1. Turn off all powers of devices to be connected.
2. Connect the amp output line to "CH NNEL INPUT" on the rear panel. Caution to polarity (+/-).
3. Connect the speaker line to "CH NNEL OUTPUT" on the rear panel. If connection is completed, then turn
the power of other devices.
4. Connect DC-24V to the DC power input of SC-6224, then push the power switch.
- OPERAtIOnS
1. Impedance setup and save for each channel
1) If "Confirm" button on the front side is pushed, impedances of speakers connected to speaker lines from
channel 1 to 24 will be measured and default value will be saved. Previously measured default value will
be deleted and new measured value will be saved.
2) LED status will be displayed as follows depending on impedance values has been measured.
- Green LED : speaker is connected normally.
- Orange LED : speaker line is SHORT.
- LED Off : speaker is not connected.
2. Manual Speaker Test
1) If "TEST/ST RT" on the front panel is pushed, impedance of speaker can be tested manually. This
function performs the test about the channel which speaker is connected, compares with saved
impedance, and display the result on the front LED.
- Green LED – speaker impedance in normal range
- Red LED – speaker impedance out of normal range
- Orange LED – speaker line is Short
- Red LED flickering – speaker line is Open
3. uto Test Mode
1) It is automatic test ON/OFF button of speaker line. If button is on, it checks out the speaker line
automatically for certain time setting and displays the result on each channel's LED. Setup the automatic
test mode by pushing " UTO CHECKER" button on front panel.
2) If LED is on, it means the automatic mode is set, and check time for automatic mode can be set from 5 to
200 minutes by turning the time adjustment volume on the front panel.
- Green LED – speaker impedance in normal range
- Red LED – speaker impedance out of normal range
- Orange LED – speaker line is Short
- Red LED flickering – speaker line is Open
