The LCA16, in conjunction with an automatic mixer (such as the Lectrosonics Modular Audio Processor system) controls the gain of each speaker, individually, in response to activity on any of the microphones in the sound system. Any speaker can be attenuated or turned off completely by the logic output signals from the automatic mixer channels. In addition, each channel includes a balanced line level output which may be used to drive external amplifiers.
Each of the 16 output channels in the LCA16 provides 5 Watts into a 4 Ohm speaker (3 Watts into an 8 Ohm speaker) and a balanced line output. A straight forward switch matrix allows each individual output channel to be attenuated by any combination of the 16 logic inputs.
The LCA16 has integral power supplies and is designed for mounting in a standard 19-inch equipment rack. Three front panel LEDs per channel indicate the level of attenuation. The switch matrix and attenuation level controls are located behind a removable panel to prevent tampering or accidental mis-adjustment.
