controls (Volume, Balance, Bass, Treble) may be connected to the pre- amp-level inputs at the same time as a powered radio/tape unit is connected to the speaker-level inputs. This provides a higher performance alternative to an FM Modulator connection when you wish to add CD capability to a factory installed cassette radio. Switching from one source to the other is as simple as turning the desired source on and turn- ing the undesired one off — no addi- tional switches or relay connections are needed.

Other Components

The system options of the GTS100 are numerous. All JBL amplifiers are designed with sufficient adjustment range to match with the accepted “nor- mal” voltages and impedances used by virtually all car audio components. With very few exceptions, the GTS100 will match correctly to any equipment you already have.

Typical Applications

The following diagrams show the most common basic system configurations using the GTS100. More elaborate systems are formed by using a combination of these “building blocks.” For additional ideas, refer to the “Add On and Upgrade Section” near the end of this manual.
