LIMETREE BRIDGE II

The Limetree BRIDGE II is a high-class network adapter or audio renderer which can transfer music digitally in studio master quality from streaming providers and local storage media to existing D/A converters or other devices with digital inputs. This makes it possible to upgrade an existing hi-fi system with streaming for little money. Here we would like to address owners of older LINDEMANN devices such as the 820S or the 825, but of course all other customers with a converter or a CD player with a digital input as well.

For this purpose the Limetree BRIDGE II is simply connected with the network by means of a LAN cable or via WLAN. It has also a USB port for connecting harddisks or USB storage media. There is an optical and a coaxial digital output. A professional studio engineering sample rate converter makes sure that all streamed formats can be played back on an existing converter without major losses in sound quality.

Technology

The circuitry of the Limetree BRIDGE – designed around the powerful streaming platform – has been tuned for optimum signal quality. All music files are post-synchronized by an ultra precise FemtoClock. The data processed in this way are free from “jitter“, the most frequent cause of a poor digital playback quality. When output over the digital outs, the DSD data are automatically converted into high-resolution PCM data so that owners of older DACs can also enjoy high-res media of all kinds. With many older DACs the Limetree BRIDGE’s exceptionally low-jitter digital signal produces an audible increase in sound quality. For the power supply we use a high-quality “medical grade“ wall plug transformer which ensures a particularly good isolation from line disturbances. Owing to the elaborated onboard filtering and special voltage regulators, we were able to realize an exceptionally low-noise power supply with a ripple voltage below 10 µV.

Features

Streaming-Modul

The LINDEMANN streaming platform offers a studio master grade reproduction. Either through a LAN connection or wireless via WLAN. Due to WPS, integrating the device into your existing system is just a breeze. Moreover, the ARM core high-performance processor and the web update feature make the platform absolutely future-proof.

App

The LINDEMANN app is available for Android and iOS, both for smartphones and tablets. It enables to play back content from all major streaming providers, music servers and USB storage media. The album-oriented programming excels by smooth browsing and an easy, intuitive operation.

Bluetooth2

The Limetree BRIDGE II offers a Bluetooth function which enables a wireless music playback e.g. from smartphones or tablets. At the same time the A2DP Bluetooth audio transmission protocol ensures the very best sound quality.

Multiroom

A special highlight is our multi-room function which allows to run several streamers in different rooms separately or coupled. These are conveniently controlled via the LINDEMANN app.

CD_USB_Extern

Via USB the Limetree BRIDGE II supports the docking of external CD-ROM drives (e.g. Apple USB SuperDrive) and turns into a high-end CD player without much effort or cost! The drive is automatically recognized and the CD playback can be controlled by the LINDEMANN app or the IR remote. Thereby the CD data are cached in a memory and then streamed.

USB_2

The Limetree BRIDGE II can play back music from USB storage media such as USB sticks or harddisks. For this purpose the device is equipped with a USB host port on the back.

OutputMode

The digital outputs of the Limetree BRIDGE II can be perfectly adapted to the input of the employed D/A converter. First the maximum permissible sample rate of the connected D/A converter is set. In a second step the audio data from the streaming platform are adjusted by a high-quality sample rate converter from the studio technology to enable a reproduction of all resolutions without any loss of sound quality. For the up- and down-sampling process we use only binary multiples: x1, x2, x4, x8. 192 kHz will thus be converted to 96 kHz or 48 kHz and vice versa, 44.1 kHz will become 88.2 kHz or 176.4 kHz. Two different operating modes (strategies) are up for choice: up-sampling to the highest possible value in each case, or bit-perfect reproduction without up-sampling.
