Yamaha Computer Drive AI8 Руководство пользователя

  • Привет! Я прочитал руководство пользователя по аналоговым картам ввода/вывода Yamaha LMY2-ML, LMY4-AD и LMY4-DA. Я могу ответить на ваши вопросы о характеристиках этих карт, их установке и использовании с блоками AI8 и AO8. Например, я знаю, сколько карт можно установить в AI8, какой диапазон входного уровня поддерживается и какое разрешение АЦП используется. Спрашивайте!
  • Сколько карт можно установить в AI8?
    Какой диапазон входного уровня для LMY2-ML?
    Какой выходной импеданс у LMY4-DA?
    Какое разрешение АЦП у карт LMY4-AD?

hank you for choosing the Yamaha input card for the analog input box AI8, and the Yamaha output card for the analog
output box AO8.
Be sure to ask an authorized Yamaha service engineer to install the cards. Do not install the cards yourself.
The connecting screw also functions as the ground. Secure the screw tightly.
