ADJUSTING BASS, TREBLE AND LOUDNESS
Bass, treble and loudness can be adjusted using the remote control supplied or the front panel. To adjust the
level using the front panel, press the LEVEL
button to cycle through the selections. BASS increases or
decreases the low frequency content in 2 dB increments with a range of +/- 12 dB. Treble increases or
decreases the high frequency content in 2 dB increments with a range of +/- 12 dB. Loudness may be used
to further shape the audio signal for increased clarity and intelligibility at low listening levels. When the
desired selection is displayed, rotate the encoder right or left to adjust the level up or down. The loudness
can be adjusted using either the remote control or the front panel button.
TUNER OPERATION
All TUNER operations require the Preamplifier Tuner's source be set to TUNER.
Manual Tuning -
press TUNE + or TUNE - on the remote control to tune the frequency UP or DOWN in
single 10 kHz steps for AM or 200 kHz steps for FM. (9 kHz and 100 kHz steps for European version.) If tun-
ing from the front panel is desired, use the UP and DOWN arrow buttons to step through the frequencies.
When the tuner is selected.
Direct Frequency Entry Tuning -
To directly recall a tuner frequency, press the TUNER button, then
enter the frequency of the station. However, once
any
tuner operation (TUNER, BAND, AM, FM or TUNE+/-)
is performed, you may directly enter a frequency from the remote control's numeric keypad. The Reference 5
S2 will only “look” for a direct frequency entry for three seconds after one of the tuner operation commands is
received by the unit.
Example - button press steps for directly entering the radio station for 103.3 FM = FM - 1 - 0 - 3 - 3
Seek Tuning -
Holding the remote TUNE +/- button will cause the tuner to SEEK (tune up or down auto-
matically stopping on strong stations). Once the tuner has started seeking you can release the button. In
strong signal areas the tuner may stop one step above or below the true frequency. Unless you are sure of
the station's frequency, check to see that the signal might be better one step above or below the frequency
that SEEK has found. In weak signal areas the tuner may continue to seek all the way to the end of the band.
To stop this simply press the opposite TUNE +/- button. Seeking can also be done from the front panel by
holding the UP or DOWN arrows until the tuner starts to seek.
Remote Control Commands
BAND -
toggles between the AM and FM frequency bands.
AM -
selects and allows tuning of the AM frequency band.
FM -
selects and allows tuning of the FM frequency band.
ST/M -
allows selecting of Stereo and Mono in the FM frequency band. Setting / Programming a chan-
nel to Stereo will play the channel in stereo if it is broadcast in stereo. Setting/Programming a channel
to Mono will force the channel to mono regardless of the broadcast. Use mono to reduce background
noise on weak channels.
HEADPHONE MODE
Headphone Mode allows you to operate your Preamplifier Tuner using a set of headphones. The headphone
jack uses a 1/4” (6.3mm) stereo jack. To select the headphone mode, press the MODE button on the remote
control. MODE will toggle between Headphone ON and Headphone OFF. When in headphone mode, the
CONTROL OUT is set to off. This feature allows your Preamplifier Tuner to turn off external amplifiers or pow-
ered sub woofers with compatible 12VDC CONTROL inputs. Headphone mode can also be set up using a
preset. See
