FE A TURES The Reference 50 Series2 preamplifier is a versatile Audio/Video control center . This preamplifier is designed to sound sensational and be an attractive, easy-to-use addition to your Audio/Video system. Video T ranscoding - Allows composite and S-Video input s to source the composite, S-Video and component video outputs.
AUDIO / VIDEO OVER VIEW Definitions Sources - A source is considered to be any device that can be connected to the audio/video receiver or processor and transmit a signal that can be seen or heard. T ypical sources include DVD players, satellite boxes, CD players, etc.
Analog vs. Digit al Audio - This refers to the method used to place audio information on the source material and how they are delivered to your preamplifier from the source. Analog signals exactly represent the sound you will hear through a continuously varying voltage.
Dolby Digit al Surround EX - Dolby® Digital Surround EX™ provides a third surround channel on Dolby Digital movie sound tracks. The third surround channel can be decoded at the cinema's or home viewer's option for playback over surround speakers located behind the seating area.
DTS 5.1 (Digit al Theater Systems) - DTS is a multi-channel digital audio compression format transmitted over optical digital or coaxial digit al connections.
waves is a desirable effect to a point. Dif ferent locations in the room will have waves that collide with one another . This collision can cause a superposition (addition or subtraction) of the audible wavelength. In either case, these locations are referred to as nodes.

QUICK ST ART CONSIDERA TIONS Y our B & K preamplifier is pre-programmed for ease of operation right out of the box. In general, there is minimal setup required to start using your new A/V preamplifier .
SOURCE CONNECTIONS Y our preamplifier supports several A/V input and output formats. In most cases only one audio and one video connection is needed for each source device. Shown below are the available options: Analog audio (Stereo): lef t and right.
VIDEO MONIT OR CONNECTION There are many types of video monitors that can be used with your B & K system. Some popular video monitors are televisions, plasma screens, LCD screens and projectors. The B & K A/V processor has video and audio switching capability .
SURROUND OUTPUT CONNECTIONS Y our B & K preamplifier has two types of surround outputs: balanced (XLR) outputs and coaxial (RCA) outputs. Both types of output s connect from the preamplifier directly to the amplifier in the system. Either type of connection can be used when connecting to the external amplifier .
6.1 / 5.1 Balanced Output Connections For use in a 6.1 or 6.0 audio setup, refer to the diagram below . We recommend the 6th speaker be connected to the surround back left channel of the surround preamplifier . However , either the back left or back right output will operate correctly when the system is configured for use with one back speaker .
R CA Surround Output / Subwoofer Connection The Reference 50 Series2 supplies 7.1 RCA coaxial surround output s. These surround output s can be used to connect an external amplifier or the subwoofer to the preamplifier . T o connect seven audio channels, connect seven coaxial audio cables between the surround outputs and the amplifier input s.
18 HARDW ARE CONNEC TIONS P ASS THROUGH / RECORD LOOP CONNECTIONS The B & K preamplifier has a few options for record/pass through output s. There is a Zone A optical digital output, a Zone A coaxial digital output and a Zone B coaxial digital output.
+12VDC Control Connection If the +12VDC trigger is going to be used, it should be connected as shown right. An external amplifier is being used for this example, however the external device could be any device that employs a control trigger circuit. The plug must be wired as tip (+) and the sleeve (-).

