The APEQ range of hardware equalizers are stand-alone hardware solutions. A PC or MAC is only required to run CONEQ measurement software. After the correction filter has been calculated and generated, it can be easily uploaded to the non-volatile memory of any APEQ equalizer by USB connection. The computer will automatically detect the APEQ unit after connection to a USB port of the computer.
The APEQ range of FIR filter equalizers are delivered in a professional-grade 1U rack-mount device with balanced analogue I/O as a standard. The choice of hardware units consists of two channel units with both analogue only and also analogue and digital I/O. The eight channel model APEQ-8pro DIO is always equipped with both Digital and Analogue I/O.
