Features & Benefits

Precision 31-Band Parametric EQ - Professional-grade 31-band equalization provides surgical control over your entire audio spectrum from 20Hz to 20kHz. Each band can be precisely adjusted to compensate for cabin acoustics, speaker characteristics, or personal preferences, allowing you to sculpt the perfect tonal balance for your specific vehicle environment.

High-Resolution 192kHz/24-Bit Processing - Studio-quality digital signal processing preserves every nuance of your music with exceptional accuracy. The 192kHz sampling rate and 24-bit depth ensure transparent audio handling without the digital artifacts common in lower-resolution processors, maintaining the integrity of high-quality source material.

Advanced Time Alignment - Individual channel output delay adjustment up to 7.354ms allows precise sound staging correction. Compensate for asymmetrical speaker placement and varying listener distances to create a perfectly centred soundstage, transforming your vehicle's cabin into an optimized listening environment regardless of seating position.

Exceptional Signal-to-Noise Ratio - With >108dB signal-to-noise ratio, the DTX460S delivers studio-quiet backgrounds that reveal subtle musical details often lost in typical car audio environments. The extraordinarily low noise floor allows dynamic recordings to breathe while maintaining clarity during quiet passages.

Factory System Integration - High-level input sensing enables seamless integration with factory head units, automatically detecting audio signal and powering on without additional trigger wires. This factory-friendly design simplifies installation in vehicles where low-level RCA outputs aren't available, making premium sound accessible in stock audio systems.

Compact Class A/B Design - Despite its powerful DSP capabilities, the DTX460S measures just 185×121×43mm, fitting easily under seats, behind panels, or in compact installation locations. The Class A/B topology balances sound quality and efficiency, delivering natural, transparent amplification without the heat and current demands of pure Class A designs.

Frequently Asked Questions

Can this amplifier work with my factory head unit Yes, the DTX460S features high-level inputs specifically designed for factory head unit integration. The auto turn-on function detects speaker-level signals, eliminating the need for low-level RCA connections or complex trigger wire installations.

What's the difference between Class A/B and Class D amplifiers Class A/B amplifiers like the DTX460S prioritize sound quality and natural tonal characteristics over maximum efficiency. They produce less heat than pure Class A designs while maintaining superior audio transparency compared to Class D switching amplifiers, making them ideal for critical listening applications.

How many speakers can I connect to this amplifier The DTX460S provides 6-channel RCA pre-amp outputs, allowing connection to external amplifiers for a complete 6-channel system. Channels 1-4 deliver 50W amplified power directly to speakers, while channels 5-6 function as signal-processed line outputs for subwoofer or additional amplification.

Do I need tuning software to adjust the DSP settings The DTX460S requires compatible tuning software and interface for accessing DSP functions including the 31-band EQ, time alignment, and crossover settings. Contact your installer or check Clarion documentation for specific tuning software requirements and compatibility.

Will this fit in tight installation spaces Yes, the compact 185×121×43mm dimensions make the DTX460S ideal for space-constrained installations. The small footprint fits easily under seats, behind trim panels, or in limited mounting locations where larger amplifiers won't accommodate.

Compatible With / Goes Well With

Recommended System Components:

• High-quality 6.5" or 8" component speaker systems
