Description
The red PSI Audio Sub A225-M is a powered subwoofer designed to seamlessly extend the bandwidth of all PSI Audio's studio monitors. The 300W Class-G amplifier powers the two 10.2" woofers to provide a frequency response of 24 to 100 Hz at an SPL of 116 dB (half space). The double-box MDF enclosure offers a built-in anti-resonance system, while the amplifier unit is acoustically uncoupled to provide uncolored performance without artifacts. The rear panel offers two XLR inputs and outputs for working with satellite speakers and is well suited for stereo and multi-channel (surround) monitoring. The level / input sensitivity control helps audio input signal calibration, while the "Roll-Off" control aligns the low frequency response to room conditions. The PSI Audio Sub A125-M includes a power cord, anti-slippage stickers, and an individual frequency response diagram.None Built-in anti-resonance system in a double box cabinetClass-G low temperature amplifier stageAmplifier unit acoustically uncoupled from speaker cabinetReal balanced input with outputs for satellite systemsProtection circuits with overload indicatorDesigned for stereo and multichannel monitoringMagnetically shielded for use close to video monitorsPhase and amplitude response compatible with all PSI Audio monitorsAdaptive Output Impedance (AOI) Technology: The AOI system is made up of a system that detects the movement of the membrane and the coil, as well as a filtered counter reaction. This is then tuned to achieve ideal dampening rate for each frequencyCompensated Phase Response (CPR) Technology: The CPR system is made up of several all-pass filters, each acting in a specific range of frequency and together obtaining a Compensated Phase Response. This provides a constant group delay that is kept to the bare minimum through our entirely analog technologyPhantom Standby Control (PSC) Technology: The PSC technology enables to remotely activate and deactivate the standby mode of your loudspeakers through the signal cable
