Spohr is also highly impressed by the stability of the reception, which for him is one of the many convincing features of the new EW-DX systems: “Even in critical RF environments, there are no problems at all with interference or audible dropouts. Sennheiser shotgun microphones at the front edge of the stage pick up the audience’s reactions to the exciting stage show. An A 5000-CP passive antenna with circular polarisation connected to an AC 3000 Active Transmitter Combiner completely covers the large performance area of the stage. For the tour, an additional channel was hired for the percussionist. The systems used are EK 2000 IEM, which communicate in the AW+ band (470 – 558 MHz) with four SR 2000 IEM units. A switching bandwidth of up to 88 MHz enables the transmission of up to 146 channels in standard mode and up to 293 channels in Link Density mode.įor many years now, Culcha Candela have been using in-ear systems from Sennheiser’s 2000 series, and even though they have been in operation in countless concerts, they still do their job perfectly. In EW-DX systems, the innovative “Sennheiser Performance Audio Codec” (SePac) ensures excellent audio transparency from the capsule input to the system output. Latency, which is always a factor in digital systems, is a mere 1.9 milliseconds, making it imperceptible in practical application. The special features of the new Sennheiser EW-DX series include “Intelligent Switching Diversity”, which enables antennas to be switched between audio frames – a process that guarantees stable transmission without audible artefacts. Two Sennheiser EW-D ASA splitters – cascaded to produce an eight-channel splitter – are connected to ADP-UHF passive directional antennas (470 – 1050 MHz), so that eight channels can be received via the two antennas. Their analogue outputs are connected with an audio splitter to ensure the FOH and monitoring consoles are able to access the microphone signals independently of one another. Culcha Candela’s equipment includes five space-saving 9.5” EW-DX EM two-channel UHF receivers in the R1-9 frequency range (520 - 608 MHz).
