Prism Sound

The Prism Sound Lyra 2 is a USB audio interface designed to deliver reliable precision and high-resolution audio I/O for musicians, vocalists, songwriters, and audio engineers in home, project, and mobile studios. Its stable clock allows operation at up to 24-bit / 192 kHz resolution with high jitter rejection. With latency as low as 0.08 ms, it is well suited for recording, overdubbing, and even send-and-return routing.Line, instrument, or microphone sources can be connected via the stereo 1/4" TRS inputs, two 1/4" instrument inputs, and two XLR 3-pin inputs. Phantom power is selectable as are the input pads and built-in limiters. The four 1/4" line outputs are ideal for connecting to speakers and power amps, while the front-panel 1/4" jack offers dedicated level and mix controls for independent headphone monitoring. Additionally, digital connectivity includes RCA coaxial for S/PDIF or AES3, TOSLINK optical for S/PDIF or ADAT, and BNC for word clock. An RJ45 port is present for future AVB integration.The Lyra 2 is compatible with Mac OS X and Windows systems via its class-compliant USB 2.0 connectivity. An IEC power cable, USB cable, and XLR to RCA adapters are included. Signal Path Analog and digital input channels are available as inputs for your audio workstation software through the host computer's audio driver. Similarly, analog and digital outputs, and stereo headphone outputs can be played independently. For low-latency monitoring to headphone or main outputs, each output pair can optionally be driven from the built-in DSP mixer with an individual local mix of any selection of inputs through the controller applet. All analog inputs are electronically balanced with automatic unbalanced operation. Analog outputs are electronically balanced with bootstrapping (level is maintained if one leg is grounded).Verifile Technology Verifile is a radical new proprietary technology exclusive to Prism Sound, which allows computer audio streams and recorded files to be quickly checked for a wide range of clicks, errors, and dropouts, without any compromise in the audio content or any additional metadata. Verifile is a fragile steganographic process, which embeds derivative data within the dither of the ADC, containing a rolling hash code which allows the audio data to be thoroughly and continuously checked. Recovery of this data from the audio stream or file enables verification that the stream or file contains exactly the audio data that was produced by the ADC at the time of recording. Any incorrect samples, missing or repeated audio segments or any other audio errors in the resulting files can be reliably detected, providing complete confidence that the recorded file is error-free. Processing such as EQ, level changes, additional redithering, or sample-rate conversion done to a Verifile recording will result in a failure to decode the rolling hash code in the dither and hence indicate that the recording is not an original.Reliable Quality Prism Sound uses precise software calibration techniques in its converters to avoid the unreliability of pots and tweaks. Minimizing noise, interference, and hum was a priority in the design. All the analog circuits have galvanic isolation, while the unit's electronically balanced I/O allows it to handle common mode interference sources and trouble-free connection to unbalanced equipment.USB 2.0 Compatibility The Lyra 2 is easy to connect to your computer and to your outboard gear. For both Mac and Windows platforms, there is a controller application to configure the unit and control its built-in mixer and various functions. Aside from the monitor and headphone level controls, everything else is operated solely from the Lyra controller application. The controller software opens on-screen as a separate panel alongside your existing editing software. Since the Lyra 2 is UAC2 compliant, it will also work with recent Linux and Android builds, although no control panel is provided.Flexible I/O Uti
