INPUT SELECTIONS T o select an input, pr ess one of the pushbuttons labeled ONE, TWO, THREE or FOUR. The respective input will be shown in the display and that signal will be routed to both the loudspeaker and auxiliary outputs. For example, if input ONE is chosen, “1. INPUT ONE” will show in the display . NOTE : There will be a delay when swit[...]

VOLUME Because the precise feel of the Boulder 865’s volume control may be differ ent than you ar e used to, we recommend starting the source device so that an audio signal is fed to the 865 befor e increasing the volume. The display will show “VOLUME INFINITE” to indicate maximum attenuation or no sound. By placing a finger at the edge of th[...]

BALANCE T o change the level balance, press the BALANCE pushbutton. “BALANCE CENTERED” will show in the display . Now , rotating the control will change the balance instead of the volume for as long as “BALANCE...” is displayed. T urning the control counterclockwise (left) will cause an indication such as “BALANCE R -2.0dB < “ in the[...]

After several seconds of not changing the balance, the display will return to the “VOLUME...” indication. Y ou may also return to controlling volume by again pressing the BALANCE pushbutton. The balance r esolution is the same as for the volume control, 0.5 dB steps. W ARNING: If the input is programmed to be in “THEA TER MODE,” then the ba[...]

DISPLA Y The display brightness may be set to any of four brightness levels. T o change the brightness level, pr ess the DISPLA Y pushbutton. “DISPLA Y 100%” will show in the display . Rotate the center contr ol until the desired brightness is obtained such as “DISPLA Y 50%.” The number in the display is the r elative brightness. After seve[...]

REMOTE CONTROL BA TTERIES A standard small flat-blade screwdriver is requir ed to install the three AAA batteries. T o install batteries in the r emote contr ol, it is necessary to separate the two sections. W ARNING: When opened, the pushbutton balls will be loose and care must be taken to properly retain them. It is recommended to lay the remote [...]

SOURCE SELECTION T o select an input (sour ce) press the button on the left side of the remote control whose number corresponds to the input you wish to listen to, and it will show in the display . Y ou will now be listening to your desir ed input. VOLUME, BALANCE and MUTE T o increase the volume, press the button on the right side marked with an u[...]

PROGRAMMING While it is not necessary to ever use any programming functions, you will find they maximize the enjoyment of your Boulder 865 Integrated Amplifier . Each input has several programmable features associated with it. These include assigning an alphanumeric name of your choosing, setting an individual start volume and balance, and setting [...]

If you chose to assign a name, then “1 INPUT ONE” will be shown in the bottom display r ow with a blinking cursor befor e the name’s first character . Rotate the control until the desired character appears. Press the same input source number to accept the displayed character and go to the next character . Continue in this manner until all 17 [...]

INPUT LEVEL CALIBRA TION Pressing the same input source number will make “INPUT LEVEL 0.0dB” show in the bottom display row .

BOULDERLINK Boulderlink is a means of interconnecting most Boulder products so that their micr oprocessors can talk to each other and pass important information. Among the key features, Boulderlink allows sequential initiation of power amplifiers and other products when the 865 Integrated Amplifier is turned on. Power amplifiers can send messages t[...]

5-2 BOULDER LINK CONNECTING 800 SERIES TO 1000 OR 2000 SERIES WITH BOULDERLINK If you ar e using the 865 Integrated Amplifier with certain other Boulder pr oducts, a Boulder Link Adapter Box (BLAB) might be r equired to make the connection. Although the connectors ar e mechanically dif ferent between the series, they are electrically the same, thus[...]

SETTING BOULDERLINK SWITCHES Every Boulderlink system must have one “MASTER” component, and only one component can be set to MASTER. Usually this is the preamplifier or CD Player . Power amplifiers and other products not having a MASTER/SLA VE switch can never be “MASTER.” On the 865, the Boulderlink MASTER/SLA VE switch will normally be se[...]

POWER UP VIA BOULDERLINK W ith each component connected together with a Boulderlink cable, and individually connected to the AC mains, pr essing the 865’s ST ANDBY pushbutton will initiate the turn-on sequence of all components. The first time a “MASTER” 865 is powered up, it will search for any “slave” units connected to it. As the Maste[...]

5-5 BOULDER LINK An 865 set to “SLA VE,” will display “THIS UNIT SLA VE #______.” If there is no component set to “MASTER,” the 865 will display “THERE IS NO MASTER!” In this case, the 865’s MASTER/SLA VE switch should be set to MASTER. It may take up to 30 seconds for the 865 to recognize the switch change.[...]

BOULDERLINK MESSAGES Each component in the system can send a message to the 865 which is then shown on its display . This is particularly helpful in confirming the operating status of each power amplifier in a multiple amplifier system. “AMPLIFIER 1 ERROR” means that an internal power supply has failed and the amplifier has turned itself of f t[...]

“UNIT 1 IS OFFLINE” means that the slave is no longer responding via Boulderlink. Its Boulderlink cable may have become disconnected, or the AC mains power has been disconnected. “UNIT 1 IS ONLINE” means that the slave is now responding via Boulderlink in a normal manner and has been r ecognized by the master . BOULDER LINK 5-7[...]
