User manual HARMAN KARDON HK 675

[. . . ] Connecting the unit to an outlet supplying a higher voltage may create a fire hazard. Handle the Power Cord Gently Do not disconnect the plug from the AC outlet by pulling the cord; always pull the plug itself. If you do not intend to use your unit for any considerable length of time, turn the unit off completely by pressing the round Power button above "Power" (see page 5). Do not place furniture or other heavy objects on the cord, and try to avoid dropping heavy objects on it. [. . . ] Other manufacturers' remote sensors and components may not be compatible, but it will not hurt to experiment. A second wire may be used to connect your amplifier's REMOTE OUT jack to the Remote Input of another stereo component. Continue this process to include additional components (if compatible). For best performance, use high quality speaker cables. However, ordinary copper wire can be used if the gauge meets the following requirements: Wire Length Up to 2. 5 meter Up to 4 meter Up to 6 meter Above 6 meter Min. Diameter 1 mm 1. 25 mm 1. 6 mm 2-2. 5 mm IMPORTANT: When connecting two pairs of speakers, determine the impedance of each pair by looking on the back of the speakers, in your owner's manual, or by contacting your dealer or manufacturer. You can listen to two pairs of speakers at the same time ONLY if the impedance of EACH speaker is NOT LESS THAN 8 Ohms. WARNING: Do not play sets of speakers simultaneously except as recommended above. Digital Loop-Through Digital inputs and outputs are provided only as a convenience for connecting various digital components to the "CD", "CDR" and "AUX" digital inputs. The corresponding digital input signal is fed to the "DIGITAL OUT" connector when "CD", "CDR" or "AUX" is selected as input source, to provide a digital signal for CD or MD Recorders. The HK 675 cannot process, decode or convert any digital signal. AC Power Plug the cord into a 230 VAC wall socket. 2. Avoid rolling excess wire with or near signal interconnects. 4 CONNECTIONS Controls and Functions HK 675 Power switches Press the round Power button (above "Power") to turn the amplifier on for the first time.
