Digital recording from an external digital device

In addition to multirecording by connection to a digital mixer as explained in the separate “Quick Operation Guide” manual, the following explains the direct digital recording method by connection to external digital equipment (CD, MD, DAT, adat, etc.).

When recording digital signals from an external digital equipment, digital signals to be input to the [DATA INPUT] connector of the D2424 must be setup for “S/P DIF” (S/P DIF digital signals) or “adat” (adat digital signals) in the “Digital Input Setup” menu of the D2424 SETUP mode.

At the same time, the digital-in clock (Sync mode/async mode) should also be selected and setup for either sync with external digital signals or with the internal clock. Digital recording can be done on the currently active program, and “Setup for digital inputs” will be effective on all programs even when multiple number of programs are currently setup.

Connecting external digital equipment

1. Interconnect the [DATA INPUT] connector of D2424 and [OPTICAL OUT] (or adat OUT) connector of the external digital equipment with an optical cable.

Depending on the digital signal (S/P DIF or adat) to be recorded, the [DATA INPUT] connector will function as explained below.

<Notes on interconnecting>

When using the D2424 [DATA INPUT] connector, it must be set for either S/P DIF digital signals (optical) or adat digital signals via "Setup of digital inputs" in the SETUP mode. The connector type is the same for S/P DIF digital signals and adat digital signals but information content of the digital signal is different. Also, depending on the selected digital signal, each [DATA INPUT] connector will function as explained below.

<When recording S/P DIF digital signals> <When recording adat digital signals>

[DAT INPUT 1-8] only can be used.

By setting the SETUP mode “Setup of digital in- puts” to "SPDIF Async" or "SPDIF sync," S/P DIF digital signals that are input to [DATA INPUT 1-8] will be assigned to tracks 1 and 2 of the D2424.

Tracks 1-2

[DATA INPUT 1-8], [9-16], [17-24] can all be used. By setting the SETUP mode “Setup of digital in- puts” to "adat Async" or "adat Sync," adat digi- tal signals input to each input connector will be assigned to each track of the D2424.

Tracks 17-24 Tracks 9-16 Tracks 1-8

			DATA

adat digital signal

<Important!>

Be sure to input a digital signal (S/PDIF or adat) of the same sampling frequency as that used on the recorder.

<Note>

Connecting the recorder to an external digital device via both digital input and output jacks may generate a digital loop.

*If the connected external device has only a COAXIAL (RCA pin) jack for digital output, use an optional Fostex COP-1/96k (optical/coaxial converter).
