This supplied with the IC U4, the tone control at Source Direct OFF position.

The IC U3 and U4 are buffered by an "AD712" reference. U11 (German V.) and transmits the signal as a preamplifier to the IC U5 JRC4556 headphone amplifier and to the power amplifier when the tone control is on OFF.

After switching the Source-Direct switch on (On), the U3 alone, as a preamplifier, directly supplies the power amplifier.

Thus, this Harman HK690 is not completely discreet, like the older integrated amplifiers from Harman / Kardon.

The HK690 is mostly identical to the HK650 (built in 1999) and the HK690 is a successor of the HK680.

note the EU vs. international Version:
- The German or European Version of the HK 690 is constructed according to the Service Manual different from the International Version. The difference is that a J-FET IC AD746 (U3) is installed in the international version and a NE5532 is installed as an IC (U3) for the German market.

According to the Service Manual, the German or European version of the HK 690 has a different structure than the International version. The difference is that a J-FET IC AD746 (U3) is installed in the international version and a NE5532 is installed as an IC (U3) for the German market.
