Step 2
Connecting the loudspeakers
Before any connections are made, please ensure that all equipment in the system is turned off.
Loudspeaker wire throughout the system should be good quality, loudspeaker grade audio cable with polarity coding. For loudspeaker wire that runs less than 25 feet, the
cable should be a minimum of 18 AWG, for loudspeaker wire that runs up to 50 feet, the cable should be 16 AWG and for loudspeaker wire that runs longer than 50 feet,
the cable should be at least 14 AWG.
Installation:
Remove 3/8" of insulation from the end of the loudspeaker wires to be connected. Connect the positive lead of the loudspeaker wire (indicated with a "+" or other mark-
ing) to the Red (or positive) loudspeaker terminal. Connect the other loudspeaker wire lead to the Black (or negative) loudspeaker terminal. Connect the opposite end of
the loudspeaker wire to your amplifier making sure that the polarity is preserved ("+" to "+" or Red to Red, and "-" to "-" or Black to Black – see diagram).
Step 3
Listening Test
To ensure that all connections have been made correctly, turn on your system and begin playback of material you are familiar with. Start off by listening at a low volume,
then slowly raise the volume to a comfortable listening level. A proper stereo image should be present. If the loudspeakers do not produce a solid stereo image, please
verify the wiring to ensure that the polarity of the connection is not reversed.
The KORUS K80 MK2 is equipped with powered subwoofers that provide tremendous bass performance. Once the speaker is connected and turned on, a red LED (Light
Emitting Diode) will illuminate to indicate the speaker is in a standby mode. This LED will turn green during play. These speakers are also equipped with the following
features to help adjust the bass of the speaker to your room and taste.
On/Auto/Off
Once connected to your receiver and plugged into the wall outlet, the speaker will need to be turned on and can be left in the “auto” position so it will sense a signal
from your receiver and automatically turn on. The speaker will automatically switch into Standby mode once it does not sense a signal for approximately 10 minutes.
Gain
You can add or subtract bass to suit your taste by adjusting the gain control. Rotate the knob towards 0dB to remove bass or t6dB to add bass.
Input Toggle
Select “Hi Level Input” to draw bass signal from the speaker wire or select “LFE” (Low Frequency Extension) when connected via the receivers Subwoofer output.
Maintenance
Ultimate loudspeakers are finished in a high gloss lacquer and black wood grain vinyl. Cleaning the loudspeakers should be done with a damp cloth. Chemical cleaners
should be avoided, as they may damage the finish.
