Frequently asked questions
What's the main functional difference between these two products?
The SR470 BD8 is a stationary receiver that sits in a rack and can coordinate up to 48 wireless channels for a venue or theater; the DPTTetrad is a portable body-pack transmitter for individual users. You cannot use one without the other—they serve different roles in a complete wireless system.
Can I use the DPTTetrad with the SR470 BD8?
The product descriptions provided do not specify whether these two units are compatible or operate on the same frequency bands. You should verify compatibility with the manufacturer or retailer before purchasing.
Which is better for a small live performance—a solo musician or presenter?
The DPTTetrad is the right choice for individual performers and presenters because it is a portable body-pack transmitter designed for that use case. The SR470 BD8 is a receiver only and requires a compatible transmitter to function.

Both deliver 120 dB(A) signal-to-noise ratio. The SR470 BD8 achieves sub-0.3% THD and 35–20,000 Hz bandwidth; the DPTTetrad uses 24-bit 48 kHz uncompressed audio with linear frequency response and AES encryption.
