The Evolution 707 does not require any type of special rack or cabinet for installation. The
component measures 17.3w x 9.8h x 20.5d in. or 43.8w x 24.8h x 52d cm and requires at
least two inches (5 cm) of clearance on each side and four inches (10.2 cm) of clearance
above to provide adequate ventilation. The one-inch (2.5 cm) clearance below the compo-
nent, provided by the feet, is adequate. For installations inside cabinetry, extra ventilation
may be necessary.
The Evolution 707 has superb regulation and does not require a dedicated AC circuit.
Avoid connections through extension cords or multiple AC adapters. High quality 15 amp
grounded AC strips are acceptable. High quality AC line conditioners or filters may be used
if they are grounded and meet or exceed the unit’s power supply rating of 100 VA. Use the
Evolution 707 only with the power cord supplied.
The Evolution 707 can be operated using the factory defaults shipped with the component.
For best performance, play music after configuring the systems loudspeakers. This guide
outlines the steps and connection considerations from initial setup through loudspeaker
configuration.
Connect the Evolution 707 to the rest of the components in your system. Connect analog
and digital sources first, then connect the amplifier(s).
You need OSD to view the setup menu. Connect any OSD output on the Evolution 707 to
the appropriate input on your video display. OSD is available from all outputs.
The Evolution 707 has the ability to output 1080p/60 Hz digital video only from the HDMITM
output. If the installation intent is to take advantage of digital video, your monitor,panel, or
projector must be able capable of receiving 1080p video via HDMITMor DVI formats.
Zone 2 only has the ability to pass analog video output up to 1080i. When a source is con-
nected to the Evolution 707, make sure that the output is not HDMITMdigital for zone 2 use. In
most cases, there is more than one type of video output on your source component. Use the
component, S-video, or composite video outputs for zone 2.
IMPORTANT:If your video input is exclusively HDMITM/DVI, only HDMITM digital video is
output for viewing. There is no way to get analog video output via component, S-video, or
composite connections from the Evolution 707, either in the main zone or in zone 2.
The Evolution 707 does not have the ability to send digital audio information to zone 2
audio outputs. Only analog signal will function in zone 2. If the source is connected via dig-
ital only, run a separate analog input into the Evolution 707 specifically for zone 2, and con-
figure it accordingly.
Plug the AC power cordinto the wall, and place the back panel switch (75) in the on posi-
tion. The power/stand-by LED (2) illuminates red. Press the power button on the front
panel or the power key on the remote control (1) to switch the Evolution 707 from stand-by
to the operational mode. The power/stand-by LED illuminates blue.
Press the MENU button or remote control MENU key to enter the setup menu. The MAIN MENU
screen appears on the video display. The front panel display reads MENU MODE and all OSD
outputs activate simultaneously. Tune the video display input to match the selected OSD
video connection.
