Review: TOA A-2120D AS Amplifier
A review of the Volt Line amplifier TOA A-2120D AS, which can connect a large number of speakers, ideal for wired PA and public-address systems.
Last time, we talked about the Low Impedance amplifier. We cannot leave out another type of amplifier, the Volt Line amplifier. This type of amplifier can connect a large number of speakers, making it ideal for wired PA systems, public-address systems, and background music. The Volt Line amplifier we will introduce today is the TOA A-2120D AS. Let's take a look at what functions it has.
