Know before you buy
The two-chassis construction physically separates the sensitive audio circuits from the power supply and control systems. This isolation prevents electromagnetic interference and vibration from affecting the signal, resulting in greater transparency and sonic accuracy.
Yes, the 850P features a 'home theater ready' mode. This allows you to configure specific inputs to bypass the preamplifier's volume control, enabling seamless integration with an external surround sound processor.
The internal suspension system is designed to minimize microphonics, which are unwanted vibrations that can color the audio signal. By decoupling the sensitive components from external mechanical noise, the system produces a cleaner, more lifelike sound.
The i2 DCf (Independent Inductive DC Filtering) provides dedicated, clean power to every integrated circuit in the unit. This ensures that each component operates with maximum stability, which is essential for maintaining a low noise floor and high signal fidelity.
Yes, the 850P includes a gain offset adjustment feature. This allows you to calibrate the input levels for each source, ensuring that your volume remains consistent when switching between different devices.
The 850P is highly versatile, offering a total of eight inputs: three pairs of balanced XLR connections and five pairs of single-ended RCA connections.
