MYTHO 8 ACTIVE TWO-WAY 8” DSP MONITORING SYSTEM
APPLICATIONS • Professional recording studios • Project studios • Audio/video production facilities • Home Recording • Hi-End home music reproduction • Mid-Large size control rooms FEATURES • True active 200 W + 100 W class AB design • Dedicated DSP processing • Fully featured input board • 8” neodymium ICC vented woofer • 1” aluminum dome tweeter • Constant directivity wave-guide • Die cast aluminum cabinet • Reflection free cabinet design • Low distortion reflex port
MYTHO 8 is a two-way reference studio monitor equipped with two separate AB amplifiers - 200 W for the low frequencies and 100 W for the high - unparalleled for low distortion and natural sound. It features a high quality large metal dome tweeter for the best vocal reproduction and a 8” neodymium vented woofer with a large sized 51 mm voice coil that guarantees very high energy for tight and controlled bass reproduction and perfect thermal stability with minimum power compression. The magnetic circuit features a special air ventilation to reduce air compression, air noises and minimize distortion in large excursion situations. Thanks to the deeper low frequencies reproduced by its 8” woofer, the MYTHO 8 is perfect for medium to large control rooms. A dedicated high quality DSP is provided on board. The cabinet is made in aluminium, internally braced and reinforced to improve low frequencies behaviour and reduce resonances. Ultra low noise operational amplifiers and a dedicated analogue-digital converter take care of signal input amplification and translation in the digital domain. The signal processing is executed from a dedicated high quality Dsp. The digital choice guarantees fine crossover tuning and accurate multipoint two way equalization independent from temperature and component tolerances. Soft signal clipping and transducers protections are integrated in the Dsp processing. A special algorithm runs in RCF during the final speaker testing to calibrate the speaker sensitivity and cancel even the smallest difference from the ideal curve response
