User manual HEED OBELISK SI

[. . . ] Power Sources -- The unit should be connected to a power supply only of the type described in the operating instructions or as marked on the unit. Power-Cord Protection -- Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the unit. Lightning -- For added protection during a lightning storm, or when left unattended and unused for long periods of time, unplug the unit from the wall outlet. This will prevent damage to the product due to lightning and power-line surges. Object and Liquid Entry -- Care should be taken so that objects do not fall into and liquids are not spilled into the inside of the unit. [. . . ] Should any problems be experienced which are not covered here, contact your local dealer. If you are unable to do so, or problems persist, however, do not hesitate to contact our distributor/trade partner in your country (see our website > www. heedaudio. com > "worldwide distributors" for details), or us directly at Heed Audio . . . we're here for you! placement In common with all high-quality audiophile equipment, the Obelisk Si performs optimally when positioned on its own individual mounting surface, ideally a light rigid structure. There are many proprietary purpose-built examples readily available from all better dealers. Always allow adequate ventilation with sufficient airflow around the unit, do not mount on soft surfaces, for example, carpets or soft fabrics. connection to mains supply Before performing any connections or disconnections ensure that the power on/off switch (5) of the unit is in "off" position. Always check that the voltage and frequency of the mains supply corresponds to the specifications as labled on the unit!Connect the power cord's IEC type plug into the power inlet connector (6) of the Obelisk. Connect the power cord's mains plug to your power outlet. input connections The Obelisk has 5 pairs of high quality RCA (cinch) input connections. Number 1 input (22, 23) is a line level connection in a standard configuration. This input, however, can be optionally equipped with the Heed Audio vinyl-1 MM phono module for connecting a turntable, or with the Heed Audio dactyl-1 D-to-A converter module for connecting a CD-transport (or a CD-Player via its digital output respectively), computer music server, or any other source with a digital co-axial output. Number 2 to 5 inputs (14-21) are standard line level inputs. See specifications section for sensitivity data of the inputs. loudspeaker connections The Obelisk is equipped with high quality loudspeaker connectors suitable for 4mm banana plugs, max. When connecting the loudspeaker cables ensure that the speakers are phased correctly i. e. "+" (red) to "+" and "-" (black) to "-". pre-out connection (pre-amplifier output) Your Obelisk Si has a pre-out (RCA) connection (12, 13). Here you can connect an additional Heed Audio Obelisk PAS stereo power amplifier for bi-amplification, or, alternately, make use of this facility to connect your Obelisk Si to an analog recording device (tape or CD recorder), or headphone amplifier, ideally our Heed Audio CanAmp. If you want to use your amplifier this way, you need to change the position of the jumper on the PCB behind the connection. Remove the housing cover of the Obelisk Si. Change the positions of the jumper >>> to . . . . . Connect your recorder or headphone amplifier (see "installation" section on page 5-6). operation When the above placement and connections are correctly completed, your Obelisk is ready for action!Turn the Volume Knob (1) counter-clockwise to the minimum setting. Switch on your desired source components. Switch on your Obelisk with power on/off switch (5) on the back-plate and allow some time (5-10 minutes minimum) for warming up. If your unit was transported or stored in cold environment allow it to warm up to room temperature before switching on!Select the component that you'd like to listen to with the Input Selector Switch (2). [. . . ] Connect your turntable, CD-Transport, or CDPlayer interconnecting cable to Input 1 (22, 23). OBELISK X-2 power supply The Obelisk X-2 is an optional auxiliary power supply which not only increases the output power of the Obelisk Si integrated amplifier but also dramatically improves its sonic performance. In this enhanced 2-box configuration, the Obelisk X-2 will support the power amplifier stage of your Obelisk Si integrated amplifier while the built-in power supply will continue to support the pre-amplifier stage alone. This means that after connecting the X-2, the power cable of the Obelisk should remain connected as well. connecting the Obelisk X-2 to the Obelisk Si Before performing any connections or disconnections ensure that the power on/off switch (5) of the unit is in "off" position. Connect the supplied special connector of the auxiliary power supply to its socket (7). [. . . ]
