Connecting Your RR 2150
External Amplifier Connections
You can use a separate, external power amplifier either as a substitute for the
RR2150’s internal amp or to supplement the internal amp when adding addi- tional speakers in a different area of your home. Remember that the RR 2150 is not designed for “dual source” operation. (Although the “Tape” outputs may be used for that purpose if they are not connected to a recorder.) An additional amplifier will only amplify the source you select with the RR 2150’s input selec- tor (FP17 and RC11 for front panel and remote control respectively).
As with any component that is connected to the RR 2150, always make sure that both the RR 2150 and the additional amplifier are OFF or disconnected from any AC power source when making these connections. A misstep here could result in severe damage to your amplifier and/or loudspeakers.
There are a number of options available to connect an external amplifier:
Option 1:
Using an external amplifier only.
Remove the pre-out/main-in U-shaped jumpers. Connect the RR 2150’s pre- amplifier outputs (RP17) to the external amplifier’s inputs. Next, connect your speakers to the external amplifier.
This option lets you control the volume produced by any speakers connected to the new amplifier with the RR 2150’s volume control.
Option 2:
Using an external amplifier AND the RR 2150’s internal amplifier for two sets of speakers fed with the same source and at the same relative volume level.
Remove the pre-out/main-in U-shaped jumpers. Using a pair of shielded a “Y” interconnects, connect the RR 2150’s left channel preamp output to both the RR 2150’s main amplifier inputs and to the left channel inputs of the new amplifier. Repeat the step above for the right channel.
This option lets you control the volume produced by any speakers connected to the new amplifier with the RR 2150’s volume control.
Option 3:
Using the RR 2150’s internal amplifier and external amplifier for two sets of speakers fed with the same source, but with the ability to turn the second pair of speakers on an off from the front panel.
Do not remove the pre-out/main-in jumpers. Connect the RR 2150’s External Loop outputs (RP14) to the external amplifier’s inputs. (This, of course, pre- sumes that you are not using the External Loop connections.) Next, connect the speakers to the external amplifier. You will still be able to connect speakers to the RR 2150’s amplifier.
The RR 2150’s volume control sets the relative level for both pairs of speakers. You may turn the speakers connected to the external amplifier on or off by pressing the External Loop switch on the front panel.
Note: This option is best suited for a custom installation and may require a separate volume control for the speakers attached to the external amplifier.
Option 4:
Using an external amplifier to send a second source to a second set of speakers.
Do not remove the pre-out/main-in jumpers. Connect the RR 2150’s Tape outputs (RP13) to the external amplifier’s inputs. (This, of course, assumes you are not using the Tape connections.) Next, connect the speakers to the external amplifier.
Use the RR 2150’s volume control to adjust the level to the speakers connected to the RR 2150.
The input for the source fed to the external amplifier and the speakers connected to it is selected with the front panel Record Selector (FP 18). As the output to the Tape Outputs is fixed, we strongly advise that you either use an amplifier with built-in volume control for this application, or that an optional speaker-level volume control be installed between the outputs of the external amplifier and the speakers. Be certain that the volume control is capable of handling the power output from your external amplifier.
Note: As with Option 3, this is best suited for a custom installation to make certain that all external components are properly matched for safe operation.
12 Volt Trigger
The RR 2150 has one 12 volt Trigger output that output offers a 12 volt DC signal that can be used to control compatible external components such as amplifiers, blinds and projection screens.
To control an external device such as an Outlaw power amplifier with the RR 2150, connect the Trigger Output (RP5) on the rear panel to the matching “Trigger” or “Control” input on the external component.
Once the two units are connected, the external component will turn on when the RR 2150 is on, and off when the RR 2150 is turned off.
AC power connection
Insert the supplied power cord into the AC input socket (RP20), and then con- nect it to a non-switched AC outlet. If a power conditioner or other device is used between the RR 2150 and the AC power source it is your responsibility to make certain that the external device is capable of handling the power drawn by the RR 2150. Use of external power products not compatible with the RR 2150 may create a safety hazard.
It is important use the supplied power cord, not a standard IEC 3-prong (grounded) power cord. If the power cord is replaced, by certain to use one with identical configuration and capacity.
CAUTION: Before you plug the power cord into an AC wall outlet, confirm that you’ve made all connections to the RR2150 first.
WARNING: Never disconnect the power cord at the RR 2150 end while the other end is still plugged into an AC outlet. This may cause an electric shock. Always connect power by plugging into the AC outlet last and disconnect by unplugging from the AC outlet first.
