Can I use the DA-300 v.3 with a game console?

Yes, if your console has an optical or coaxial output. Use the corresponding input on the DA-300 v.3.

What headphones are compatible?

The headphone output works with most headphones (32-600 Ω). Low-impedance headphones may benefit from a higher output current.

How do I switch between inputs?

Use the input selector button on the front panel. Each press cycles through USB, Coaxial, and Optical.

Does the DA-300 v.3 support DSD?

No, the DA-300 v.3 supports PCM up to 192 kHz/24-bit but does not support DSD.

What is the power adapter voltage?

The supplied adapter is 12V DC with a center-positive plug. Always use the original adapter to avoid damage.

How do I clean the device?

Unplug the unit. Use a soft, dry cloth to wipe the exterior. Do not use any chemical cleaners or water.

Can I use the DA-300 v.3 as a preamp?

Yes, the RCA outputs provide a fixed or variable line-level signal depending on the internal jumper setting. Refer to the manual for configuration.

What causes distortion in the sound?

Distortion may occur if the input signal is too high (clipping), or if headphones have very low impedance. Reduce the volume or check the source.

Is the DA-300 v.3 compatible with iOS devices?

It can be used with iOS via a USB camera adapter, but note that iOS may limit audio output. Optical connection from an iPhone is not possible without additional adapters.

2. The computer will recognize the DAC as „TAGA Harmony DA-300" and automatically apply it as the audio output device. You can check the setting through the Control Panel->Hardware and Sound->Sound->Manage Audio Devices (Figure 1).

/Figure 1/

If the „TAGA Harmony DA-300” is not selected then locate and highlight it and click “Set Default”.

To enjoy the best sound quality, we suggest to change a default format (bit and sample rate) of your audio device to the highest available – right-click on the „TAGA Harmony DA-300” device, choose Properties and then Advanced tab and change Default Format.

1. You can now listen to the playback from the computer and DAC.
2. You can also control playback settings through the USB BRAVO-HD Audio Device Control Panel.

USB Connection

* Start "BRAVO-HD Audio CPL" from the desktop or program menu. The BRAVO-HD Control Panel will appear (Figure 2).
* If the DAC is switched on and connected to the computer the panel will display:
- The current default format (sample and bit rate) as selected in the Windows® system. Changing will affect a default format of your audio device in the Windows® system.
- The current setting of playback via ASIO (preferred bit rate and buffer size). Click to change.
- In the playback mode the current format (PCM or DSD).

Note!

* The bit rate setting should be the same as or higher than the playback file. Otherwise the bit rate or output is lower than the original.
* Setting the smaller buffer size for a higher resolution music file may cause noises or interruption. Set the buffer size to bigger and restart the playback.
