SUB) BASS LEVEL -12dB...0...+12dB (wszsytkie głośniki z wyj. SUB) Regulację barwy można rozdzielić na FRONT, REAR, CENTER , ale nie zrobiłem tego z lenistwa i z przyczyn praktycznych - poprostu nie ma to większego sensu. Może dorobię regulację balansu, ale to nic pewnego. Regulacja barwy TRE i BAS nie działa na SUBWOOFER - nie wiem dlaczego Regulacja jednej z barwy TRE lub BAS (nie pamiętam) nie działa na CENTER - nie wiem dlaczego W oryginalnym pilocie jest to rozwiązane chyba trochę inaczej: MASTER CENTER REAR SUB = instrukcja pilota podaje : GŁOŚNOŚĆ TONÓW NISKICH TREBLE = instrukcja pilota podaje : GŁOŚNOŚĆ TONÓW WYSOKICH http://obrazki.elektroda.net/79_1225096919.jpg http://obrazki.elektroda.net/25_1225097036.jpg
