4 CONNECTION OVERVIEW The following is an overview of connections found on the Reference 70. Further information can be found later in the quick guide or in the Reference 70 manual. This guide should only be used for reference only. It is recommended an authorized B&K installer or dealer is contacted for integration of the preamplifier in advanced installations.
VIDEO INPUT CONNECTIONS Composite Source S-Video Source Component Source HDMI Source Video Input Connection - HDMI The HDMI connection carries both audio and video, although it is possible on the B&K product to only output one or the other (please see the menu structure for further information). To connect an HDMI video source to the B&K, connect the HDMI cable to the HDMI output on the source piece. Then connect the other end of the cable into the corresponding HDMI input on the preamplifier.
6 AUDIO INPUT CONNECTIONS Analog Source Coaxial Digital Source Optical Digital Source HDMI Source Audio Input Connection - HDMI The HDMI connection carries both audio and video, although it is possible on the B&K product to only output one or the other (please see the menu structure for further information). To connect an HDMI audio source to the B&K, connect the HDMI cable to the HDMI output on the source piece.
AUDIO/VIDEO OUTPUT Audio Output Connection - Unbalanced The Reference 70 supplies 7.1 RCA surround outputs. These surround outputs can be used to connect to an external amplifier and/or the subwoofer to the preamplifier. To connect seven amplifier channels, connect seven RCA audio cables between the surround outputs and the amplifier inputs. Be sure to match the appropriate preamp output to the speakers location in the room.
8 CONFIGURATION AND CONTROL There are a few different ways to achieve control and configuration of the Reference 70. Using the component video or HDMI output on the Reference 70 you can get the on-screen menu GUI to an HD monitor. Ethernet or RS-232 communication can also be used using a serial or ethernet control device or a PC. Some restrictions may apply. Please see the full manual or the B&K website for further information.
