Tascam DS-M7.1 owner manual Inserts, Monitor connections

3 – Connections

Error	Meaning	Appropriate action to take
number
7	Frequency error	The master clock is not a recognized frequency (e.g. 32 kHz). Check the master set-
		tings and correct, if necessary.
8	AES/EBU preamble error (normal)	At normal sampling frequencies, the preamble of the AES/EBU signal acting as the
		clock source cannot be read by the DS-M7.1. Check and correct settings on the clock
		master.
9	AES/EBU preamble error (high-speed)	At high sampling frequencies (88.2 kHz and 96 kHz), the preamble of the AES/EBU
		signal acting as the clock source cannot be read by the DS-M7.1. Check and correct
		settings on the clock master.

Inserts

Either analog or digital insert units can be connected to operate after the BUS/RTN switch. These are selectable pre- or post- the Input Summing Router.

These inserts can be pre- or post- the input summing router (placed between the inputs and the RTN/BUS selector switch) and always pre- the RTN/BUS switch. See the block diagram at the end of this man- ual for details.

Either AES/EBU digital devices, or analog (standard +4dBu balanced) may be used here. Note that when making connections to an analog insert unit, because of the nature of the connectors used, two connections need to be made, one for input and one for output.

After the connection has been made, you should set up the insert as follows:

1Press the INSERT key so that the screen shows something like:

[INSERT]

State DISABLED

Mode POST SUM Return ANALOG

2There are three parameters. Use the cursor keys to select them. First, select whether the insert loop is enabled (ENABLED) or dis- abled (DISABLED).

3Next, select the position of the insert loop, as described above: either PRE SUM or POST SUM (i.e. before or after the input summing router).

4Finally, set the Return type: ANALOG (analog) or DIGITAL (digital).

Monitor connections

There are two sets of monitor connections, analog and digital.

The analog connections are standard balanced +4dBu connections, and the digital outputs are in AES/EBU format.

NOTE

The sampling frequency output from the digital moni- tor outputs is the input frequency. If you are mixing a high sampling frequency project, you must therefore make sure that your digital monitoring setup can han- dle these frequencies, or use the DS-M7.1’s analog mon- itoring ports.

The analog and digital signals are output in parallel, and there is no switching between them.

TIP

The AES/EBU monitoring signals can be used in parallel with the analog monitoring signals to drive a suitably- equipped meter bridge.

However, there is one setting that can be made for the AES/EBU digital ports; the “pick-off” point for the monitoring.

This can be set so that all the downmix, bass manage- ment and delay settings, together with all muting and soloing and level settings described in “Other moni- toring settings” on page 17, are ignored, or so that these settings take effect through the digital port. This affects the digital outputs only—the analog out- puts will always reflect these settings.
