Description
The DS18 EQX5 is a high-voltage 5-band graphic equalizer with high-level input, built for multi-amp car audio systems where precise tonal shaping and seamless integration matter. It provides independent front, rear, and sub routing with an 8V output for clean, dynamic performance.
- 5-Band Graphic Equalizer: Frequencies at 50 Hz, 315 Hz, 800 Hz, 2.2 kHz, and 12 kHz with ±12 dB boost/cut (±15 dB for subwoofer frequencies) for precise tonal adjustment across the spectrum.
- Three Stereo RCA Outputs: Separate outputs dedicated to driving front, rear, and subwoofer amplifiers, enabling dedicated gain staging for each zone of your system.
- 8V Output with Hi-Level Input: High headroom output paired with a built-in Hi-Level Converter to generate low-level RCA from high-level sources for versatile integration.
- Independent Controls: Master volume, sub level, front/rear fade, and main/aux input selection provide flexible tuning and easy on-the-fly adjustments.
- Crossovers and Filters: Passive crossover with a fixed 120 Hz point and 12 dB/Octave slope for bass management and subwoofer shaping.
- Audio Performance: Frequency response 10 Hz–30 kHz; S/N ratio 100 dB; THD 0.005% for low-noise, low-distortion operation.
- Inputs and Connectors: Main (RCA) and Aux (3.5 mm) inputs; Nickel-plated RCA connectors for robust signal integrity; Hi-Level input present; Remote turn-on output supported.
- Power and Physical: Operating voltage 11–15 V; Subwoofer output at 8 V; Headroom 20 dB; Dimensions 7" L × 4.4" W × 1.18" H; weight 1.5 lb; Satin Black finish with blue backlighting.
- Install and Accessibility: Mounting brackets included for placement next to the source unit or under the dash, with front-panel controls accessible from the driver’s seat.
In a typical multi-amp setup, the EQX5 provides precise band control and clean signal routing to front, rear, and sub amps, while its high-level input and 8V output offer straightforward integration and headroom. The fixed 120 Hz sub crossover and 12 dB/octave slope give you a reliable bass boundary, complemented by a low-noise 100 dB signal-to-noise ratio and very low distortion for clear, accurate sound reproduction.
