Android 14 · 100W DSP Audio · XLR +48V Phantom Power · 5-Band Equalizer

📖Product Overview

The Qtenboard QM-4333JT-AUD is a specialized audio-enhanced variant engineered for teaching environments where sound quality is paramount. Built around a 43-inch front display and 22-inch capacitive touchscreen running Android 14, this model features a professional-grade 100W RMS audio system with dual 50-watt studio monitor-grade speakers, a DSP 5-band equalizer with six preset acoustic modes, and a balanced XLR microphone input with +48V phantom power for professional condenser microphones. Whether for music appreciation, language labs requiring pristine vocal clarity, or large lecture halls where every word must be heard, the QM-4333JT-AUD delivers an uncompromising audio experience.

⭐Key Features

📊

100W Studio Monitor Speakers

Dual 50W RMS speakers with 45Hz–20kHz frequency response reproduce the full audible spectrum. 100W total output ensures uniform coverage for spaces seating 80–150 people without external amplification.

🔌

DSP 5-Band Equalizer

Parametric equalization with 6 one-touch presets: Lecture (vocal clarity), Music (flat response), Movie, Voice (compression), and two Custom user-defined modes.

🖥️

XLR +48V Phantom Power

Professional balanced XLR input with switchable phantom power supports studio-grade condenser microphones for broadcast-quality voice reproduction.

🎯

aptX HD Bluetooth 5.2

High-resolution wireless audio streaming with Qualcomm aptX HD codec (24-bit/48kHz) from compatible devices for music and audio learning materials.

📡

RCA Line Output

Dedicated line-level output enables connection to external recording devices, assisted listening systems, or supplementary powered speakers.

🛡️

Acoustic Damping Interior

Internal cavity features acoustic damping material to minimize enclosure resonance, ensuring clean, uncolored sound reproduction even at high volumes.

🏆Project Case Studies

Conservatory of Music — Eastern Europe

A national music conservatory equipped 18 practice rooms and 3 lecture halls with QM-4333JT-AUD podiums. The aptX HD Bluetooth streaming allowed instructors to wirelessly play reference recordings in CD quality, while the DSP presets enabled instant switching between lecture mode for music theory classes and flat-response mode for critical listening sessions.

University Language Department — North America

A university linguistics department deployed QM-4333JT-AUD in their phonetics and language acquisition labs. The XLR condenser microphone input captured the subtle vocal nuances essential for phoneme demonstration, while the 100W system ensured every student could hear the distinctions clearly in rooms designed for 60 students.

💬Frequently Asked Questions

❓Is an external amplifier required for large rooms?

No. The built-in 100W RMS system is designed to cover rooms of 80–150 seats without external amplification. For venues exceeding 150 seats or with challenging acoustics, the RCA line output can feed an external PA system while still using the podium's DSP processing and microphone inputs.

❓What type of microphone works best with this podium?

The XLR input with +48V phantom power is designed for professional condenser microphones, which we recommend for best results. Dynamic microphones also work (phantom power should be switched off). For wireless setups, a wireless receiver can connect via the XLR or 6.35mm input. Our recommended accessory is a cardioid condenser gooseneck microphone for podium-mounted use.

❓Can the equalizer settings be locked to prevent tampering?

Yes, the DSP settings can be password-protected via the Android settings menu, preventing unauthorized changes to the audio configuration. Custom presets can also be set as the default boot configuration.
