Product Detail

The perfect sound

Stream music wirelessly from your smartphone to any sound system in true high fidelity.

Bridging Hi-Fi and digital

The Relay Hi-Fi wireless receiver connects all your Bluetooth® smart devices to your existing stereo setup so you can sit back and use your device as the controller. Enjoy all your digital music on your favorite sound system whether it's stored on your device or streaming from the cloud without having to switch sources.

Welcome to the party!

The Relay is enriched with Mass Fidelity's wireless Party Pairing™ technology bringing the social element back to Hi-Fi by allowing everyone at the party to take turns being the DJ! It's a global jukebox only limited by the amount of music you and your friends can tap into from both stored music files or streaming services.

The perfect sound

The Relay's output stage is accessible via gold plated RCA phono style connectors. The Relay uses a professional grade Burr Brown 24 bit Digital to Analog Converter to deliver a solid 2 Volts RMS output power to your analog Hi-Fi system.

Grounding Scheme

The Relay uses 3 separate ground domains; one for digital signals, one for analog signals, and one for radio frequency signals. Each is designed to be as 'solid' as possible. A bulk decoupling capacitor is used to remove any potential ground loops. Grid-viaing between ground layers in each ground domain, and star grounding of the three domains ensure excellent ground integrity.

Internal low-noise power supply

Linear low noise, Low-dropout Regulators and common mode input noise filtering on power supply have been implemented to improve rejection of unwanted signal noise and interference from the outside world.

System Clocking

A slew rate limited clock source is utilized to improve rejection of unwanted transient noise that would otherwise distort the audio signal thereby lowering the systems overall noise floor. An ultra stable phase locked audio sample clock is used to reduce jitter allowing the DAC render the audio signal more faithfully.

Analog output

The Relay's output stage uses a professional grade Burr Brown Digital to Analog Converter which has the following characteristics:

• 24 bit Digital to Analog conversion
• Signal to noise ratio: 112dB
• Dynamic Range: 112dB
• Total harmonic distortion: -93dB
• Interpolation filter stop band gain: -60dB
• Pass band flatness: +/-0.02dB
• DC coupled output stage
• 2Vrms power output

Wireless Performance

The Relay combines an ultra low loss SMA connector for increased range and signal stability with an external antenna for increased standing wave ratio efficiency.

High efficiency antenna characteristics:

• 80% average efficiency
• Maximum VSWR 1.6:1
• Peak gain 2.2dBi

Enclosure

The Relay's enclosure is hewn from solid aerospace grade aluminum billet, it is the result of an elaborate manufacturing process beginning from raw materials at the smelter and ending with precision machinery executing the final surface treatments resulting in a housing for the electronics that is both functional and beautiful.

Set-up

Simply plug the Relay into the AUX analog input of your existing hi-fi system and push power! No wi¬-fi network required. No platform specific software driver downloads or hardware configuration required. No pairing button or pairing codes. Scan for the device and connect!

Control

Say goodbye to app downloads! By taking advantage of modern wireless streaming protocols the Relay doesn ' t require any external software to be added to your device in order to give you full control of the Relay!

Volume

When connected to the Relay, it ' s best to turn the volume on your smart device fully up and then use the volume control on your hi-fi stereo system.

To guarantee the best sound experience:

1. Pair your smart device to the Relay.
2. Play some music from your device to ensure the hi-fi stereo system is working, and then stop the music.
3. Turn the volume on your stereo down to the lowest volume setting.
4. Turn the volume on your smart device to the highest setting.
5. Play the music again and slowly increase the volume on your stereo until you've reached the maximum desired listening volume.

Now you can use your smart device to control both content selection and system volume!

Bing!

Incoming calls and notifications take precedence over audio playback. To avoid such party interruptions, turn off the sound notification on your smart device.
