JBL Mastering the Input Panel Configuration for SR-X Series Systems

INPUT PANEL

Internal Network Mode Selector

All SR-X models are fitted with the internal network mode selector.

The ability to select the mode of operation provides the sound system user flexibility in the system configuration, and also permits the system to be upgraded at a later date. By simply removing the input panel and changing the position of a heavy duty connector, the system can be configured as either a bi-amp or a passive system. After replacing the input panel, the network position is indicated on the connector

mis-configuration.

In passive operation, a system can be operated with a minimum of only one amplifier and no additional system controllers. In bi-amp operation, the system can be operated for maximum transducer performance and will require the use of additional amplifiers-and an electronic crossover (see "Crossovers and Controllers"). For Sub systems with more than one transducer, the same ability to select the mode of operation is provided - but instead of bi-amp/passive selection, the input can be configured for either parallel woofers (4 ohm) or individual transducer access

(2 x 8 ohm). This can be useful for assuring maximum power transfer from the amplifier to the transducers.

Please Note: There are no passive network components in the circuit when the

Bi-amp mode is selected. (Except: SR4732X and SR4735X which retain a crossover section between midrange and HF.)

Changing the Input Mode Connector

1.Remove 6 connector plate retaining screws and remove the plate.

2.Turn plate over and locate the male connector.

3.Pull out connector and firmly place in socket of desired system mode - you should be able to see the yellow indicator in the desired mode window.

4.Replace plate and secure with 6 screws.

Please Note: For SR4715X - SR4719X, the connector is split to permit discrete mode operation.
