Frequently asked questions
What is the key functional difference between these two products?
The SR470 BD8 is a stationary receiver that sits in a rack and receives wireless signals from transmitters. The DPTTetrad is a portable transmitter worn on the body that sends audio wirelessly to a receiver. They perform opposite roles in a wireless system.
Can I use both products together?
Not directly as described. The SR470 BD8 operates on Band 8 (570.1–600.5 MHz), while the DPTTetrad operates on 2.4 GHz license-free technology. They use different frequency bands and are not compatible with each other.
Which is better for a mobile performer versus a fixed venue?
The DPTTetrad suits mobile performers and presenters because it is lightweight and worn on the body. The SR470 BD8 suits fixed venues and theaters because it is a stationary rack-mount receiver designed to stay in one location.
What audio quality can I expect from each?
Both deliver a 120 dB-A signal-to-noise ratio. The SR470 achieves transparency through low distortion (below 0.3% THD) across 35–20,000 Hz. The DPTTetrad delivers studio-quality transmission via 24-bit 48kHz uncompressed audio coding, which preserves fidelity without lossy compression.
