D.2 - Setting up the AMR Active System
Loosely place the speakers and connect the bi-amplification speaker cable supplied to each speaker, using the
connector marked "LS-77".
Speakon connectors are first inserted and then rotated clockwise until they lock in place. To remove Speakon
connectors you need to pull the metal catch backwards and rotate the connector counter-clockwise to unlock
the connector so it can be pulled out. Then route the speaker cables to the location at which the amplifiers will
be placed.
Place the amplifiers considering the amount of reach between the two separate Speakon connectors on the
amplifier side of the bi-amplification speaker cable.
Place the AM-77 CCE as you would normally place your preamplifier or AM-77 amplifier. Confirm that the
AM-77 CCE has been configured as Stereo Pre-Main Amplifier (see page 39 of AM-77 Manual).
Please refer to the connection diagrams overleaf for detailed illustration and note the scenarios presented.
