on standby. If neither this LED nor any other LED on the front panel is illuminated then there is no power entering the unit or the internal fuse is blown. See also Remote Trigger section.

8:INPUT SIGNAL LED INDICATORS: There are 8 LEDs to indicated which input has been selected. The LED will light green when a PCM signal is present at the selected input, and red for any other signal present condition, including AC3 multi-channel signals.

9:ANALOG AUDIO OUTPUTS: The BDA-1 is supplied with one pair of gold plated RCA (phono) jacks for unbalanced (single-ended) outputs as well as one pair of fully balanced outputs on XLR male connectors. All connectors are gold plated and all output signals are fully buffered by Bryston’s discrete analog audio amplifier stages.

10:SPDIF OUTPUT: The signal present at the SPDIF output connector is the same signal that is selected as an input source. This signal is unaltered except for USB input sig- nals.

11:REMOTE TRIGGER INPUT: The BDA-1 is supplied with a Trigger input put to facilitate remote hard wired on/off control. A two pin socket mates with the CO110A-11102 bare-wire terminal block connector supplied with your BDA-1 (see illustation below-left). Supplying a DC control voltage between 3 and 12 volts (at greater than or equal to approximately 3mA) will allow you to remotely power your BDA-1 on or off. The the Remote Trigger input takes precedence over the front panel push-button switch. If a valid control voltage is initially applied to the trigger input when the BDA-1 is already powered on it may be necessary to toggle the unit OFF-and-ON once, via the Trigger input, to establish the precedence of the trigger input signal over the front panel power switch.

FIRMWARE UPDATES

BDA-1 firmware updates will periodically be available from Bryston dealers or from Bryston Ltd. directly. These firmware updates will be supplied as an executable file

(program) which, when executed on your PC, will search for available serial ports on your computer and then search for the BDA-1 before uploading and automatically installing the new firmware in your BDA-1.

1)If the BDA-1 is ON, place it in standby by pressing the POWER button either on the front panel or on the remote control. When the LED above the POWER button lights red, the BDA-1 is in standby.

2)Connect a suitable RS232 cable between your PC (sorry, but MAC’s are not supported at this time) and the BDA-1. In most cases (depending on your

BDA-1 specifications

The Bryston BDA-1 is a high-performance digital-to-analog converter (DAC) that exemplifies the brand's commitment to audiophile-quality sound. Designed for discerning listeners and music aficionados, the BDA-1 stands out with its precision engineering and cutting-edge technologies, making it a prominent choice in the realm of high-end audio systems.

One of the BDA-1's standout features is its support for a wide variety of digital audio formats. The DAC is capable of decoding formats such as PCM up to 24-bit/192kHz and DSD, ensuring compatibility with high-resolution audio files. This versatility allows users to enjoy their entire music collection, from standard CD quality to ultra-high-definition formats, without compromising on sound quality.

The BDA-1 incorporates advanced digital signal processing (DSP) that ensures minimal distortion and noise. This is crucial for achieving the clarity and fidelity that audiophiles seek. The DAC utilizes an innovative asynchronous USB interface, which allows it to bypass the limitations of traditional audio interfaces by locking the clock to the DAC rather than the source. This results in improved timing accuracy and overall sound quality.

Bryston has equipped the BDA-1 with a robust power supply, designed to deliver stable and clean power, reducing the risk of interference and ensuring consistent performance. Additionally, the unit features a dual differential output design that creates a balanced signal, further reducing noise and enhancing dynamic range. With balanced XLR outputs, as well as coaxial and optical inputs, the BDA-1 ensures seamless integration into various audio systems.

Another key characteristic of the BDA-1 is its elegant and functional design. The front panel features a straightforward interface with a clearly laid-out display, making it user-friendly while maintaining a sleek aesthetic. The build quality is exceptional, reflecting Bryston's reputation for durability and reliability.

In summary, the Bryston BDA-1 DAC is a meticulously engineered audio component that serves as a bridge between digital sources and high-fidelity playback systems. With its extensive feature set, advanced technologies, and commitment to sound quality, it is an ideal choice for those looking to elevate their audio experience to new heights. Whether for casual listening or critical evaluation, the BDA-1 is sure to impress any audiophile seeking the best in digital audio conversion.
