Room Mode Correction
To route an incoming AESfEBU two-channel signal to another p aker use an cable with XLR
plugs on both end, to connect the AES/EBU OUT of the fi rst speaker to th AES/EBU IN of
the second speaker.
To route an incoming SfPOIF two-channe l signal to another speaker, use a cable with phono
plugs on both ends to connect the S/PDlF OUT of the first speaker to the
SfPDIF
IN f the
second speaker.
For best re ults when using digital inputs, alway use high-quality cable designed for u e with
digital equipment. We recommend the us of 110 ohm cabling for AESfEBU connections and
75 ohm cabling for SfPOIF conn ctions.

RMCTM Room Mode Correction
When a loudspeaker is placed! in any work space, it and the room behave as a system which,
for better or worse, acts as the reference point for creative decisions . When a room has
inadequate or incorrect acoustic treatment, "room modes" (sometimes called "standing
waves") can result, producing low frequency resonances that give a misleading impression of
bass response and therefore make it difficult to achieve a proper mix balance.
The LSR4300 utilizes a revolutionary technology called RMCTM (short for "Room Mode
Correction") that is designed to correct the problem. RMC analyzes the frequency response of
