With 32-bit DSP signal processor and 456 MHz speed, this product has the computing power of up to 3.6 GIPS, ensuring fast and accurate processing.

Technical parameters of the product to consider:

• Signal Processor (CPU): 32-bit fixed/floating point DSP + ARM, 456 MHz: The processor uses a 32-bit DSP (Digital Signal Processing) architecture that enables very precise and fast digital signal processing, and is combined with a 456 MHz ARM processor to ensure high performance and powerful computing capabilities. This processor enables high-resolution audio signal processing and fast processing speed.
• Maximum calculation: 3,6 GIPS / 2,7 GFLOPS: GIPS (Giga Instructions per Second): Indicates how many billions of instructions a processor can execute per second. 3,6 GIPS allows the processor to perform a large number of operations per second. GFLOPS (Giga Floating Point Operations Per Second): Measures the ability to calculate floating point operations, which are extremely important in audio signal processing to achieve high accuracy. 2,7 GFLOPS ensures the processor is capable of accurate and fast calculations for complex audio algorithms.
• Audio delay: 900 μs (analog input to analog output): This latency represents the time from when the audio signal enters until it exits the device. With latency only 900 microseconds, this processor is well suited for applications that require fast response times such as live sound, karaoke, or conferencing.
• A/D and D/A converters: 24-bit: Analog-to-Digital (A/D) and Digital-to-Analog (D/A) converters with resolution 24-bit helps convert audio signals with high precision. This helps maintain detailed sound quality during the conversion from analog to digital signals and vice versa.
• Sampling rate: 48kHz: This is the standard sampling rate in professional audio, allowing for high-resolution and good quality audio reproduction, especially in applications such as radio, recording or broadcasting.
• Frequency response: 20 Hz – 20 kHz (+0,3 dB / -0,5 dB): This frequency range covers the entire range of human hearing, from the lowest frequencies the human ear can hear (20 Hz) to the highest frequencies (20 kHz). This range shows how well the processor can reproduce the audio signal without significantly changing the quality at any frequency within this range.
• THD + N (Total Harmonic Distortion + Noise): <0,01% at +4 dBu (A-weighted / 20 Hz – 20 kHz): THD + N is an important index to measure signal distortion and noise in audio processing. At lower levels 0,01%, this processor can deliver extremely clean and clear sound, with very low distortion throughout the entire frequency range.
• Channel Separation (Crosstalk): Dynamic range > 115 dB A-weighted 20 Hz – 20 kHz, analog via: The channel separation index is an important factor in distinguishing signals between channels. Dynamic range on 115 dB shows that the processor is capable of maintaining good audio quality in dividing the signal between channels without crosstalk.
• Input channels: 12 analog inputs (4 unbalanced, 8 balanced): Multiple input support allows the processor to connect to a variety of audio source devices. The high number of inputs makes it an ideal choice for complex audio systems with multiple signal sources.
• Input impedance 12 kΩ @ 1 kHz: This is a typical input impedance for professional audio equipment, allowing easy connection to other devices without compatibility issues.
• Maximum input level: +24 dBu (THD + N <= 0,3%, 20 to 20kHz, 0 dB gain): The Bose ControlSpace CSP-1248 is capable of accepting very high input signal levels without distortion or noise. This maximum input level allows it to handle signals from high-level devices without problems.
• Equivalent input noise: Phantom power +48V, open circuit, 10mA max per channel: Processor supports phantom power + 48V, providing power to condenser microphones without the need for an external power source. This saves space and ensures stability in the sound system.
• Output channels: 12 (4 analog, 8 digital via AmpLink): The Bose ControlSpace CSP-1248 Controller can output audio signals via 4 analog outputs and 8 digital outputs, helping to distribute sound to many different areas in a large sound system.
• Output impedance: 66 Ω: Output impedance indicates how compatible the processor is with other devices, helping to protect the audio system from problems caused by impedance mismatch.
• Maximum output level: +24 dBu (THD + N <= 0,3%, 22 Hz to 20 kHz): This maximum output level allows the processor to deliver a powerful audio signal without noise or distortion.
• Power supply voltage: 85VAC-264VAC 50/60Hz: This processor can operate over a wide voltage range, from 85 VAC to 264 VAC, making it flexible and adaptable to power systems in different countries and regions.
• Typical AC power consumption: Although this parameter is not fully provided, energy consumption is an important factor when evaluating system performance and efficiency.
• Dimensions: 44 × 483 × 215 mm , and Weight: Not fully supplied. However, at this size, the processor can fit into standard 19-inch racks.
