As you will see below the SDA amplifiers are highly flexible and can be
used in many different system configurations. Only your creativity in
finding ways to use them is the limit. As always we recommend having as
much available power for the greatest system headroom and lowest
dynamic distortion possible.
SDA4600 Configuration 1 with Alternate Digital Inputs (600W x 4)
These alternate inputs could be used when a pair of Left and Right speakers
are being used with a dedicated 4-channel amplifier to power them. This
could also be used to "double up" on subwoofer channels, for example, if
there is one amplifier being used as a bridged high power amplifier for two
(2) subwoofers and a second amplifier being used with four (4) smaller
amplifiers mounted in pairs. This is common in large rooms where a pair of
high power 18" passive subwoofers are in the front and 2 pairs of smaller in-
wall passive subwoofers are used in the rear, but mounted in groups of two
where you would want to treat the groups as a single subwoofer. This
configuration could be used with an SDA8300 in either Factory configuration
1 (for Center and Surround channels) or in combination with SDA 8300
Configuration 3 and SDA4600 Configuration 2 or 3 for Center Channel as
shown in the next section . Common speakers to be used with this
configuration would include Project Array, any speaker that can be bi-wired
(passive bi-amplification), K2, M2, Everest, SAM1HF/SAM2LF and other
similar speakers.
A good use of this would be to have the Left and Right speakers on an
amplifier using Configuration 1; while the Center channel uses a separate
amplifier in Configuration 2 or 3 as shown at right.

SDA4600 Configuration 2 with Alternate Digital Inputs (1200W x 2)
This configuration could be used with either a LEFT channel or CENTER
channel where a dedicated 2-Channel amplifier is being used. For example,
if you have installed a large front speaker that can be bi-amplified and the
installation requires the best possible dynamic headroom. Common
speakers to be used with this configuration would include K2, M2, Everest
SAM1HF/SAM2LF and other similar speakers.
