Line Magnetic LM-32DAC
Line Magnetic LM-32DAC
Digital to Analogue Converter
The LM-32DAC digital to analogue converter offers the flexibility to select either tube or solid state output on the fly, allowing you to enjoy the output that best matches your system or music selection.
This DAC takes Xmos USB audio technology which utilises high speed USB 2.0 receiving and decoding 32bit/192kHz high resolution digital signals and is designed with top grade ESS 9028Pro DAC chips.
It is an asynchronous design with awesome performance from its low distortion, ultra-low-jitter clock recovery technology and features five digital inputs: AES/EBU, BNC, USB, optical and coaxial that will lock onto any signal input at 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, 192KHz, 352.8KHz, 384KHz, DSD64, DSD128 and DSD256, displaying the input frequency used on the front LCD panel.
The LM-32DAC features separate high quality power supplies for the Analogue and Digital sections, a toroid power transformer for Digital and a EI power transformer for Analogue. It also has separate rectification, using high speed circuitry for the Digital section and a 6Z4 tube for the Analogue section.
Finally, the LM-32DAC incorporates Line Magnetic Audio’s world class leading Tube analogue output stage, utilising two 12AU7’s in the buffer for a true tube output.
– Separate power supplies for analogue and digital sections
– Selection of tube or solid state output on the fly
– Multiple inputs with wide range of input frequencies accepted
– High quality components
