The master controls for the mix, record, cue and FX busses are found in the top right corner of the Matrix centre section. Each
bus has its own gain pot with a Total Recall LED. The gain pots trim the signal by ±24dB and are indented in the centre at unity
g
ain.
The Mix Bus
The MIX bus has its own dedicated insert circuit which is separate from the channel routing in the Insert
Matrix. The INSERT button below the gain trim routes the bus through the MIX INS SEND and RTN
connections. By default, the return from the insert will then feed the main bus output. However, the summing
(
ΣΣ
) button below the INSERT button sums the insert return and the original bus feed together.
Note that pressing the INSERT button without anything connected to the MIX INS SEND and RTN will
leave the mix bus silent, unless the
ΣΣ
button is selected.
Note also that if the MIX INS SEND and RTN connections are not required for signal processing, pressing
the
ΣΣ
button enables the return connections to be used as a direct stereo input to the bus.
The Record Bus
The REC bus has its own dedicated insert circuit which is isolated from the channel routing in the Insert
Matrix. The INSERT button below the gain trim routes the bus through the REC INS SEND and RTN
connections. By default, the return from the insert will then feed the main bus output. However, the summing
(
ΣΣ
) button below the INSERT button sums the insert return and the original bus feed together.
Note that pressing the INSERT button without anything connected to the REC INS SEND and RTN will
leave the record bus silent, unless the
ΣΣ
button is selected.
Note also that if the REC INS SEND and RTN connections are not required for signal processing, pressing
the
ΣΣ
button enables the return connections to be used as a direct stereo input to the bus.
The REC bus can be routed to the MIX bus by pressing the TO MIX button below the
ΣΣ
button.
The Cue ST Bus
The CUE ST bus has its own dedicated insert circuit which is isolated from the channel routing in the Insert
Matrix. The INSERT button below the gain trim routes the bus through the CUE INS SEND and RTN
connections. By default, the return from the insert will then feed the main bus output. However, the summing
button (
ΣΣ
) below the INSERT button sums the insert return and the original bus feed.
Note that pressing the INSERT button without anything connected to the CUE INS SEND and RTN will
leave the cue bus silent, unless the
ΣΣ
button is selected.
Note also that if the CUE INS SEND and RTN connections are not required for signal processing, pressing
the
ΣΣ
button enables the return connections to be used as a direct stereo input to the bus.
The bus can be routed to the MIX bus by pressing the TO MIX button below the
ΣΣ
button.
When using the desk for 32-track mixdown (see Page 34), the CUE ST bus must be routed to the MIX bus.
The send signal can be auditioned on the main monitoring by pressing the AFL button below the TO MIX button. There is an
LED to the right of the button which lights to indicate that AFL is on. (See Page 38 for more on AFLs.)