KEYP AD CONNECTION DESCRIPTION T o connect a CK1.2 Keypad to the Reference 50 Series2, run a straight through Category 5 (CA T5) cable from the keypad location to the RS-232 jack on the preamplifier back p anel. T erminate both ends of the CA T5 cable into RJ-45 using the T568B st andard.
SETTING UP THE SYSTEM The setup of the preamplifier will require navigation through the menu system. T he system menu will display on the front panel as well as an On-Screen Menu format.
MAIN MENU SELECTIONS The main menu descriptions are accompanied by the On Screen Menu layout below . In some cases, the front panel will display a slightly abbreviated version of what the On Screen Menu shows due to character space limit ations.
SYSTEM SETUP 1. Setup Speakers This menu configures the preamplifier for the number of speakers, speaker size, and location of the speakers in the room. It also contains room equalization options that can optimize the sound for a p articular room. The overall sound quality of your system will depend upon how the parameters of this menu are setup.
SETUP SPEAKERS 1. Speaker Size The speaker setup menu defines how many speakers are installed in the system, the relative size of the speakers, and their location in the room. This is the most important setup procedure that will be performed. The preamplifier comes from the factory setup for 7 small speakers and a subwoofer .
2. Setup Speaker Location Ideally the speakers should be positioned at an equal distance from the listening position. However , physical limitations usually require placing the speakers in other than optimum locations. The surround processor contains a means to electronically move each speaker’s location.
LFE (0.1) channel level - Usually this will be set to 0.0 dB (default). However , if there is no subwoofer you may wish to reduce the Low Frequency Effect s (LFE) channel to lessen its contribution to the bass going to the remaining large speakers.
The situation is different for large low-frequency peaks. These peaks are what tend to shake the knick-knacks off the shelves and result in an overall tubby sound to the bass. Fortunately , this CAN be remedied electroni- cally…and without drastically altering the characteristic sound of your speakers.
SETUP INPUTS This menu allows you to tell your preamplifier how you would like each input to operate. Y ou may repeat the following steps for each input by changing input s on the top line of the menu or with the supplied remote control. 1. Default Audio Modes - There are two major categories of audio, 2-channel and 5.
6. Input name - Five characters maximum. From the factory , the preamplifier will display source names that match those printed on the back of the preamplifier and on the supplied SR10.1 remote. These names can be changed to match the type of source that is being used.
SETUP DISPLA YS Front Panel - Describes the possible selections for the brightness of the front panel display . Bright, medium, dim. OSD Color - Set the preferred color for the OSD menu. Default setting is blue. Select from Blue, Purple, Pink, Aqua, Lilac, Y ellow , Red, or Green.
32 MENU SYSTEM SETUP UNIT INFORMA TION Unit information provides hardware information about your preamplifier . Unit - The model of the preamplifier sof tware - The sof tware version currently running in the hardware. S/N - Serial Number BKC-DIP - B & K Components Device Interface Protocol version.
Descriptions of each option of the advanced system setup menu are as follows: Zone ‘1’ Home Theater - Allows adjustments for the main home theater zone. Set the max volume, zone ID, Record loop and surround mode options. Power On Titles - Customize power on titles for customized personal greetings.
Power on Titles Personal power on greeting can be programmed to display on your B & K ’s front panel display . Both power on lines contain 16 alphanumeric characters. Power on titles will appear when the preamplifier is taken out of S tandby . Have fun with your power on titles, and try to WOW everyone.
35 AD V ANCED MENU SYSTEM SETUP DSP Usage This screen monitors the amount of processing power being used. Expressed in MIPS (Millions of Instructions per Second) Security Options In the security menu, the user can protect the preamplifier from accidental changes to unit settings or reprogramming.
RS-232 Control Port The RS-232 port refers to the main RJ-45 connection located on the preamplifier's back panel. The RJ-45 contains connections for transmission and reception of RS-232 data. See pin-out at right. The RJ-45 also supports power supply and IR input for CK1.
Plug and Play Timing Setup Plug and play timing pertains to the internal delays associated with the Plug n Play audio detection system. DO NOT ADJUST THESE P ARAMETERS UNLESS THERE IS A PROBLEM HEARING AUDIO Y our preamplifier has default audio Plug n Play settings that work with the majority of A/V sources and digital audio bitsreams.
Zone 2 ‘B’ Second Zone Level Control - V ariable or fixed. The second zone can be configured for a fixed volume level if external volume control is desired. Max Level - Set the maximum volume for the second zone. This can be used to protect your speakers or ears from inadvertent excessive volume.
SR10.1 REMOTE CONTROL OPERA TION Y our B & K preamplifier is supplied with a state-of-the-art remote control. The SR10.1 is a computer programmable learning remote. It can be programmed to control any or all of the components in your system using IR.
UNIT OPERA TION The following pages outline the normal day-to-day operation of your preamplifier from the supplied SR10.1 remote control. All unit functions can also be directly controlled from the front panel. The SR10.1 remote is capable of controlling both the B & K preamplifier plus other source gear in your system.

The first t able shows how the front panel will display multi- channel digital bit streams. The second table shows how the front p anel will display two channel audio types.
AUDIO MODES & SPEAKER SELECTIONS B & K incorporates a state-of-the-art sof tware and hardware system that will prioritize the incoming audio signals (Plug n Play) and accordingly select the ap.
Material correctly mixed for Dolby Pro Logic contains no bass information in the surround channels and there- fore, Dolby requires that no surround bass is mixed to the subwoofer when you have small surrounds. However , many video game systems do end up with bass information in the surrounds.
Speaker Selections The table below shows how your preamplifier will route audio information to the speaker channels depending on audio modes and speaker selection combinations. Audio information will not be lost in any speaker selec- tion. The information for the missing speakers is mixed to other active speakers.
EQUALIZA TION SETTINGS AND ADJUSTMENTS The preamplifier provides 3 ways to modify the frequency response (equalization) for particular listening situa- tions. These equalization are in addition to the room equalization and room resonance adjustment s made in the speaker setup menu.
