RR 2150 Stereo RetroReceiver
Owner’s Manual
Operation
To activate Speaker EQ:
1. Look at the specification for your speakers and check for the lowest
frequency your speakers are able to reproduce.
2. Turn the SPEAKER EQ switch (FP15) to the frequency that is either
at that frequency, or one notch above it.
There is no hard rule as to which way to set this, if indeed you feel it contributes
to the sound of your system at all. A variety of conditions, including the type
of speakers in use, the room acoustics and your personal listening preferences
are all factors here. If you like the way the system sounds, choose the setting
that works best for you.
To activate Speaker EQ:
Set the SPEAKER EQ (FP15) switch to OFF.
NOTE:
Be careful about using this circuit when the bass control is
turned to its maximum boost. That is almost guaranteed to provide an
undesirable result!
Adjusting Tone Controls
The RR 2150 offers front panel tone controls that may be adjusted to suit your
listening taste. You may also take the tone controls out of the circuit completely
for “flat” operation.
To adjust the Tone controls:
1.
Press the TONE OFF button (FP1) so that the button’s blue LED is
off.
This activates the tone control circuitry.
2. Turn the BASS control knob (FP2) clockwise or counterclockwise.
You can adjust the bass cut or boost within a range of ± 6 dB. The center
detent represents the setting where bass is neither added or removed.
3. Turn the TREBLE control knob (FP5) clockwise or counter-
clockwise.
You can adjust the treble cut or boost within a range of ± 6 dB. The center
detent represents the setting where treble is neither added or removed.
To disable the Tone controls:
Press the TONE OFF button (FP1)
The button’s blue LED will light to remind you that the tone controls
are deactivated.
Balance Adjustment
The left/right balance of the RR 2150’s output may be adjusted by using the
Balance Control.
To adjust the balance:
Turn the BALANCE control knob (FP3) clockwise or counter-
clockwise.
Turning the knob clockwise emphasizes the right speaker more. Turning
the knob counterclockwise emphasizes the left speaker.
Using Headphones
You can use headphones for private listening without disturbing others or for
critical listening. Be aware that the headphone experience is not the same as
using speakers. Although some listeners prefer headphones, most prefer the
loudspeaker experience better. It’s your choice.
To listen to the RR 2150 using headphones:
1. Plug in any pair of headphones using a standard 1/4 inch stereo
headphone jack into the front panel input (F11).
For headphones used with portable devices, you may need a 3.5mm to
1/4 inch adaptor available at most electronics parts stores.
2. Use the HEADPHONE LEVEL (FP12) control to the right of the
headphone jack to set the sound level for the headphones.
3. Use the BALANCE (FP3), BASS (FP2) and TREBLE(FP5) controls to
adjust the sound output of the headphones.
NOTE:
The RR 2150’s volume control also affects headphone output.
So, if you want a truly private headphone experience, turn the Speaker
selector (FP14) off.
Recording
The RR 2150 allows you to send the signal from any input source to a record-
ing device properly connected to the rear panel Tape jacks (RP13). Note that
unlike many current audio products, the RR 2150 has a separate record output
bus so that you may listen to one source (selected with the remote control or
the front panel Source control) and record a different source. It is important
to remember this, as you may be used to always having the source you are
listening to being sent to the record output.
To record from a selected input source:
1. Prepare your recording device.
Follow the recommended procedure from the recorder manufacturer
about input settings, levels etc.
2. Select the source you want to record by using the front panel
RECORD selector (FP18).
3. Place the device in record mode to begin recording.
To monitor your recording:
Set the SOURCE selector (FP17) to your recording device.
Audio from your recording device will play through the RR 2150.
To listen to another source during recording:
Set the SOURCE selector (FP17) to the desired input source.
Audio from the selected source will play through the RR 2150. Audio to
the recording will not be affected.
