Names of Things and What They Do
After connecting two SA-300s together with one or two
audio cables (1/4-inch phone type), you can easily play
back high power sounds (350 W + 350 W) in stereo.
6. STEREO LINK IN Jack
When using Stereo Link, the audio output by the
STEREO LINK OUT L or STEREO LINK OUT R jack on
the other SA-300 is input here.
You can use it as an external input jack also.
Input level is 0 dBu.
* All Channel 4 LINE jacks function as mono inputs when the
STEREO LINK IN jack is in use.
7. STEREO LINK OUT Jacks (L/R)
Connect this jack to the STEREO LINK IN jack on the
other SA-300 when using Stereo Link.
If you are not using the SA-300’s speakers, but using
external amp speakers instead, the output from the left
or right channel is taken here.
When the STEREO LINK OUT L jack is used, the left
channel audio is not played through the SA-300’s
speakers. In the same manner, when the STEREO LINK
OUT R jack is used, the right channel audio is not played
through the SA-300’s speakers.
Output level is 0 dBu.
* Signals output from these jacks are not routed through the
MASTER section (EQUALIZER, LOW BOOST, WIDE,
VOLUME).
For further instructions on connecting with Stereo Link,
refer to “About Stereo Link” (p. 15).
8. LINE OUT Connectors/Jacks
Mixers, recording equipment, and other such devices are
connected here. Nominal output level is +4 dBu.
This section includes balanced output compatible XLR
type connectors (left and right stereo output) and 1/4-
inch phone jacks (stereo output). You can use the XLR
type connectors and the 1/4-inch phone jacks
simultaneously.
Output is in mono when only the left 1/4-inch phone
jack is connected.

9. GND LIFT Switch
Using external equipment connected to the LINE OUT
connectors may result in generation of the “hum” of loop
ground noise. If this occurs, you may be able to mitigate
the problem by sliding this switch. Normally, this is set
to “OFF.”
ON: Pin 1 is disconnected from the SA-300’s ground.
OFF: Pin 1 is connected to the SA-300’s ground.

SPEAKER Jack
Use this jack to output sounds to the SA-300W
subwoofer.
Use the special connection cable included with the unit
to connect to the SA-300W’s INPUT jack. This provides
an even more powerful low end to the sound.
* Turn off the power on the SA-300 before connecting or
disconnecting cable.
Connect only the SA-300W. Never connect any other
equipment.
Be sure to use only the connection cable included with
the unit to connect the subwoofer. Do not use ordinary
audio cables.
