The HTDZ HT-81A captures unidirectional audio using an electret condenser capsule across a 100Hz to 20kHz frequency range. With a 360mm aluminum body, it targets sound sources while rejecting side-axis noise. This updated model adds 48V phantom power support and extends high-frequency response by 4kHz. Balanced output replaces the old unbalanced signal to reduce electrical noise.
Key Features
- Dual Power Supply: 48V Phantom and 1.5V AA battery support. Operates during local load shedding when external power fails.
- Switchable Pickup: Normal and Tele switchable directional pickup pattern modes. Focuses on distant subjects while ignoring background noise.
- Aluminum Build: 360mm length aluminum frame weighing a total 120 grams. Resists physical impact without straining camera hot shoes.
- Audio Range: 100Hz to 20kHz response with 75 Ohm impedance. Captures high-pitched detail while filtering low-end hum.
- XLR Connectivity: Balanced 3-pin XLR connector with 8-meter cable. Transmits clean signals over long distances to mixers.
- Brand Warranty: 12-month coverage for manufacturing defects. Protects the investment against internal hardware failure.
Frequently Asked Questions
Does HTDZ HT-81A need phantom power?
No, it runs on a 1.5V AA battery if 48V phantom power is unavailable. The dual-power circuit detects the source automatically for uninterrupted recording.
What is the frequency response?
The microphone captures audio between 100Hz and 20kHz. This range filters low-end rumble while maintaining high-frequency clarity for speech.
