MAKING THE CONNECTION

SYSTEM CONNECTIONS

It's tempting to plug in your new Preamplifier Tuner and have great sound pour out. Before you do that, take
a few minutes to plan out how you want the Preamplifier Tuner to fit into your audio system. Keep the follow­ing suggestions in mind:

··

List all components in your system and indicate which jacks of the Preamplifier Tuner each compo­nent will be connected to. Your Preamplifier Tuner has six sets of inputs. It is convenient to connect a
DVD player to the input labeled DVD or a VCR to the input labeled V1 or TAPE, etc. However, your
equipment may differ from the labeling on the back of your Preamplifier Tuner. In most cases you can
connect any type of source to any input. For example, if you have a satellite receiver you can connect
it to V2. You can also reprogram the source name that will appear on your Preamplifier Tuner's front
panel.

··

Also note the length of the cable for each component's connection and describe how it should be
routed. You may want to label each cable with a name or number at both ends. Use high quality con­nections to maintain high quality audio.

··

Think about the type and length of cable you need and obstacles in the cable's path (doorways, fur­niture, walkways, etc.). To decide which ones are right for you talk to your dealer about the various
cable products that are available.

··

For safety, keep all cables out of high traffic areas (hallways or doorways) and away from equip­ment that radiates power, including amplifiers, power cords, heaters, etc.

··

If you might expand your audio system later, keep these ideas in mind as you plan current cable runs.

··

To provide the best tuner reception, make sure the antenna is at least 6 ft away from the
Preamplifier Tuner and any other equipment that may produce high frequency interference such as
Personal computers, CD players, halogen lamps, etc.

SOURCE CONNECTIONS

To connect your analog sources to your Preamplifier Tuner, take a look at the back panel. You will notice that
the RCA-type audio input and output connectors are identified by colors, RED for right channel and WHITE
for the left channel audio.

Audio source Input - To connect a source such as a CD player

to the Preamplifier
outputs from the CD player. Attach one end of the audio interconnect
cable to the left (White) audio output on the CD player, then attach
the other end to the left (white) CD audio input on the Preamplifier

ACCESSORIES

FIVE POSITION PHOENIX CONNECTOR

Control I/O - The five pin phoenix connector can be used when interfacing other equipment with the

Reference 5 S2. Equipment such as CK1.2 Keypads, an external amplifier, or devices that require a +12VDC
trigger.

+12VDC - +12VDC power supply for keypad or IR sensor
Ground - Common ground
RS-232 Xmit - RS-232 one-way transmit out
Data In - Infrared Data/Signal input
CTRL Out - 12VDC programmable trigger out

Note - The entire control output is capable of suppling a maximum
that the device(s) being connected to the control require 200 mA or less current.

of 12VDC @ 200 mA. Check to see

KEYPAD or IR SENSOR CONNECTION

To connect a CK1.2 Keypad to the Reference 5 S2, simply run a straight through CAT5 wire from the keypad
location to the Reference 5 S2. The keypad end of the CAT5 can be terminated into RJ-45. The keypad end
can also be terminated into the five position phoenix on the back of the keypad. Terminate the Reference 5
S2 end of the CAT5 cable manually into the phoenix connector. You can also order a RJ-45 to phoenix adap­tor part number 21419 from B&K. See diagram below. If an IR sensor will be used, use the +12VDC GND
and IR Data to the IR sensor. RS-232 keypad status feedback is not functional on a Reference 5 S2.

Note: If an IR sensor is
going to be used, only

P/N - 21419

+12VDC, GND and IR DATA
need to be connected

AMPLIFIER CONTROL TRIGGER

If it is desired to use an amplifier control trigger to remotely control an external amp, then the +12VDC and
GROUND should be terminated into an 1/8” (3.5mm) mono mini jack. Plug the mini jack into the amplifier
Control IN that is going to be controlled. If a keypad is also connected to the Reference 5 S2, the amplifier
control trigger can be connected in parallel with the control trigger. See diagram below.

UNIT OPERATION

The following pages outline the normal day-to-day operation of your Preamplifier Tuner. The Reference 5 S2
can be controlled either from the supplied IR remote controller or directly from the front panel buttons.

POWER ON/OFF

The master power switch located on the front panel of your Preamplifier Tuner must be “ON” (pressed in) for
the Preamplifier Tuner to operate. When this switch is OFF (pressed out) all power is removed from your
Preamplifier Tuner. This will prevent turning it back on with the remote control or keypad. For normal day to
day operation, leave the master power switch in the ON position. Use the ON/STANDBY function for daily
power on and off. This will allow the Preamplifier Tuner to be turned on and off from the remote control or
keypad.

Whenever turning on the master power switch, you must wait approximately 10 seconds while your
Preamplifier Tuner restores its internal memory and initialize system parameters. You may want to turn off the
master power switch only when your Preamplifier Tuner will be idle for extended periods of time or during
periods of power line fluctuations. Your Preamplifier Tuner will not lose its memory while the master power
switch is off.

