Multiple Amplifier Combinations

The Directed 750d/1500d subwoofer amplifiers can also be used in multiples of the master/slave combinations allowing for unlimited expansion to a systems subwoofer section. To use multiples of amplifier combinations the following directions must be adhered to for best results.

Audio signal - Divide the head unit or processor audio signal to the master amplifiers by using RCA Y adapters. Be sure to divide them an even number of times to ensure the input level at each master amplifier is matched.

Remote Sub Level Control - The Remote Sub Level Control cable can be divided several times to connect to each master amplifier. This can be accomplished by using one or

more Directed Remote Sub Level cable splitters. Standard single-to- double phone line splitters and accessories from a local electronics store can also be used.

For systems with more than two master/slave combinations, use multiple single-to-double splitters. Do not use phone splitters that divide the signal more than once per splitter, or splitters designed for multiple uses.

Amplifier configuration - Set up each master/slave amplifier combi- nation as described for the combi- nation type being used. (Refer to the Parallel Synced Gain or the External Synced Bridged section of this guide for amplifier and speaker connection descriptions.)
