Unleash true high fidelity sound with the Mass Fidelity Relay; more than a Bluetooth receiver, it is also a DAC that converts digital ones and zeros into sound you can hear.
Ultra Fidelity Bluetooth DAC
Inside Relay is a legendary Burr-Brown 5102, a costly DAC usually found only in top shelf audiophile home audio and home theatre systems. Relay’s Cirrus microprocessor decodes aptX, a superior performance digital audio codec used in later-generation smart devices (particularly Android OS). This combination of advanced hardware and firmware preserves all the musical detail, dynamic range and full bandwidth response that elevate digital music from a mere collection of notes up to emotion-packed artistic expression.
With the vast array of wireless audio options such as Airplay, Sonos, Roku and countless others, why did we choose Bluetooth especially when Bluetooth has a reputation for poor sound quality and limited operating range? Every modern smartphone, wireless device and laptop is Bluetooth equipped so it affords instant compatibility for millions of people. There is no need to own or be within range of a wireless router. There’s no need to synchronise playlists and accounts between devices. There is no need to download an App to make it work; in fact it only takes 1 minute to set up and start playing music. Bluetooth is a familiar technology to millions of people so it is not intimidating and difficult to set up, as are the router-dependant systems. The surging popularity of portable Bluetooth speakers attests to the public’s enthusiasm for the technology’s convenience.
Long Range Wireless
Limited range and signal dropouts have traditionally plagued wireless audio systems. The Relay employs the latest technologies and superior components such as an ultra low-loss connector and external high gain antenna to ensure consistent, glitch-free performance for 10 meters (30 feet) or much more.
Noise Free Sound
You want to be able to enjoy great sounding music and run the microwave, don’t you? Low quality wireless audio speakers and systems are prone to picking up noise generated by home appliances, other wireless devices and fluorescent lights. Relay’s linear low noise, low-dropout regulators and superior input noise filters reject signal noise and interference from the outside world while its Triple Star Ground circuit geometry eliminates any possibility of ground loop induced hum.
More Precise Clock
'Jitter' is a form of distortion that relates to a digital system’s 'clocking.' It’s bad and you don’t want any of it in your audio path. Relay’s ultra stable phase locked audio sample clock vastly reduces jitter allowing the DAC to render the audio signal more faithfully. Just one more reason why Relay sounds distortion free and utterly faithful to the music the artist intended you to hear.
Choose your DAC
Do you have an outboard DAC in your system that you love? No problem; thanks to its unique Uni-fi output stage you have the option of using your outboard DAC with Relay. With a 5 second push of the power button Relay switches the two RCA jacks to output 24 bit S/PDIF digital (Only one output required per DAC. Yes, you can feed a digital stream to two separate outboard DACs). Either with its built-in DAC or an outboard DAC you’ll get the very best possible wireless Bluetooth sound quality.
Unlimited Music & Control
Relay doesn’t require any apps or software in order to give you full control! Within minutes you’ll be able to choose and control any digital music source accessible from your smart device. With Relay and a smart device your home audio or home theatre system will have full access to a virtually unlimited universe of music via streaming services like Spotify and Pandora plus thousands of online radio stations and podcasts. You can also access any music library, whether cloud-based or on a wireless home network.
Pairing a smart device to the Relay is a snap. Push the control button on the back of the unit briefly; the pilot LED will glow white. The Relay automatically goes into pairing mode and initiates the software that synchronises the Relay and the Bluetooth device. Make sure Bluetooth is activated in you smart device, select “Relay” from the list of available devices and ta da, you’re ready to rock. In households where more than one person uses the system or when guests want to share their music through the Relay and the hi-fi system, PartyPairing and TurboPairing come into play.
PartyPairing eliminates a step in switching from one source device to another. Just turn Bluetooth off in the first device, turn Bluetooth on in the second and select Relay as the device. There is no need to reset the Relay and press it’s control button a second time. The Relay can connect to only one smart device at a time; however it is capable of remembering up to six devices. Once a device has paired with the relay, TurboPairing remembers it to speed up pairing at a later time. Once more than six devices have been paired the oldest device is discarded. To add a device back into TurboPairing memory, simply reconnect the device.
Relay looks totally at home sitting next to even the costliest and most attractive home audio components. Its enclosure is hewn from a solid block of aerospace grade aluminium, the result of an elaborate manufacturing process beginning with the use of premium raw materials at the smelter and ending with precision milling of the surface treatments. Even though it’s small enough to hide away you’ll want to display it proudly out in the open. There’s nothing wrong with showing off your cool stuff.
Relay has two gold-plated RCA jacks that can operate either as analogue or digital outputs. Simply connect the supplied RCA-RCA signal cable from Relay’s L&R outputs to the RCA analogue inputs of any audio system. For systems that have 3.5mm “mini” jack input, use the supplied RCA-mini cable. Listeners who prefer to use an outboard DAC or the digital input of a surround receiver can do so by holding the rear-panel control button for 5 seconds until the pilot light turns orange. Connect either output jack to the digital input of the amp, receiver or DAC. Relay can feed two digital streams at the same time. For example you can feed one digital output to a surround receiver or your system’s primary DAC and the other to a headphone amp/DAC combo unit.
Ten Ways to Enjoy
