- Even if the remote control unit is operated ithin the
effective range, remote control operation may be impossible
if there are any obstacles bet een the unit and the remote
control.
- If the remote control unit is operated near other appliance
hich generate infrared rays, or if other remote control
devices using infrared rays are used near the unit, it may
operate incorrectly.
- The po er is turned on/off (standby) by pressing the
POWER button on the remote control unit in standby mode.
Precautions concerning batteries
-Be sure to insert the batteries ith correct positive+ and
negative – polarities.
- Use batteries of the same type. Never use different types of
batteries together.
- Rechargeable and non-rechargeable batteries can be used.
Refer to the precautions on their labels.
- When the remote control unit is not to be used for a long
time (more than a month), remove the batteries from the
remote control unit to prevent them from leaking. If they leak,
ipe a ay the liquid inside the battery compartment and
replace the batteries ith ne ones.
- Do not heat or disassemble batteries and never dispose of
old batteries by thro ing them in a fire.
REMOTE CONTROL OPERATION RANGE
Use the remote control unit ithin a range of about 6
meters (20 feet) and the angles of up to 30 degrees aiming at
the remote sensor.
BATTERY INSTALLATION
1. Remove the battery compartment cover.
2. Insert t o “AAA” dry batteries.
Make sure that the batteries are inserted ith their
positive “+” and negative “-” poles positioned correctly.
3. Close the cover until it clicks.
If the distance required bet een the remote control unit
and main unit decreases, the batteries are exhausted. In
this case, replace the batteries ith ne on
NOTE: Direct sunlight or very bright ambient lighting may

CONNECTING THE SPEAKERS AND AUDIO SOURCES (CD, TUNER, D D etc.)
Be sure to connect the polarities of the speaker system and the speaker terminals correctly (+ to +, - to -).
When make the connection, please refer to the connection diagram. Make sure that all the units are s itched off during any
connection. The RCA sockets on your SA-300SE are color coded for your convenience. Red and hite are RIGHT and LEFT audio
respectively.
Use high quality RCA-interconnect and speaker cables for optimum performance and reliability. Ensure that all cables and sockets
are not damaged in any ay and all sockets are firmly pushed home.
QUICK START
1. Connect the speakers to the speaker terminal and sources to the relevant terminals and rear input sockets on the back
panel of the unit.
2. Plug in the AC po er cord.
3. Press the POWER s itch on the back panel of the unit, and then press stand-by po er s itch on the front panel (or
remote controller) to turn on the amplifier.
4. Press the required input selector. And enjoy.

FUNCTION AND OPERATION
Turn ON/OFF the unit
1. Connect the po er cord to the rated AC socket. Press the POWER ON/OFF s itch (on the rear panel), the unit has been turned
into stand-by mode.
2. Press the STANDBY button (1/ front panel or remote controll) to turn on the unit. Press the STANDBY button again to turn off
the unit.
Input function selection
After the unit having been turned on, press the source input button to choose the your desired input signal source. For example,
CD button selects the CD (or other line-level source) connected to the CD sockets as the active input, TUNER button for the
connected tuner and so on. Blue LED indicator at every button indicates hich input source is active.
Release the source button at your desired input source, during this procedure, e advice the volume to be decreased. Please note,
that SA-300SE doesn’t have a built in phono stage and corresponding input socket. If you ish to connect a turntable to the
amplifier, you should use some of the commercially available phono preamp-stages, hich can be connected to any of the line
input sockets. Contact your dealer about the suitable phono stages for your amplifier.
Speakers selection
After the unit having been turned on, press the Speakers A button, to select the main speakers. If you have connected additional
pair of speakers, you can choose to listen to the main pair, the additional pair (speakers B) or both. The blue LED indicator ill
indicate hich option is in use. Please use speakers ith an impedance of minimum 4 ohms or more.
Remote control handset

General
When you’ll connect the amplifier into your system for the first time, please note that as ith most high quality electronic units,
it ill require the burn-in time of fe dozens of hours, until the full sound performance ill be achieved. Due to our task for the
maximum sound quality of this amplifier, e have omitted all filters and tone controls, hich are on the signal path and hich can
affect the sound. If you ish to enhance the bass reproduction of your speakers set, you can use any commercially available
active (po ered) sub oofer ith a RCS output, hich should be directly connected to the corresponding SUB OUT socket on the
rear panel.
