. If Delay LSB is not received then it is
assumed to be 0. Increment may be used to obtain resolution down to 10us.
The Stereo mode flag checks for the correct setting of the mono/stereo switch
and produces an error message if there is a conflict.
Midi Implementation
Transmit Notes:
Delay times are transmitted as LSB then MSB then INCrement.
General Notes:
Delay times are transmitted and received correctly for 20
°
C. If the
temperature value set on the unit is different to this, then values will
automatically be adjusted.
16.0 Chassis/0v Link Removal
For both TCS-80X units the signal 0v ground is connected to the metal chassis,
which in turn is connected to the safety ground. In the unlikely event that the
link needs to be removed, or if a small amount of impedance needs to be
added to reduce earth loop currents, then proceed as follows:
Since both the audio inputs and outputs are wired fully balanced, we suggest
that you fully check that all audio wiring is correct prior to proceeding.
CAUTION: Under NO CIRCUMSTANCES should the incoming ground wire
be disconnected from the power line cord or from the internal chassis
connection as an alternative to this procedure.
•
Disconnect the mains power cord and remove the top cover from the unit.
•
Locate the green wire bolted to the chassis immediately above the 9-pin 'D'
connector which terminates onto the PCB at a point marked 'AGND' ( See
Figure 16.1 ).
•
Remove the end of this wire link from the chassis connection, fold over and
FULLY INSULATE.
•
The signal 0v (AGND) is now separate form the chassis.
The other green wire terminated onto this chassis bolt connects the output XLR
pin 1 connections to the chassis. Under NO CIRCUMSTANCES is it
recommended that this link is removed.
