Overview
JDS LABS ATOM DAC+ WITH UPGRADEABLE FIRMWARE
JDS Labs Atom DAC+
Give your headphone amplifier or powered-speaker setup a dedicated digital source. JDS Labs Atom DAC+ converts USB or optical audio to a stereo RCA line output in a compact desktop chassis.
USB-B / Optical
Digital Inputs
RCA
Line-Level Output
Up to 384 kHz
USB PCM Format
15 VAC
External Adapter Requirement
USB and optical sources, one RCA output
Connect a computer through USB or use TOSLINK for compatible digital sources. USB supports high-resolution PCM up to 32-bit/384 kHz; optical supports PCM up to 24-bit/192 kHz, subject to the source device.
A dedicated stage for your audio system
The ES9018K2M DAC works with a precision I/V output stage and an external AC power supply. Upgradeable XMOS firmware provides an update path, while automatic standby reduces activity when audio is idle.
Keep the Exact Model and Signal Path Clear
Atom DAC+ uses USB Type-B or optical input and RCA line output. Headphones require a separate amplifier. Use its specified external 15 VAC supply rather than treating it as a 5 V USB-powered device.
Choose the Connected Equipment for Its Actual Role
Match the product’s stated input and output connections to the source and destination. Keep microphone preamps, digital converters and headphone amplifiers in their appropriate roles, checking cable wiring and power requirements before completing the recording or listening chain.
Plan Power and Gain for the Complete Setup
Use the model’s stated power arrangement and supported control settings for the connected devices. Choose sufficient recording headroom or a comfortable listening level, checking the source and destination rather than treating a connector shape as proof of every function.
Check the Session Before Recording or Listening
Confirm the selected device, input route and output level before a longer session. Make a short test after changing the source, cable or recording mode, and use the exact model’s supported software and power arrangement where required.
Complete Your Workspace
Explore audio interfaces and mixers, headphones for your setup. Suggested products are sold separately. Match the actual input, output, cable wiring and power requirements across the recording or listening chain. This DAC provides RCA line output and needs a separate headphone amplifier for the suggested headphones. Atom Amp 2 accepts the analogue RCA signal; the headphone choices do not plug directly into the DAC. Compare each alternative’s format, ports, gain, included accessories and physical arrangement before choosing.
Frequently Asked Questions
Which signal path and version should I plan for?
Atom DAC+ uses USB Type-B or optical input and RCA line output. Headphones require a separate amplifier. Use its specified external 15 VAC supply rather than treating it as a 5 V USB-powered device.
Can it drive passive loudspeakers directly?
Use a suitable headphone output for headphones, or a line/preamp output into compatible powered speakers or a separate amplifier. RCA line connections do not provide a passive-speaker power amplifier.
What should I check for headphone cables?
Match the actual headphone output socket, wiring and cable. A plug adapter does not convert a single-ended headphone into a balanced connection; Atom Amp 2’s 4.4 mm socket remains single-ended.
Does the highest format apply to every input?
Use the format supported by the selected input, source, driver and application. USB, optical and coaxial paths may have different limits; an advertised maximum is not the format of every recording or music file.