ON/STANDBY

For normal day to day operation, you will put your Preamplifier Tuner in STANDBY when not in use. Standby
mode keeps a bare minimum of functions running in order to allow a remote control or keypad to quickly
power up the unit. Note that the front panel ON/STANDBY button is lit while your Preamplifier Tuner is in
standby and is not lit when your Preamplifier Tuner is operating. The front panel alphanumeric display is off
during standby. Also note that the supplied IR remote's POWER button is a toggle. The remote control or key­pad additionally has discrete power OFF and ON buttons.

9

ADJUSTING VOLUME

The front panel “VOLUME” control knob is known as an encoder. This is because it also has the ability to
control functions other than volume. Other functions include, BASS, TREBLE, BALANCE, etc. Normally the
encoder knob will control volume. Volume can also be adjusted using the remote control or a keypad. The
volume can be adjusted up or down.

CHOOSING A SOURCE

The Reference 5 S2 has the ability to select any of the eight possible source inputs. The names of the
sources are default labeled for V1, V2,
changed using either the BKcSuite setup software or the Reference 5 S2 front panel. FM and AM cannot be
changed. Even though the inputs are specifically labeled for source names, it does not matter what source is
connected to each input. The label (name) of the input can be changed (See page 13 for label change pro­cedure). Asource can be selected from the remote control or a keypad if it is connected. A source can also
be selected from the front panel using the source button. The source button will step through each of the
source inputs.

If a recording device (such as a tape recorder) will be used to record audio material, it should be connected
to the

Reference 5 S2.

TAPE OUT RCA connectors. The TAPE OUT will output only the audio source that the user has been

TV, DVD, CD, FM, AM and TAPE. These labels can be adjusted and

ADJUSTING BALANCE

The audio balance can be adjusted left to right or visa versa using the BAL (L) or BAL (R) on the remote
control. The balance adjustment will adjust the gain per each side (left or right) of the stereo output.

UNIT OPERATION

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

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 tun­ing 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

From the factory, the advanced menu is hidden from user access. To un-hide the advanced menu,
simultaneously press the UP, DOWN and ON/STANDBY buttons. “ADVANCED VISIBLE” will flash on the

screen indicating the advanced menu is unhidden. If the memory or front panel has been locked, this button
press sequence will unlock the memory.

Maximum Volume Level

The maximum volume level can be limited on the Reference 5 S2. The absolute maximum volume level
is +8dB. Line level volume level is 0dB (zero).

Product ID (Code-Set)

The product ID (IR code set) can be adjusted if operation with other B&K is gear is required. The default ID
is 002 (zero zero two). The Reference 5 S2 can be assigned to any ID (B&K code-set) between 001 and

016. This allows sixteen different Reference 5 S2’s to operate independently using different remote controls.
This feature is typically useful if multiple Reference 5 S2’s are used in the same system (whole house audio
systems). NOTE: If the code set of the preamplifier is changed, you will need a learning or programmable
remote control to operate the unit via IR. B&K offers the SR10.1 programming remote, the CK1.2 Keypad or
MZ-128 remote if different code-set operation is required. For more information on code-sets, see the B&K

CT610/310/600 Mulit-Zone Receiver User Manual.

Power On Titles

When the Reference 5 S2 powers up it will flash two lines of power on titles. These lines can be customized
for your own preferences. Each line for power on titles contains 16 customizable characters.

Control Setup (+12VDC trigger)

The single +12VDC control trigger can be programmed to be on or off depending on the dif
the Preamplifier Tuner is used for. The control trigger can be setup for each input of the Reference 5 S2.
Each input has the following options:

OFF = When the input is selected, the control output is off.
ON = When the input is selected, the control output is on.
PHONES = (Headphones) When the input is selected and headphone mode is selected, the

control will turn off, therefore turning off an external amplifier.

REMOTE = When the input is selected, IR will pass-through the 12VDC control out. IR will pass-

through either from a keyp
connected to the +12VDC output and the common ground.

RS-232 = When the input is selected, the control output can be controlled with RS-232.

Typically, the +12VDC trigger will be used for controlling an external amplifier. When the 12 volts is on, the
amp is on, when the 12 volts is off, the amp is off. The amplifier must be equipped with a control trigger. All

amps are equipped with control triggers. The Preamplifier has the 12VDC trigger default set for head-

Security

The Reference 5 S2 has the capability to lock the front panel buttons, turn off the front panel IR receiver, and
lock the memory so it cannot be changed. If the front panel IR receiver is turned off, it will also disable a key­pad or IR sensor if a keypad or IR sensor is being used.

Selection
Memory Lock - YES or NO = Locks all personal settings from being changed.
Front Lock - YES or NO = Locks all front panel operation.
IR Lock - YES or NO = Disables all IR communication to the preamplifier

Options Definitions

RS-232

The main RJ-45 jack can be enabled or disabled. The baud rate can be adjusted. For best operation the
baud rate should be left at 9600. The Echo/Update feature can be toggled on or off. Echo and Update will
either echo an RS-232 message received or send out an update message indicating the unit has made a
change. The transmit and receive ID’s can be adjusted for operating with RS-232 controllers. B&K provides
all RS-232 serial codes for use with RS-232 controllers. These documents in .pdf format can be found on our
