Wireless microphones
Shure SLXD vs Sennheiser EW-D
Quick answer
Choose EW-D at $699.00 if volunteers set the system up, because it has no transmitter gain control to get wrong and covers a 56 MHz tuning range. Choose SLXD at $769.00 for channel density, rack space and the Shure capsule ecosystem.

Sennheiser Pro Audio EW-D 835-S Wireless Handheld Microphone System, R1-R6
$699.00 Specs and sizingA 56 MHz tuning range, 134 dB of input dynamic range and no compander at all, so there is no gain knob for a volunteer to set incorrectly.
Best for: A system nobody has time to teach: it is very hard to set up badly
Check price on AmazonBoth are excellent digital systems and both will outlive the console you buy this year. The decision is who operates them. The EW-D is designed so that a person who has never touched a wireless system cannot ruin the signal, because there is no sensitivity control on the transmitter and 134 dB of input dynamic range behind the capsule. The SLXD is designed to fit as many channels as physically possible into shrinking spectrum and into a small rack.
The prices are close enough to ignore: $699.00 against $769.00. Pick on capability. If you are still deciding whether digital is worth it at all, read analog against digital wireless first.

The differences that change a Sunday morning
Both transmit clean digital audio. These are the places where the two designs diverge in a way a church will notice.
The EW-D covers a 56 MHz tuning range with no transmitter gain control at all, while the SLXD packs two channels into one rack unit and shares capsules with the whole Shure range.
| Property | Shure SLXD | Sennheiser EW-D | Who cares |
|---|---|---|---|
| Tuning range | Set by band, narrower | 56 MHz | Churches in crowded spectrum |
| Transmitter gain | Set on the transmitter | None to set, 134 dB input range | Any volunteer-run church |
| Compander | None, it is digital | None, it is digital | Nobody, both are clean |
| Battery life | Up to 8 hours rechargeable | Up to 12 hours rechargeable | Long conference days |
| Range | 330 ft published | Comparable UHF range | Large rooms, either is fine |
| Rack density | Two channels per rack unit on the dual | One channel per half rack | Eight channels and up |
| Capsule ecosystem | Shares with the whole Shure range | Sennheiser capsules only | Changing a capsule later |
| Price | $769.00 | $699.00 | Marginal either way |
Both figures are the manufacturers published specifications. Range in a real sanctuary depends far more on antenna position than on the badge, and both benefit from getting the receiver antennas out of a metal rack.
Choose EW-D when volunteers set it up and take it down
The absence of a transmitter gain control is not a missing feature, it is the design. With 134 dB of input dynamic range the capsule simply cannot overload the transmitter, so the classic church failure of a quiet, hissy channel because somebody turned sensitivity down, or a distorted one because somebody turned it up, is removed rather than mitigated. On a rota that changes every week, that is worth more than any specification on the box.
The 56 MHz tuning range is the second reason, and it compounds with the first. A wide range plus an app that scans and assigns frequencies means a volunteer with a phone can produce a defensible frequency plan in a few minutes. Our coordination guide explains what the app is doing so that somebody at the church understands it.
The 12 hour battery matters for churches with a long day: two services, a rehearsal and an afternoon event will exhaust an 8 hour pack. What you give up is the Shure capsule ecosystem and the dense rack options, and if you already own Shure bodypacks none of them will work here.
Choose SLXD for channel density and an existing Shure system
If the church already runs BLX systems and owns Shure capsules, SLXD is the natural growth path, and the dual SLXD24D at $1,649.00 puts two channels in one rack unit with the receivers coordinating their own frequencies. A ten channel system in five rack units is achievable; the same ten channels in half-rack boxes is a mess of power supplies. Size it on the rack space calculator.
SLXD also keeps the SM58 in the singer's hand, which is not a small thing in a church with a guest musician rota. Everyone knows how to hold it, how far off axis they can get away with, and that dropping it will probably not kill it.
Accept the rechargeable routine honestly. Eight hours on the SB903 pack is enough for a normal Sunday and not enough for a conference day, and somebody has to dock the transmitters every week. Build that into the Sunday checklist rather than hoping.

Frequently asked questions
Does either of these have noticeable latency?
Both add a few milliseconds, which is inaudible through loudspeakers and irrelevant to a congregation. It becomes worth thinking about only when a singer is on in-ear monitors and hearing their own voice through the wireless path, where several milliseconds of delay can feel odd. Even then it is far smaller than the delay of standing ten feet from a wedge.
Can I use my existing Shure capsules on an EW-D transmitter?
No. Handheld capsule threads and bodypack connectors are not interchangeable between the two manufacturers, and there is no adapter worth using. If your church owns several Shure capsules and bodypack microphones, that inventory is a real argument for staying with Shure regardless of what the comparison says on paper.
Which fits more channels in the same spectrum?
Both are far more efficient than analog, and the honest answer is that it depends on the band and the mode rather than the badge. Shure publishes channel counts per band for SLXD, and Sennheiser publishes them for EW-D. Run your address through the wireless channel calculator, then check the manufacturer figure for the specific band letter you can buy.
Are the rechargeable batteries a problem in a volunteer church?
They are a routine, not a problem, and the routine has to belong to a named person. Both systems report remaining time in minutes rather than as a vague bar, which is a real improvement on alkaline guesswork. Keep one set of disposable cells in the drawer for the week somebody forgets, because both transmitters accept them.
Is either of these overkill for a 200 seat church?
Yes, if you only need two or three channels. A 200 seat church with a preaching microphone and two vocals is well served by an analog system at roughly half the price. Digital earns its cost when the channel count passes about six, when the local spectrum is crowded, or when rack space has genuinely run out.
