Phones Output

4
The Phones output allows you to connect headphones for private listening.
This output accommodates standard stereo phone (1/8") plugs. Plugging
in a set of headphones does not cut off the signal to the outputs. Use the
Speaker Selector to turn off the speakers. The settings of the Function
Selector and the Tape Monitor Control determines which source is heard.
To listen to or monitor the component connected to the Tape input set
the Monitor Control to the Tape position. For all other inputs leave the
Monitor Control in the Source position and select the source you want
to listen to with the front panel Function Selector.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.

Media Player

5
A 3.5mm (1/8") stereo input socket for a "Media Player" is provided on
the front of the amplifier and is selected by setting the function control
to (AUX2). Any portable stereo cassette, compact disc player or hard
disc playback device can be connected via this input. If the device you
are connecting has its output via the headphone socket then note that
you must adjust the volume control on the player for sound to be heard.
Should the sound be loud and distorted turn down the volume on the
player and if it is only just audible through the speakers even when the
amplifier volume control is turned up fairly high then adjust the volume
control on the player.
NOTE: When the 3.5mm (mini jack) is inserted into the Media Player
socket the rear input called AUX2 is disconnected. Removing the 3.5mm
plug from the Media player socket will allow the rear AUX2 input to
function.

Audio Controls

Volume Control

0
Turn the controls clockwise to increase the volume, or counter clockwise
to decrease the volume.

Balance Control

-
The Balance Control adjusts the left-to-right balance of the sound output.
Normally the control should be left in the center position. In some situations,
typically when the main listening position is not ideally centered between
the speakers, it may be necessary to adjust the control to achieve proper
left-to-right balance. Turning the control counter-clockwise shifts the sound
balance to the left. Turning the control clockwise shifts the sound balance
to the right.

Tone On/Off Switch

9
When the Tone Switch is in the Off position the Bass and Treble Control
(Tone Control) circuits are bypassed to ensure the purest possible sound.
Leave the Tone Switch in the Off position unless you want to use the Tone
Controls. Turn the Tone Switch to the On position if you want to adjust
the Tone Controls.
RA-10 Stereo Integrated Amplifier

Bass and Treble Controls

8 9
When the Tone Switch is in the On position, turning the Bass and Treble
Controls adjusts the tone balance of the sound. Turn the Controls clockwise
to increase the bass or treble output. Turn the Controls counterclockwise
to decrease the bass or treble output.
A properly setup high-performance audio system produces the most
natural sound with little or no adjustment of the tone controls. Use these
controls sparingly. Be particularly careful when turning the controls up
(clockwise). This increases the power output in the bass or treble range,
increasing the load on the amplifier and speakers.

Function Control

q
The Function control selects the input signal source. The signal selected
by the Function control is the one you hear, as long as the Monitor
control is set to the Source position. (See the following section.) The
signal selected by the Function control also goes to Preamp Outputs and
the Tape Outputs. Turn the front panel Listening Selector to the source
you want to listen to.

Monitor Control

=
When the Monitor Control is set to the Source position, the signal you
hear, and which goes to the Preamp Outputs, is selected by the Function
Control. To listen to the signal from a recorder connected to the Tape
Inputs, set the Monitor Control to the Tape position. When the Monitor
Control is in the Tape position, the signal from the Tape Input also goes
to the Preamp Outputs.
The signal that goes to the Tape Output is always selected by the
Function Control. When you are recording with a unit that has monitoring
capabilities, you can listen to the sound just recorded by setting the
Monitor Control to the Tape position

12V Trigger Outlet

Some audio components can be turned on automatically when they
receive a 12V turn on "signal". The two12V Trigger Outputs of the RA-
10 provide the required signal. Connect compatible components to the
RA-10 with a conventional 3.5mm mini plug cable. When the RA-10
is in turn off mode, the trigger signal is interrupted, so the components
controlled by it are turned off.

Protection Indicator

The RA-10 has both thermal and over-current protection circuitry that
protects the amplifier against damage in the event of extreme or faulty
operating conditions. The protection circuits are independent of the audio
signal and have no impact on sonic performance. Instead, the protection
circuits monitor the temperature of the output devices and shut down the
amplifier if temperatures exceed safe limits.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplifier will stop playing and the
LED indicator on the front panel will light up.
