توضیحات
از زمان تولید اولین میکسر دیجیتال یاماها در سال ۱۹۸۷ شرکت یاماها در زمینه نوآوری در میکسر های دیجیتال پیشرو بوده است. یاماها برای انواع رویدادها در سالن های کوچک ،سالن های بزرگ ،کنسرت های بزرگ در فضای باز، تولید موسیقی و حتی سیستم های تجاری و موارد دیگر انواع سیستم ها را طراحی و ساخته که کیفیت صوتی و عملکرد عالی و قابلیت اطمینان بالا در آنها در جهان مورد ستایش قرار گرفته است . سری TF-Rack یاماها یک نسخه جمع و جور از سری TF است که دارای عملکرد مشابهی می باشد که به صورت رک مونت در اختیار مهندسان صدا قرار می‌گیرد.
