The Sierra PRO 32 audio series are high performance routing switchers for balanced stereo audio signals. These units come in a compact 3U (5.25”) frame and can route any or all inputs to any or all outputs. They are companion units to the Sierra Pro XL 3232 and 3216 series video frames and are not stand-alone routing switchers.
Audio Features -
Audio Type - 平衡和非平衡音频可拆卸端子
I输入(电平)调整能力(-10db to +15db) - Each input via RS-232, front panel, or G.R.I.P software
输出(音量)的调整能力(静音, -59.5dB to +15dB) - Each input
无拉链效应 - Sierra Pro XL 路由器使用零交叉芯片技术，它还带有数字音量控制，免去了烦人的拉链声音效应
