Digital 6000, the latest member of Sennheiser’s professional wireless microphone range, is shipping now. Incorporating their Long Range transmission mode and proprietary audio codec from Sennheiser’s Digital 9000 series, is aimed at rental companies, theatres, broadcasters and houses of worship that need a flexible two-channel wireless solution that allows the use of existing accessory infrastructures.
The Digital 6000 series comprises a two-channel receiver that is available in two different versions, a bodypack and a handheld transmitter, and a rack-mount 19” charging unit. The receiver’s switching bandwidth of 244 MHz (470 to 714 MHz) is covered by three transmitter versions (470 – 558 MHz, 550 – 638 MHz, and 630 – 718 MHz). Up to eight receiver units can be daisy-chained without the need for an additional antenna splitter; the multi-channel system will work with a single pair of antennas. System latency is 3 milliseconds.
The Digital 6000 features switchable AES 256 encryption, with the transmitters also supporting the proprietary encryption of the Digital 9000 system.
Existing antenna infrastructures can continue to be used as the system works with standard active and passive wideband UHF antennas, with the highly frequency-selective input filters being contained in the EM 6000 receiver.
The Digital 6000 transmitters use the same high-performance rechargeable accupacks as their Digital 9000 counterparts. The SKM 6000 handheld transmitter features Sennheiser’s standard capsule interface – it can therefore be used with any microphone head from the evolution wireless Series, the 2000 Series, and also with the special 9000 Series heads.
The receiver’s operating controls have been modeled on the EM 3732 and a new menu control with white OLED display gives an overview of the RF signal, link quality, audio signal, battery status, frequency, transmitter name and encryption. Several home screens provide access to further information, without the user having to navigate through submenus. Critical operating conditions and error messages are directly indicated on the display.
The series’ L 6000 charging unit is a 19”/1U mainframe device that can be fitted with up to four charging modules as required, each of which recharges two bodypack or two handheld batteries, respectively. Three-colored LEDs on the front panel give a quick overview of the charging process for each battery, while two additional LEDs monitor the device status. More detailed information as well as additional parameters such as battery runtime, charging cycles and remaining capacity can be accessed via the Wireless Systems Manager. The L 6000 charging unit can also be used for Digital 9000.
The EM 6000 receiver is fitted with a digital AES-3 output with wordclock in/out, a transformer-balanced analog XLR-3 outputs and ¼” (6.3 mm) jack outputs. Its Dante counterpart, the EM 6000 Dante offers an additional Amphenol RJ-45 connector for integration into a Dante network.
