the subwoofer. No audio passes down the CAT5 type cable, only control signals. The CAT-5 cable should not be
plugged into an IP or network output socket otherwise damage may occur to the source equipment. Furthermore,
the CAT cable should not carry an IP signal.
Two hardware remote controls (SRC 1 and SRC 2) are available from Klein + Hummel together with various
lengths of high-quality CAT-5 cable with EtherCon connectors (RC nn). The signals on the cable are as follows:
For connection options see Volume Control section. A * * * * indicates RS-232 data connections.
Finally, there is a VOL

Amplifier Module(s)

The O 810 has one amplifier module. The O 870 has two amplifier modules – one for each driver. The amplifier(s)
use D-class technology to minimize heat dissipation and are run in bridged mode to minimize distortion. Even so
some space (5 cm, 2") is required around the electronics panel. In other technical aspects, such as harmonic
distortion, intermodulation distortion, and noise, the performance is as good class AB designs.

Driver(s) and Acoustical Response

Driver(s) and Acoustical Response Driver(s) and Acoustical Response Driver(s) and Acoustical Response
The driver(s) are the best available for their application. Long throw, efficient, low distortion drivers ensure a
clean sound quality even at high replay levels. The driver(s) is/are loaded by the internal volume of the cabinet
and is/are magnetically shielded for use next to CRT screens and magnetic storage media. The system's SPL
output and the cabinet volume can be seen in the Specifications section below.
Klein + Hummel subwoofers are designed to have a flat pass band magnitude response in anechoic conditions
when all the acoustical controls are set to 0 dB. When a subwoofer is installed into a listening environment the
response changes and thus should be corrected back to a flat response. It is therefore expected that the
acoustical controls will need adjustment to improve the in-situ response of the subwoofer. The acoustical
controls' settings depend on the subwoofer's location and will probably be different for the same subwoofer type
installed in different locations in the same room. Moving the cabinet small distances, 50 cm (20"), can
dramatically change the response therefore resulting in different acoustical control settings.
