1. Power switch/Power LED

The main power switch for the AC2496.

The power LED (green) will light when power is switched ON.

2. WORD IN termination switch

This must be switched ON when input signals from WORD IN is to be terminated by 75 ohms.

3. LOCKED indicator

This will light up when the CLOCK switch is set to "WORD" and locked onto the external WORD clock.

4. Clock switch

This is for setup of the AC2496 operating clock.

"INT"

Operates by the AC2496 crystal.

 

 

"WORD"

Synchronizes with the external WORD clock.

 

 

5. Digital format selecting switch

This selects the digital output format (adat, S/P DIF or AES/EBU). It can also be selected to 44.1kHz, 48kHz, 88.2kHz or 96kHz (44.1/48kHz only for adat output).

6. Reference level selecting switch

This switch selects the reference level (all channels simultaneously) of the analog input (balance or un- balance). Both balance and unbalance can be selected to -20dB/-18dB/-12dB (Refer to <Notes> on the next page).

7. Analog input mode selecting switch

This switch becomes effective when the DIGITAL FOR- MAT switch is set to "adat" and if the optional Model 8355 has been installed; the signal applied to the ana- log input connector can be assigned to the desired channel. In general, these are selected in accordance to the number of BUSS OUT of a connected analog mixer.

<Notes on switching>

Always switch off the main power to the AC2496 before changing the various selecting switches. If the switches are manipulated with the main power switched on, it could create noise.

8. Blank panel

This blank panel is removed when installing the op- tional Model 8355 (AES/EBU card) or the Model 5045 (8 channel AD card). In regards to installation of the options, refer to the manual included with the cards.

9. DIGITAL OUT 1-8 connectors (Optical)

Digital equipment provided with optical DIGITAL IN are connected here. The type of digital signals (adat or S/P DIF) selected by the DIGITAL FORMAT switch will be output here.

10. WORD IN connector (BNC type)

The WORD clock signal from external digital equip- ment is input here to match the phase with digital equipment provided with WORD OUT.

11. AC IN connector

The AC cable included with the AC2496 is connected here.

12. WORD OUT connector (BNC type)

The AC2496 WORD clock signal for external digital equipment is output here.

13. Analog input connector (TRS phone jack)

This is connected to BUSS OUT (or GROUP OUT) of the analog mixer (Refer to <Note> on the next page). These connectors can accept both balanced (+4dBu) and unbalanced (-10dBV) analog signals.

T: HOT

R: COLD

S: GND

<Notes when connecting cables>

When plugging or unplugging the interconnecting cables, be sure to do so after switching off the power to the AC2496.
