Description:
KECES Sphono is a type of solid-state phono preamplifier designed to amplify the low-level signals produced by a turntable cartridge. Here are the specifications of the KECES Sphono:
Type: It is a crystal-based phono preamplifier designed to provide high-quality amplification for turntable setups.
Frequency Response: It has a frequency response range of 20Hz to 20kHz, indicating its ability to accurately reproduce audio signals within this range.
Total Harmonic Distortion: The total harmonic distortion is specified as less than 0.002% for MM (Moving Magnet) cartridges and less than 0.009% for MC (Moving Coil) cartridges. This indicates the level of distortion introduced by the amplifier during signal amplification, with lower values being better.
Signal-to-Noise Ratio: The signal-to-noise ratio is specified as 96dB A-weighted for MM cartridges and 82dB A-weighted for MC cartridges. It represents the ratio of the desired audio signal to the background noise, with higher values indicating better performance in minimizing noise.
Input Impedance: The input impedance is 47k ohms for MM cartridges and variable (with selectable options of 56/100/220/470/1k/46k ohms) for MC cartridges. It determines the load that the phono preamplifier presents to the cartridge and affects the frequency response and overall performance.
Input Capacitance: The input capacitance is specified as 100pF for MC cartridges and variable (with selectable options of 47/100/150/220/330/470pF) for MM cartridges. It affects the high-frequency response of the system.
Gain: The gain settings for MM cartridges are 40dB and 46dB, while for MC cartridges, they are 60dB and 66dB. The gain determines the amplification level applied to the cartridge’s signal to match it with the line-level inputs of other audio equipment.
Power Input: The KECES Sphono operates on DC 24V power, which is supplied by the Sphono Power unit.
Chassis: The chassis of the Sphono is made of 4mm aluminum alloy, ensuring durability and providing shielding against external interference.
Dimensions: The dimensions of the Sphono are 300x220x66mm (Width x Depth x Height), making it compact and suitable for integration into audio setups.
Weight: The Sphono weighs 3.5kg, indicating its solid construction and build quality.
The KECES Sphono Power is a linear power supply designed to provide clean and stable power to the Sphono phono preamplifier. Here are the specifications of the KECES Sphono Power:
Type: It is a linear power supply specifically designed for the Sphono phono preamplifier.
AC Input Voltage: It supports two selectable options for AC input voltage – 110V-120V, 60Hz, and 220V-240V, 50Hz, allowing it to be used in different regions with varying power standards.
DC Output Voltage: It provides a DC output voltage of 48V, ensuring sufficient power supply to the Sphono preamplifier.
Power Consumption: The Sphono Power consumes 18W of power during operation.
Chassis: The chassis of the Sphono Power is made of 4mm aluminum alloy, providing durability and protection.
Dimensions: It has the dimensions of 220x220x66mm (Width x Depth x Height), matching the size of the Sphono preamplifier.
Weight: The Sphono Power weighs 5kg, indicating its solid construction and build quality.
These two components, the KECES Sphono and Sphono Power, work together to provide high-quality amplification and clean power supply for turntable setups, ensuring accurate and low-distortion reproduction of vinyl records.
