Frequently Asked Questions about Quantum QM66SP


What are the main features of the Quantum QM66SP?

The ESX Quantum QM66SP is a precision-optimized 6-channel sound processor that combines modern audio processing with Bluetooth control and HD audio streaming. Optimized with an integrated aluminum heat sink, it features AKM Velvet Sound™ analog/digital converters and a DSP chip from Analog Devices™. These components enable full HD audio processing at 96 kHz. The QM66SP offers a processing power of 32-bit and 248 output EQs, as well as time corrections from 0 to 20 ms. The technical specifications include numerous inputs and a range of outputs at 6 V RMS.

How does HD audio streaming over Bluetooth work with the Quantum QM66SP?

The Quantum QM66SP has an integrated Bluetooth® receiver with an antenna, allowing the sound processor to be controlled wirelessly via an app from a smartphone and stream in full HD audio. This provides maximum flexibility in music transmission and usability of sound profiles without a physical connection. The streaming function utilizes the high-quality signal converters of this unit to ensure HD audio quality that is compatible with common music services. The combination of AKM Velvet Sound™ conversion technology with the wireless Bluetooth function grants you a high-level audiophile experience.

What input and output options does the Quantum QM66SP offer?

The Quantum QM66SP sound processor is equipped with various input and output options to ensure high compatibility. The inputs include 6 RCA inputs and 6 high-level inputs via Molex connectors, complemented by an optical S/PDIF input with 192 kHz/24 bit. Additionally, there is a USB Type B input for PC software and an RJ45 for remote controls. The 6 RCA outputs operate at 6 V RMS, ensuring a clear and strong audio signal. These extensive connectors increase the adaptability of this processor.

What are the dimensions of the Quantum QM66SP and how does that affect its installation?

The Quantum QM66SP measures 104 x 41 x 189 mm, making it relatively compact for a sound processor. These dimensions allow for flexible installation in vehicles with limited space, such as under the seat or in the trunk. The aluminum heat sink structure ensures efficient heat dissipation, even in tight installations without additional space requirements. When planning the installation, the dimensions should be considered to optimize placement and ensure proper securing. This compact size increases the number of potential installation locations.

What specific sound processing options does the Quantum QM66SP offer?

The Quantum QM66SP offers comprehensive sound processing options, including up to 248 output EQs and 120 input EQs with 0.5 dB steps for fine-tuning. Additionally, high-pass, low-pass, and band-pass filters ranging from 6-48 dB are available, accompanied by a phase shift function. A delay correction of 0 to 20 ms in 0.01 ms steps is also integrated. This fine granularity allows for high accuracy in sound adjustment. Processing through the advanced Analog Devices™ DSP chip at 294 MHz maximizes audio quality and precision to create desired soundscapes.

How does the Quantum QM66SP ensure high audio quality?

The high audio quality of the Quantum QM66SP is ensured by the combination of AKM Velvet Sound™ A/D and D/A converters and the DSP chip from Analog Devices™. The analog signal processing achieves a signal-to-noise ratio of 106 dB and the digital one of 111 dB with minimal distortion. The analog input has a total harmonic distortion of less than 0.0015%, while the digital input is less than 0.0009%. These values result in pure sound development for a demanding audio experience. The 32-bit processing enhances this effect by allowing the finest acoustic details to be processed distinctly.

What functions does the optional RC-DQ remote control offer with the Quantum QM66SP?

The optional RC-DQ remote control significantly expands the operating options of the Quantum QM66SP. This LCD remote allows easy access and control of the preset sound profiles as well as the adjustment of key parameters directly from the driver's seat. This way, you can make adjustments to the EQ and volume without software access on the PC. Despite its adjustment options, the RC-DQ maintains an intuitive operation, ideal for changes while driving. This functionality significantly enhances the user-friendliness and flexibility of the sound processor by allowing adjustments based on the situation.

What connectivity technologies does the Quantum QM66SP support?

The Quantum QM66SP offers a variety of connectivity technologies, including a Bluetooth interface for HD audio streaming and control via mobile apps. Additionally, there is an optical S/PDIF input at 192 kHz/24 bit for lossless digital audio transmission. USB Type B allows connection to PCs for software configuration, supported by an RJ45 port for remote control or expansion. These integrations ensure that the Quantum QM66SP can be easily connected to various modern audio sources and applicable system setups, significantly enhancing the versatility of the sound processor.

What crossover filter options does the Quantum QM66SP have?

The Quantum QM66SP is equipped with advanced crossover filter options, including high-pass, low-pass, and band-pass filters that can be adjusted from 6 to 48 dB. These filter options allow for detailed adjustments of the crossover to optimally tailor the sound to the specific requirements of your speaker systems. For example, high-pass filters can emphasize high frequencies, while low-pass filters ensure focused bass reproduction. The flexible filter features, combined with the phase shift function, enable particularly precise sound tuning for a harmonious overall experience.

How is the time correction implemented in the Quantum QM66SP?

The time correction of the Quantum QM66SP allows for delaying signals by 0 to 20 ms with adjustments in fine 0.01 ms steps. This function is crucial for adjusting sound delay in multi-channel systems to maximize the coherence and precision of the sound image, especially in complex vehicle acoustic environments. It enables the precise compensation of signal paths originating from differently positioned speakers. This can help minimize spatial asymmetries in the sound field and create a uniformly optimized and synchronized sound image.
