User manual HARMAN KARDON FS1

[. . . ] The FS1 is alone among audio power amplifiers in being designed to accommodate the long speaker runs required for multiroom applications without sacrificing the ultrawidebandwidth circuitry and high-current capability technologies that are key to Harman Kardon's long-standing tradition of audio amplifier excellence. As an added audiophile touch, five-way speaker terminals ensure a secure connection to large-gauge speaker wire, and individual output level trim controls enable output balance to be set precisely. Along with power and performance, the FS1 provides the flexibility for a variety of applications. Depending on your needs and system requirements: the FS1 may be configured to serve as a two-channel, high-power amplifier for the rear surround channels in the new 6. 1 or 7. 1 digital audio systems; it may be used to power two separate remote zones or four separate remote rooms; or ­ for the ultimate in flexibility ­ it can even provide power to a multiroom zone and rear surround channels at the same time! [. . . ] ---------------------------------- One Input/Four Outputs This is the standard configuration, and it is the way the unit is shipped from the factory. If you wish to have one input feed sent to all four amplifier channel pairs, leave the Amplifier Mode Switches as they are and connect the audio source to the Main Input /. For this configuration, the speakers should be connected as shown in Figure 1, with each channel connected to the appropriate terminals TM/£/¢/. Channel 3 Right Speaker Left Speaker Channel 1 Right Speaker Left Speaker "Bridge 1" should be used, with the connections to the proper "+" and "­" terminals with the two outer-oriented, vertically binding posts on each side of the channel pair, as opposed to the horizontal orientation of normal speaker connections. DO NOT use the standard channel output and polarity markings for the Channel 1 and Channel 2 amplifiers. The remaining two speaker pairs for Channel 3 and Channel 4 are connected as shown in Figure 2, using the standard markings. In addition to the speaker connections, the following steps must be followed for this configuration: · Connect the audio input source to the Main Amp Input Jacks /. · Locate the Bridge 1 Amplifier Mode Switch on the rear panel, and use a #1 Phillips screwdriver to carefully remove the screws on either side of the plastic switch guard that is around the switch. · Remove the plastic guard and set it aside with the screws. · Slide the switch to the left so that it is under the phrase "BRIDGE 1". · Replace the plastic switch guard with the two screws so that the switch is secured in the proper position.

Connect the speakers and audio inputs as follows: · Connect the source that is to be fed to three speakers to the Main Amp Input Jacks /. The speakers that are to receive this signal should be connected to the Channel 1 Speaker Output Terminals ¢, the Channel 2 Speaker Output Terminals and the Channel 4 Speaker Output Terminals £ using the standard speaker wiring markings on the rear panel, as shown in Figure 1. · Connect the source that is to be fed to only one channel to the Channel 3 Input Jack >. · Move the Channel 3 Separate Switch ¤ to the left so that it is under the word "ON". · Connect the speaker pair that will receive the separate input feed to the Channel 3 Speaker Terminals TM using the normal wiring connections and markings as shown in Figure 1. · Make no changes to the Amplifier Mode Switches /°. Leave them in their factory positions with the switch over the word "NORMAL". are to receive this signal to the speaker terminals marked "Bridge 1", as shown in Figure 3. Make certain that the connections for these speakers are made to the proper "+" and "­" terminals with the two vertically oriented binding posts on each side of the channel pair, as opposed to the horizontal orientation of normal speaker connections. DO NOT use the standard channel output and polarity markings for these speaker connections. · Connect the other input source to the Channel 3 Input Jack >. [. . . ] After turn-on the volume may be adjusted to any point in its range. · Consult the instructions packed with the optional keypads for additional information on changing these settings from the remote room. 13 OPERATION Service Information If your installation has followed the procedures in this manual, you should enjoy many years of trouble-free operation and high-quality listening enjoyment.
