TSM Detection on TSM Detection (Top/Sub-Mismatch)
NOTICE The "TSM Detection" is set to "on" by factory default. If it is changed to
"off" this setting is kept also after the D12 has been powered off.
In "Dual channel mode" all four pins (TOP and SUB pins) of the output
connectors are driven. This could cause damage to TOPs when a SUB
configuration is selected on the respective channel.
The D12 monitors the current through the different output pins and
detects if a wrong cabinet type is connected.
The error message "Top/Sub-Mismatch" is displayed on the LCD and
the respective channel is muted.
If the pin assignment of the used wiring differs from the d&b standard,
"TSM Detection" can be set to "off" in order to avoid the detection of
an error.
