Introducing the E3 AP-48 Crossover

The E3 AP-48 crossover is a powerful signal processing unit with a wide frequency response range from 20Hz to 20kHz, extremely low distortion (<0.003%), and a dynamic range of up to 110dB, helping to reproduce sound faithfully and in detail.

The device is also equipped with a SHARC ADSP-21488 DSP chip with a speed of 400MHz, allowing for high-precision and fast digital audio processing, meeting the requirements of professional sound systems.

Technical parameters of the product to consider:

• A maximum input and output signal level of 18 dBu ensures powerful and stable signal processing: The E3 AP-48 crossover supports maximum input and output signal levels of up to 18 dBu, allowing the device to receive and transmit audio signals at high intensity while maintaining stability.
• Extremely low distortion results in a more accurate and cleaner sound: The device boasts extremely low total harmonic distortion (THD+N), just under 0.003% at 1kHz @ 4dBu. This indicates that the signal processing virtually eliminates distortion of the original sound. As a result, the audio system retains detail, clarity, and fidelity after passing through the crossover.
• A wide frequency response range helps to reproduce the full range of sound: The E3 AP-48 crossover has a frequency response range from 20Hz to 20kHz with an accuracy of only ±0.2dB. This is the standard frequency range for the human ear, allowing the device to process and fully separate the sound frequencies from deep bass to high treble. This ensures that the subwoofer, midrange, and tweeter speakers operate within their respective frequency ranges, enhancing the overall performance of the speaker system.
• A large dynamic range and a high signal-to-noise ratio result in cleaner sound: The device boasts a dynamic range of 110dB and a signal-to-noise ratio (S/N) of -110dB. This means the audio signal is significantly stronger than the background noise, resulting in clearer sound and minimizing static or interference when the system operates at high power levels.
• Powerful SHARC ADSP-21488 DSP processor: The crossover is equipped with a SHARC ADSP-21488 DSP chip with a processing speed of 400MHz and floating-point computing capabilities. This processor allows for the execution of complex audio algorithms such as crossover, parametric EQ, limiter, and delay with high accuracy, ensuring smooth and stable operation of the sound system.
• High-quality ADC and DAC signal converters: The device uses an ADC CS5361 and a DAC CS4382A with a dynamic range of 114dB. These are high-quality signal processing components that convert analog signals to digital and vice versa with high accuracy, minimizing signal loss during processing.
• Advanced signal processing system with multiple filters and EQ: The E3 AP-48 crossover supports a wide range of professional filters such as Bessel, Butterworth, and Linkwitz-Riley, with slope levels from -6dB to -48dB/oct. Additionally, it features a multi-band parametric EQ for fine-tuning each frequency range, ensuring balanced speaker system performance suitable for various sound environments.
• Supports modern Ethernet limiters, delays, and control: The device features independent limiters for 12 channels, protecting speakers from overload. A delay function of up to 218ms allows for precise timing between speakers for synchronized sound. Additionally, Ethernet control enables technicians to easily manage and set up the sound system remotely.
