CONTACT YOUR DEALER IMMEDIATELY. Once the 865 is connected to a live mains outlet and the mains power switch is turned on, the front panel indicator will be illuminated. The indicator will be of varying color, showing that the supervising microprocessor is powered up and ready. -
Page 10: Polarity
POLARITY Please note that the 865 Integrated Amplifier conforms to the standard of Pin 2 as the positive or ”hot” pin for all analog balanced inputs and outputs. CONNECTING A BALANCED ANALOG SOURCE To realize the greatest sonic potential of your 865 Integrated Amplifier, use balanced connections whenever possible. -
Page 11: Connecting An Unbalanced Source
CONNECTING AN UNBALANCED SOURCE Although the inputs are all of the 3-pin XLR type, an unbalanced source is easily accommodated by using a special cable. This cable has an RCA phono type connector on the source end and a 3-pin connector (for an input) at the 865 Integrated Amplifier. -
Page 12: Connecting The Auxiliary Outputs
CONNECTING THE AUXILIARY OUTPUTS The auxiliary output level of the 865 Integrated Amplifier can be set to either a fixed mode suitable for use with a recording device or music distribution system; or a variable mode for use with a subwoofer or secondary amplifier. -
Page 13: Connecting The Auxiliary Outputs To Acomponent With Unbalanced Inputs
CONNECTING THE AUXILIARY OUTPUTS TO A COMPONENT WITH UNBALANCED INPUTS The 865 Integrated Amplifier’s balanced outputs can drive unbalanced inputs with a cable having an XLR connector at the source (865) end and an RCA connector at the load end. A special cable required to make this connection connects Pin 1 to the shield and Pin 2 to the RCA center conductor. -
Page 14: Polarity
POLARITY Please note that the 865 Integrated Amplifier conforms to the standard of Pin 2 as the high or ”hot” for the balanced inputs. The polarity of the 865 is such that a positive-going transition at Pin 2 will produce a positive-going transition at the ”+” loudspeaker terminal. -
Page 15: Setting The Boulderlink Switch
SETTING THE BOULDERLINK SWITCH The normal setting of the MASTER / SLAVE switch is MASTER. When using the 865 with only power amplifiers, the Boulderlink MASTER / SLAVE switch should be set to MASTER. For more information on Boulderlink, see the Boulderlink section 5-1 as indicated by the finger tab below. -
Page 16: Operation

Page 17: Input Selections
INPUT SELECTIONS To select an input, press 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. -
Page 18: Volume
VOLUME Because the precise feel of the Boulder 865’s volume control may be different than you are used to, we recommend starting the source device so that an audio signal is fed to the 865 before increasing the volume. The display will show “VOLUME INFINITE” to indicate maximum attenuation or no sound. -
Page 19: Balance
BALANCE To 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. Turning the control counterclockwise (left) will cause an indication such as “BALANCE R -2.0dB <... -
Page 20: Mute
After several seconds of not changing the balance, the display will return to the “VOLUME...” indication. You may also return to controlling volume by again pressing the BALANCE pushbutton. The balance resolution is the same as for the volume control, 0.5 dB steps. WARNING: If the input is programmed to be in “THEATER MODE,”... -
Page 21: Display
DISPLAY The display brightness may be set to any of four brightness levels. To change the brightness level, press the DISPLAY pushbutton. “DISPLAY 100%” will show in the display. Rotate the center control until the desired brightness is obtained such as “DISPLAY 50%.” The number in the display is the relative brightness. -
Page 22: Remote Control
REM OTE CONT ROL BATTERIES A standard small flat-blade screwdriver is required to install the three AAA batteries. To install batteries in the remote control, it is necessary to separate the two sections. WARNING: When opened, the pushbutton balls will be loose and care must be taken to properly retain them. -
Page 23: Source Selection
SOURCE SELECTION To select an input (source) 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. You will now be listening to your desired input. -
Page 24: Programming
PROGRAMMI NG 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 Theater Mode. - Page 25 If you chose to assign a name, then “1 INPUT ONE” will be shown in the bottom display row with a blinking cursor before 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.

Page 37: Boulderlink Messages
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 off to protect the speakers from damage. - Page 38 “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 recognized by the master.
