In contrast to the systems described above, this kind requires multiple amplifiers (at least one per source, but usually one per zone). This kind of system could be assembled from separate components (e.g. a splitter-router- matrix mixer , a processor, amplifiers and control panels), though knowledge of professional audio equipment and ...
The Play:5 is the current luxury model of the Play line of products, with the first generation having two tweeters and drivers plus a subwoofer, with 5 Class-D amplifiers. [12] [13] However, the second generation has three tweeters and mid-woofers, with 6 Class-D amplifiers, in a phased array. [14] Like its brother products, it also has an ...
Threshold Audio is a high-end audio equipment manufacturer originally established in California in 1974 by audio engineer Nelson Pass and graphic designer René Besne. The company, today based in Houston Texas, manufactures mono-block and stereo power amplifiers, multi-channel power amplifiers and stereo control amplifiers.
Depending on local practices, these amplifiers usually amplify the audio signals to 50 V, 70 V, or 100 V speaker line level. [16] Control equipment monitors the amplifiers and speaker lines for faults before it reaches the loudspeakers. This control equipment is also used to separate zones in a PA system.
Multiple amplifiers can be combined together via transformers to yield higher voltage and higher current capacity lines. For instance, three 70-volt amplifiers have been used to make a 210-volt line by connecting them to a special-purpose external output transformer that has three primaries and a single secondary.

A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...
