STEREO SUB OUT [+4dBu]
LINK OUT R [0dBu]
*1. Signal levels in blocks and level diagram are indicated under the conditions below.
• LINK OUT R, ST SUB OUT R: plugs are connected
*2. Signal level with plugs unconnected to LINK OUT R and ST SUB OUT R.
• When the same phase signal are sent to L and R buses, SPEAKER output level and ST SUB OUT output level increase in 6 dB.
• When the stereo signal are sent to L and R buses, SPEAKER output level and ST SUB OUT output level increase in 3 dB.
*1. ブロック内のレベル表示及びレベルダイアグラムは、
【Level VR: MAX】【LINK OUT R, ST SUB OUT Rにプラグ挿入】で表示
-50dBu *2. LINK OUT R, ST SUB OUT Rにプラグを挿入しない場合のレベルについて
・L, Rバスに同相信号を送った場合、SPEAKER出力、ST SUB OUT出力が6dB upする。
・L, Rバスにステレオ信号を送った場合、SPEAKER出力、ST SUB OUT出力が3dB upする。
