DLA2/4/6 Speaker Level Audio Router
External AmpliÀ er
Some systems utilize an external ampliÀ er for speakers that are connected to the DLA2/4/6.
In A/V receiver or stereo receiver applications, a line-level output (Tape Loop, Monitor Out,
etc.) is connected to the external ampliÀ er (See Figure 2-4). In a Pre-Amp/Processor-based
system, the Pre-Amp is connected to the external ampliÀ er as shown in Figure 2-5.
