Frequently asked questions
What is each unit designed to do?
The 640m routes and manages audio across multiple zones with independent volume control and mute functions per output. The iEQ31 shapes tone across 31 frequency bands per channel and includes noise reduction and feedback suppression for single-source or stereo processing.
Which is better for live sound reinforcement?
The iEQ31 suits live sound if you need precise EQ and feedback control on stage monitors or main outputs. The 640m suits larger installations needing to manage multiple zones (separate rooms, floor sections) independently.
Can either unit handle both professional and consumer audio levels?
The 640m accepts both balanced and unbalanced inputs with impedance specs accommodating pro and consumer gear. The iEQ31 features balanced XLR and 1/4-inch connectors with 40k ohm balanced impedance, standard for professional audio.
What is the key spec difference in audio quality?
Both exceed 113 dB dynamic range; the 640m emphasizes transparent fidelity across its signal chain, while the iEQ31 adds exceptionally low distortion (<0.003% THD+Noise) and 2msec latency for surgical processing.
