Operating Instructions

1. 32-Bit Float Recording

The BooMax system supports 48kHz/32-bit float recording, providing an ultra-high dynamic range and distortion-free sound. This feature minimizes the risk of audio clipping and offers greater flexibility during post-production.

2. Internal Storage and Backup

Each transmitter includes 32GB of internal memory, capable of storing up to 40 hours of uncompressed 24-bit audio or 32-bit float backup. This allows for standalone recording or serves as a crucial backup in case of wireless signal interruption.

3. Dual Internal Microphones with Pickup Patterns

Each transmitter features dual internal mic capsules, allowing you to switch between cardioid and omnidirectional pickup patterns. This adaptability is useful for various recording scenarios.

• Cardioid: Focuses on sound directly in front of the microphone, reducing side and rear noise. Ideal for interviews or solo speaking.
• Omnidirectional: Captures sound from all directions, suitable for group discussions or ambient sound.

4. IPS Touchscreen and Precision Dial

The receiver features a 1.08-inch IPS touchscreen and an intuitive control dial for easy adjustment of settings. You can monitor volume, battery status, audio modes, and more directly from the screen.

5. App Control (Comica Audio App)

Connect the BooMax system to the Comica Audio app via Bluetooth for remote control and monitoring. The app allows you to adjust gain, tweak settings, and monitor recording status from your smartphone.

6. CalMix Dual-Stage Noise Reduction

The exclusive CalMix technology provides advanced two-stage noise cancellation, effectively reducing background noise in various environments. This feature can be activated directly on the microphone or via the receiver.

7. Real-Time Monitoring

Monitor your audio in real-time using the 3.5mm headphone jack on the receiver. This allows you to ensure optimal audio levels and quality during recording.

8. Output Modes (Mono, Stereo, Safety Track)

The BooMax system offers flexible output modes to suit your recording needs:

• Mono: Combines both transmitter audio channels into a single mono track.
• Stereo: Separates the audio from each transmitter into distinct left and right channels.
• Safety Track: Records a secondary track at a lower gain level (-6dB) as a backup against unexpected audio peaks.

9. EQ Settings

Adjust the audio equalization (EQ) settings directly from the receiver's touchscreen to optimize sound for different environments or vocal characteristics. Options typically include Low Cut, High Fidelity, and High Frequency Boost.
