What kind of runtime can I expect from a full battery charge?

With two LR6 alkaline AA cells, the DPTTetrad runs for 6 hours; using rechargeable HR6 AA NiMH batteries extends runtime to 7 hours. Both battery types are supported without any configuration changes.

Does this transmitter work with standard microphones, or does it require special equipment?

The DPTTetrad accepts any microphone via its 3-pin TQG connector and includes a fully adjustable mic-to-line input with 0 dB to 30 dB gain control, accommodating everything from low-output condensers to high-output instruments without distortion.

Is the audio transmission compressed, and does it support encrypted operation?

No—the DPTTetrad uses 24-bit 48 kHz uncompressed audio coding for studio-quality signal integrity. It also includes 128-bit AES standard encryption to protect your audio signal from interception, making it suitable for confidential sessions and secure installations.

What is the maximum transmission range and will it work in my region?

The DPTTetrad operates on 2.4 GHz license-free technology with 10 mW RF output in Europe and 100 mW in all other regions. Actual range depends on your receiving system and venue acoustics; the unit includes digital diversity and out-of-range warning functions.

How does the DPTTetrad compare to other professional wireless transmitters like the Shure ULXD1 or Sennheiser EW-D SK?

The DPTTetrad competes directly with those models in professional touring and studio environments, offering uncompressed 24-bit transmission, low noise floor, and AES encryption in a compact form factor. Exact feature and workflow differences depend on your receiver system and specific application requirements.

AKG DPTTetrad Digital Pocket Transmitter

The DPTTetrad is a compact, lightweight body-pack transmitter built for gigging musicians and live sound professionals who demand license-free operation and studio-quality audio without compromise. Its pocket-sized form factor—measuring just 92 mm × 64 mm × 22 mm and weighing 70 g—stays out of your way on stage or in the studio while delivering the signal integrity and reliability that keeps your performance clean and interference-free.

Audio Performance & Transmission

24-bit 48kHz uncompressed audio coding ensures your instrument or vocal signal reaches the mixing desk with studio-quality fidelity, while a 120 dB-A signal-to-noise ratio keeps the audio clean and transparent across any stage setup. 128-bit AES standard encryption protects your signal from RF interference and unwanted interception; linear frequency response and fully adjustable mic-to-line input (0 dB to 30 dB gain control, max input 3 Vrms) let you dial in everything from a delicate condenser mic to a hot instrument output without noise or distortion.

Connectivity & Power Management

The transmitter operates on 2.4 GHz license-free technology with 10 mW RF output in Europe and 100 mW outside Europe, connected via a 3-pin TQG connector for rock-solid signal routing through your rig. Battery flexibility—either two LR6 AA alkaline cells (6-hour runtime) or two HR6 AA NiMH rechargeable cells (7-hour runtime)—keeps you playing through long sets or multi-day gigs without forced downtime.
