Bluetooth Receiver: Mass Fidelity's Relay Bluetooth receiver supports
Bluetooth version 2.1+EDR and lets you stream music wirelessly from almost any
Bluetooth enabled device; such as a Apple iPod/iPhone/iPad, Android
smartphone/tablet, Blackberry, Windows PC, Mac computer, and more to your home
audio system with a free analog RCA or digital coax input. Relay is a true high
fidelity component that brings out the full sound quality potential from your
wireless digital music.
Note: With Relay you'll never miss a call even if you're using your phone
to listen to music. Incoming calls and notifications take precedence over audio
playback. If the phone rings, Relay gently mutes the music volume and allows the
call to be answered from the phone.
Wireless Audio Streaming: The Relay Bluetooth receiver
supports Bluetooth A2DP and lets your stream stored music libraries, music apps,
internet radio, podcasts, and Cloud servers from your Bluetooth-enabled
smartphone/tablet, computer/laptop, or other Bluetooth-compatible device to your
home audio system. Bluetooth's A2DP-profile can consistently sustain 1.5Mbps and
allow bursts of up to 3Mbps; more than enough data to stream uncompressed
Note: To access audio files on a home network with iOS devices enable
"Home Sharing" on the mobile device and every music file on your home
network is instantly available to playback on the Relay. For Android devices
use a 3rd party music player app (such as BS Player) to access networked
aptX & AAC Decoders: The Relay Bluetooth receiver
decodes both aptX (for Android) and AAC (for Apple) encoded signals for
External High-Gain Antenna: 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 up to 30'.
24-Bit DAC & Audio Processor: The Mass Fidelity Relay is more than
just a Bluetooth receiver; it's also a Digital-to-Analog Converter (DAC) and
digital audio processor. Inside the Mass Fidelity Relay is a Burr-Brown 24-bit/48kHz
DAC (5102) and a 24-bit Cirrus Logic digital audio processor. This combination
of advanced hardware and software preserves all the musical detail, dynamic
range and full bandwidth response that will elevate your wireless digital music
experience with a frequency response of 10Hz to 20kHz (+/-0.2dB), 112dB
signal-to-noise ratio, and 112db dynamic range.
Low Jitter: Relay's ultra stable phase locked audio sample clock vastly reduces jitter
allowing the built-in 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.
Triple Star Ground Circuitry: 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
Simple Pairing: Pairing a Bluetooth device to the Relay is a snap;
simply push the control button on the back of the unit briefly and see the
rear-panel LED glow white. The Relay then automatically goes into pairing mode
and initiates the software that synchronizes the Relay and your
Bluetooth-enabled device. Make sure "Bluetooth" is activated in your device, and
then select "Relay" from the list of available devices. The Relay can connect to
only one smart device at a time; however it is capable of remembering up to six
devices. In households where more than one person uses the system or when guests
want to share their music through the Relay and your hi-fi system, the Relay
offers TurboPairing and PartyPairing.
- TurboPairing: 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.
- PartyPairing: 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.
Note: Due to the differences in Bluetooth technology, some
Bluetooth enabled devices may be incompatible, function improperly, or may not
support all features when used with the Mass Fidelity Relay.
Analog & Digital Outputs: The Mass Fidelity Relay has
two gold-plated RCA jacks that can operate either as analog or digital outputs.
- Analog Output: Simply connect the supplied RCA-to-RCA signal
cable from Relay's L&R outputs to the RCA analog inputs of your audio
system. For systems that have minijack (3.5mm) input, use the supplied
- Digital Output: 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 LED turns orange. Connect either
output jack to the digital input of the amp, receiver or DAC (digital coax
cable sold separately). 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.
Aluminum Chassis: The Mass Fidelity Relay's chassis is machined from
solid aerospace-grade aluminum for a rigid, non-resonant chassis.
External AC Power Supply: The Relay operates off of standard household
current using the supplied external AC power supply.
- Input: 100-240V~50/60Hz, 0.2A
- Output: 5V - 1.0A
