Autoscan simplifies frequency coordination across 1440 selectable frequencies within a 36 MHz switching bandwidth. The HDX compander system delivers a signal-to-noise ratio exceeding 115 dB, with a frequency response of 40 Hz to 18 kHz. XLR outputs are transformer-balanced and adjustable from -22 to +18 dBu in 2 dB steps. Pilot tone squelch is defeatable for backwards compatibility with earlier EW systems. The metal construction and universal 90-264 V AC power supply make the EM 550 G2 a durable choice for touring and fixed installations alike.
Sennheiser EM 550 G2 — buyer FAQs
What is the Sennheiser EM 550 G2 and what does it do?
The Sennheiser EM 550 G2 is a twin wireless receiver that fits two complete true diversity receivers into a single 19-inch rack housing, giving operators a dual-channel wireless system in one rack unit. It uses Autoscan for frequency selection across 1440 switchable frequencies within a 36 MHz bandwidth, and its HDX compander system achieves a signal-to-noise ratio exceeding 115 dB.
Who makes the EM 550 G2 and where does it fit in the Sennheiser wireless range?
Sennheiser is a German audio company recognised in professional live events for its microphones and wireless systems, covering handheld, lavalier and in-ear monitoring applications across touring, broadcast and installed sound. The EM 550 G2 sits in the 500 series of the G2 wireless generation, positioned as a dual-channel rack receiver with features such as XLR outputs and external charging contacts that distinguish it from the 100 series.
What frequency bands and output options does the EM 550 G2 support?
The EM 550 G2 is available across several frequency ranges including 518-554, 626-662, 740-776, 786-822 and 830-866 MHz, with 1440 switchable frequencies across a 36 MHz bandwidth. XLR outputs are transformer-balanced and adjustable between -22 and +18 dBu in 2 dB steps, and the unit runs on a universal 90-264 V AC power supply, making it suitable for use in different countries.
Is the Sennheiser EM 550 G2 compatible with older EW wireless transmitters?
The EM 550 G2 includes a defeatable pilot tone squelch specifically to allow backwards compatibility with original EW series transmitters. When squelch is disabled, the receiver can work alongside earlier-generation EW system bodypacks and handhelds, which is useful in environments where operators are gradually upgrading a mixed wireless rig.
What should I check when buying a used EM 550 G2?
Confirm the unit's frequency band matches your region's licensed spectrum before purchasing, as the EM 550 G2 is manufactured in several distinct frequency ranges. Check that both diversity receiver channels are functional, that XLR outputs are clean, and that Autoscan operates correctly across the 36 MHz bandwidth.
