Speaker Settings in a Surround Sound
Receiver or Processor
If you are using a contemporary surround sound receiver or processor you need to set the
speaker parameters properly to maximize your system's performance. After your speakers
are properly connected, turn on the receiver or processor, enter the setup menu and
navigate to the speaker settings menu. Adjust the speaker settings as follows:
Surround Sound Receiver or Processor Speaker Settings
Speaker Size - If you are using a separate subwoofer, we would generally recommend that
you set the Reference 3.5's to "Large" initially in the receiver/processor speaker setup
menu. This will allow them to run full range in conjunction with your subwoofer. In many
cases, having multiple woofers producing high-quality bass in a system can result in
smoother bass response throughout the room with more "good seats" for cinema or
music reproduction. Our listening has convinced us that the Reference 3.5's deliver their
best overall sound when they run full range.
However, if you find the bass seems unacceptable, try setting the Reference 3.5's to
"Small" in the receiver's setup menu. If the electronics allow, start with the crossover
frequency set to 80Hz. And yes, that means you are bypassing the Reference 3.5's deepest
bass capability. However, the best room location for midrange and high-frequency imaging
and soundstaging is out, away from the back and sidewalls. And the best location for
smooth, deep bass response in multiple locations in most rooms is typically up against the
front or sidewalls, halfway or one-quarter way out from a corner (In this location you will
get less overall bass impact from the sub(s) than if you place them in a corner. But you will
enjoy good bass performance at more places in the room). This will let you optimize your
system's imaging and bass performance by placing the subs accordingly, thereby getting
the most from the Reference 3.5's by keeping them a reasonable distance from reflective
walls.

OPT Connection
The OPT Level 2 input (dielectric countermeasure technology) is located above the binding
posts for mating with our optional Reference 3.5 loudspeaker wire. Inserting the banana
plug attached to the end of this speaker cable into the OPT jack on the speaker effectively
makes the connection much closer to the drive source, as it is shielding the speaker wire
to maximize the benefit of this wiring scheme. This allows the end user to place the
speaker wires directly on any type of flooring material - including carpet - without concern
for dielectric interactions that can reduce definition in the sound.
Should you choose not to use AGA speaker wire, a slightly less effective OPT variation can
be engaged by using the supplied jumper. Insert one end into the positive speaker input
terminal on the 3.5 and the other end into the OPT jack above (Figure 1).
