Official Manual for Rotel RA-03 Stereo Integrated Amplifier

RA-03Stereo Integrated Ampliﬁer

Phones Output 4

The Phones output allows you to connect headphones for private listening. This output accommodates standard stereo phone (1/4”) plugs. If your headphones have another type of plug, such as a 1/8” mini-plug, you will need an adapter plug. Contact your authorized Rotel dealer, to get the correct adapter plug. 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 or press the corresponding source button on the remote control.

NOTE: Because the sensitivity of speakers and headphones can vary widely, always reduce the volume level before connecting or disconnecting headphones.

Audio Controls

Volume Control 0 a

Turn the control 0 clockwise to increase the volume, or counterclockwise to decrease the volume. Or use the remote control volume buttons a. Press the ▲ button to increase the volume, or the ▼ button to decrease the volume.

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 posi- tion unless you want to use the Tone Controls. Turn the Tone Switch to the On position if you want to adjust the Tone Controls.

Bass and Treble Controls 7 8

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.

Aproperly set up 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 s

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 postion. (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. Or press the corresponding source button on the remote control.

Mute Control d

Remote Only

To temporarily mute the sound of the system press the Mute Button on the RR-AT94 remote. The volume Control LED blinks when the sound is muted. Press the button again to return the sound volume to the original level.

IR Inputs and Outputs

External Remote Input p

This 3.5 mm mini-jack (labeled EXT REM IN) receives command codes from an industry- standard infrared receivers (Xantech, etc.) located in the main listening room. This feature is useful when the unit is installed in a cabinet and the front-panel sensor is blocked. Consult your authorized Rotel dealer for information on external receivers and the proper wiring of a jack to ﬁt the mini-jack receptacle.

NOTE: The IR signals from the EXTERNAL REMOTE IN jack can be relayed to source components using external IR emitters or hardwired connections from the IR OUT jacks.

IR Output [

The IR OUT jack sends IR signals received at the EXTERNAL REM IN jack to an infrared emitter, or to Rotel CD players, cassette decks, or tuners with a compatible rear panel IR connector. The allows you to use IR control features to oper- ate other components when the IR sensors on those components are blocked for obstructed by installation in a cabinet.

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 be- tween 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.

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 Monitor 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 Monitor position.

See your authorized Rotel dealer for informa- tion on IR repeater systems.

NOTE: The EXT REM IN jack located next to the IR OUTPUT jack is for use with an external IR sensor which duplicates the front panel IR sensor.
