The SL DI 4XLR is a Dante interface developed for use with Sennheiser SpeechLine receivers that can be powered and also allows to power a Dante network from the four analog MIC/LINE inputs.

Sennheiser SL DI 4 XLRMagnetron has announced the SL DI 4XLR digital analog audio converter from Sennheiser. A Dante interface with four symmetrical MIC/Line inputs and HF filter, which have been designed as XLR 3F sockets.

For each input it is possible to activate gain settings, through software, of 0dB, +15Db,+30dB and +45dB a 10dB pad as well as a 48V Phantom power. The status LEDs located on the front panel of the unit indicate the corresponding gain and pad settings as well as the Phantom energy level for each of the four inputs.

The unit incorporates two RJ-45 network sockets that allow the mounting of Dante series wiring (Dante Daisy Chain). Internal A/D conversion is performed at a resolution of 24 bits and a sampling rate of 48 khz. The transmission speed is 100 MB/sg.

Sennheiser SL DI 4 XLRThe transmission range of the unit is between 20Hz and 20,000Hz. The input impedance is >1,8 kiloohms for any gain adjustment. The equivalent proper noise is -113 dBu. Maximum input levels (no 10dB pad) are +8 dBu with gain of 0 Db, -7 dBu with gain of +15 Db, -22 dBu with gain of +30 dB and -36 dBu with +45dB gain. With connected pad, maximum input levels increase by 10dB.

The harmonic distortion of the system plus noise is < 0.02% with any gain adjustment (3dB input signal below maximum level).

The unit can receive power via CAT5 Ethernet cable, using a PoE network switch that supports 802.3 af or via an external 12V DC power supply.

In case of power supply via PoE, loop connection of up to two units is possible, and in case of power supply through an external power supply of 12 V DC, up to three units. Power consumption is 2.7 W (225 ma) to + 12 DC V without Phantom power and 5,5 W (460ma) to +12 V DC and a current of 10 mA per input with connected phantom power.

The unit features a robust metal housing with integrated mounting angles. The dimensions of the housing are 219 X 38 X 120 Mm (W x H x Pro) and the weight is 0,77 Kg. The service temperature is between 0ºC and 40ºC
