Frequently Asked Questions - DA824 YAMAHA

How do I connect the DA824 to a digital audio device?

Install an appropriate mini YGDAI I/O card (e.g., MY8-AE for AES/EBU, MY8-AT for ADAT) into the SLOT. Then connect the digital audio device to the card using the correct cable (AES/EBU 25-pin D-sub or ADAT optical). Ensure the wordclock is synchronized.

What wordclock source does the DA824 use?

By default, the DA824 locks to the wordclock derived from the digital audio inputs on the SLOT. If a valid signal is present at the WORD CLOCK IN BNC connector, it will use that instead. The LOCK indicator confirms synchronization.

How do I set the maximum output level?

Inside the DA824 are eight output-level switches (one per channel) that can be set to +24 dB, +18 dB, +15 dB, or +4 dBV. Refer to your Yamaha dealer for adjustment.

What is the proper power-on sequence?

Turn on equipment in this order: sound sources, mixer or recorder, DA824, then power amplifiers. Reverse the order when powering off to avoid thumps and clicks.

Can I mount the DA824 in a rack?

Yes, the DA824 is 2U high and can be rackmounted. Ensure at least 10 cm of free space behind for ventilation, and avoid placing it next to heat-generating devices like power amplifiers.

What should I do if the LOCK indicator flashes?

A flashing LOCK indicator means the unit is not synchronized to the wordclock source. Check that the digital audio device is transmitting a valid wordclock and that the connection is secure. Also verify termination settings.

How do I clean the DA824?

Use only a soft, dry cloth. Do not use benzene, thinner, cleaning detergent, or chemical cloths, as they may damage the finish.

What digital I/O cards are compatible?

The DA824 uses optional mini YGDAI cards. Available cards include MY8-AT (ADAT optical), MY8-AE (AES/EBU 25-pin D-sub), and MY8-TD (Tascam TDIF-1). Check the Yamaha website for the latest compatibility.

How do I terminate the wordclock?

Use the WORD CLOCK 75Ω ON/OFF switch on the rear panel. In bus or daisy-chain distribution, termination is applied only at the last device. With a distribution box, termination is on at each device.

What should I do if the unit emits smoke or unusual odors?

Immediately turn off the power, disconnect the power cord from the AC outlet, and contact your Yamaha dealer for repair. Do not continue using the unit.

Cautions

• If this device is to be mounted in an EIA-standard rack, leave the back of the rack open and make sure that it is at least 10 cm away from walls or surfaces. Also, if this device is to be mounted with devices that tend to generate heat, such as power amplifiers, be sure to keep an adequate gap between this device and the heat-generating devices or install ventilation panels to prevent high temperatures from developing inside this device. Under these conditions these devices can be rackmounted. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), or even fire.
• Use the DA824 in an environment where the temperature is between 10^ and 35^ (50°F and 95°F).
• Turn off audio devices when connecting them to the DA824, and use only the cables specified in the relevant owner's manuals.
• If you plan not to use the DA824 for a long period of time, remove the power cord from the AC outlet. Leaving the DA824 connected is a potential fire hazard.
• Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean the DA824. Use only a soft, dry cloth.
• If the DA824 is stored in a cold place (e.g., overnight in a car), and then moved to a warmer environment, or the temperature rises sharply, condensation may form inside the DA824, which may affect performance. In such cases, the DA824 should be allowed to acclimatize for about one hour before use.
• When the wordclock source is changed, the DA824's analog outputs may produce noise, especially if an MY8-AT I/O card is installed, so turn down your power amps beforehand. Likewise, when changing the wordclock source on the wordclock master device (e.g., AD824 or DME32), turn down your power amps beforehand, or turn off the DA824.
• When setting up the product, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Even when the power switch is turned off, electricity is still flowing to the product at the minimum level. When you are not using the product for a long time, make sure to unplug the power cord from the wall AC outlet.

Interference

The DA824 uses high-frequency digital circuits that may cause interference on radio and television equipment located nearby. If interference is a problem, relocate the affected equipment.

5 Wordclocks

About Wordclocks

For correct operation and digital-to-analog processing, it is essential that the DA824 is wordclock locked to the digital audio device transmitting the digital audio signals. Normally, the DA824 locks to a wordclock signal derived from the SLOT digital audio inputs, but when a usable wordclock signal is present at the WORD CLOCK IN connector, this is used instead.

The LOCK indicator lights up when the DA824 is locked to the wordclock source and synchronized to the digital audio signal. It flashes if the DA824 is not synchronized to the digital audio signal.

Note: When the wordclock source is changed, the DA824's analog outputs may produce noise, especially if an MY8-ATI/O card is installed, so turn down your power amps beforehand. Likewise, when changing the wordclock source on the wordclock master device (e.g., AD824 or DME32), turn down your power amps beforehand, or turn off the DA824.

Wordclock Hookup Examples

In this example, the DA824 sources the wordclock signal from the SLOT digital audio inputs.

graph TD
    A["Digital Audio Device (DME32, 02R, D24, etc.)"] -->|Digital I/O| B["DA824"]
    B --> C["MY8-xx"]
    C --> D["DA824"]

    E --> F["MY8-xx"]
    F --> G["DA824"]
    G --> H["Wordclock out (BNC)"]
    H --> I["WORD CLOCK IN"]

In this example, the DA824 sources the wordclock signal automatically from the WORD CLOCK IN connector.

Wordclock Termination

For correct and reliable operation, wordclock signals distributed via BNC cables must be terminated correctly. Termination is typically applied at the last device, although it depends on the distribution method being used. The DA824's WORD CLOCK 75Ω ON/OFF switch allows the DA824 to be connected in a variety of ways. The following examples show three ways in which wordclock signals can be distributed and how termination should be applied in each case.

Wordclock Distribution Box

In this example, a dedicated wordclock distribution box is used to supply a wordclock signal to each device individually. Termination is applied at each device.

graph TD
    A["Wordclock master"] -->|WC OUT (BNC)| B["Wordclock distribution box"]
    B --> C["Device-A\nTermination = ON\nWordclock slave Wordclock"]
    B --> D["Device-B\nTermination = ON\nWordclock slave Wordclock"]

    B --> F["Device-D\nTermination = ON"]
    C --> G["End"]
    D --> G
    E --> G
    F --> G

Bus Distribution

In this example, the wordclock signal is distributed via a common line. Termination is applied at the last device only.

graph TD
    A["Wordclock master"] -->|WC OUT (BNC)| B["Device-A"]
    A -->|WC IN (BNC)| C["Device-B"]
    A -->|WC IN (BNC) WC IN (BNC) WC IN (BNC)| D["Device-C Device-D"]
    B -->|Termination = OFF\nWordclock slave Wordclock slave Wordclock slave Wordclock slave| E["End"]
    C -->|Termination = OFF\nTermination = OFF Termination = ON| F["End"]

Daisy Chain Distribution

In this example, the wordclock signal is distributed in a “daisy-chain” fashion, with each device feeding the wordclock signal on to the next. Termination is applied at the last device only. This method of distribution is not recommended for larger systems.
