AC Power and Control

AC Power Input

The RA-1070 uses a moderate amount of power. However there are two auxiliary power outlets on the back of the unit, which can be used to supply up to 200 watts of power for other components. Consequently, the RA-1070 should be plugged directly into a 2-pin po- larized wall outlet. Avoid the use of extension cords. A heavy duty multi-tap power outlet strip may be used if it (and the wall outlet) is rated to handle the current demanded by the components connected to it.

NOTE: Do not connect the power cord for a power amplifier to the auxiliary power outlets on the RA-1070. Power amplifiers often draw more power than these outlets can provide. The auxiliary power outlets should be used only to power source componets, such as CD players or tuners.

Your RA-1070 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 115 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC line configuration is noted on a decal on the left side.

NOTE: Should you move your RA-1070 amplifier to another country, it is possible to reconfigure it for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RA-1070 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information.

If you are going to be away from home for an extended period of time such as a month- long vacation, it is a sensible precaution to unplug your amplifier (as well as other au- dio and video components) while you are away.

Power Switch and Remote Power Button

The Power switch is located on the left side of the front panel. When it is pressed the RA-1070 is turned on and the front panel displays and indicators are illuminated. When the front panel Power button is in the “on” position, the RR-969 Power button can be used to put the RA-1070 into standby mode and return it to regular power mode. When the RA-1070 is in standby mode the front panel display is turned off and amplifer circuits go into low power mode.

NOTE: The RA-1070 will be turned on and in the normal operating mode as soon as it is connected to the AC outlet. Be sure to set the Volume control to the minimum (full counterclockwise) position before con- necting the power cord.

Auxiliary Power Outputs

(North American version only)

The RA-1070 has two switched outlets on the back panel. Power is available from these outlets when the RA-1070 is in regular power mode. Power to these outlets is turned off when the RA-1070 is in Standby mode. These outlets can provide up to a total of 200 watts. They are appropriate for sup- plying power to signal sources, such as CD players, tuners, or tape decks. They should not be used for power amplifiers. Connecting components that will draw more than 200 watts to these outputs could damage the Power switch in the RA-1070.

Input Signal Connections

[See Figure 3.]

The RA-1070 has conventional RCA-type con- nectors for all inputs.

NOTE: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections.

Phono Input and

Ground Connection

Plug the cable from the turntable into the appropriate left and right phono inputs. If the turntable has a “ground” wire connect it to the screw terminal to the left of the Phono in- puts. It will help prevent hum and noise.

Line Level Inputs

The CD, DVD/Video, Tuner, and Aux inputs of the RA-1070 are “line level” inputs. These are for connecting components such as CD players, Hi Fi or NICAM Stereo video cas- sette recorders, tuners , Laser Disc players or the analog output from a CD ROM drive.

The Left and Right channels are clearly labeled and should be connected to the correspond- ing channels of the source component. The Left RCA connectors are white, the Right con- nectors are red. Use high quality RCA cables for connecting input source components to the RA-1070. Ask your authorized Rotel dealer for advice about cables.

Recorder Connections

[See Figure 3.]

The Tape 1 and Tape 2 inputs and outputs can be connected to any record/playback device that accepts standard line level analog input and output signals. Typically that will be a con- ventional tape recorder.

When connecting a recorder to the RA-1070, remember that the outputs of the recorder must be connected to the tape inputs of the RA-1070. Similarly the tape outputs of the RA-1070 must be connected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associ- ated components. Use high quality connect- ing cables to prevent loss of sound quality.
