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. [. . . ] Line level input left channel installation We believe that a Heed Audio component should be, optimally, installed by an approved Heed dealer. Nevertheless, the procedure is straight-forward enough that you may install your new Obelisk Si yourself by following the instructions contained herein. 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. 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. 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!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! [. . . ] Connect the module to the main PCB of the amplifier by sliding it on the pin connectors (24, 25). Change the positions of the jumpers (26, 27) >>> to "phono". Re-connect all cables (see "installation" section on page 5-6). [. . . ]
