Connecting an amplifier, active speakers or a

• Before connecting the JM-8 to an amplification sys-
tem, be sure to switch off both the JM-8 and the
external device.
• Connect the JM-8’s AUDIO OUTPUT sockets to the
line input(s) of your amplifier or mixer.
• After establishing the connections, first switch on the
JM-8, then the amplifier or mixer. See “Turning the

Connecting an external display or a
television
Note: You can’t use the VIDEO jack and RGB connector at the
same time.
Connecting a television
Note: Before you make connections to other devices, you
must turn down the volume of all devices and turn off
their power to prevent malfunctions or damage to your
speakers.
(1) Switch off the JM-8 and the television you’ll be
connecting.
(2) Connect the JM-8 to your television, use a video
cable (commercially available) to connect the
JM-8’s OUTPUT VIDEO jack to the television.
(3) Switch on the JM-8 (see p. 18).
(4) Switch on your television.
(5) Activate the VIDEO OUTPUT

(see p. 64).
(6) (As necessary) Specify the television output format
(see p. 64).
(7) Specify the aspect ratio (ratio between width and
height) for your television.
• The aspect ratio is the proportional relationship
between the width and height of the screen. The
JM-8’s screen has an aspect ratio of 16:9. Televisions
can have an aspect ratio of either 4:3 or 16:9 (wide
screen).

If your television has both a video jack and an
RGB connector
The JM-8’s provides both a VIDEO and an RGB con-
nector. You may use either of these, depending on
the type of connector provided on your television.
We recommend that you use the RGB connection,
because it will provide a higher-quality picture than
the VIDEO connector.
