7 10. Power cord Connect this cord to an AC outlet of 120 V AC. 11. Ground terminal A functional ground terminal. 12. AC outlet [UNSWITCHED] Continuously supplies up to 500 W of AC power to connected external equipment. 13. Breaker [UNIT] Cuts off the AC power to the unit when its input current exceeds the allowable value.
8 20. 1 W output volume control Adjusts the 1 W OUTPUT level. Rotate clockwise to increase and counterclockwise to decrease. 21. MOH output volume control Adjusts the MOH (Music On-Hold) output signal level. Rotate clockwise to increase and counterclockwise to decrease.
9 5. OUTPUT CONNECTIONS [Output terminals] Each amplifier has 3 speaker outputs: 4 Ω , 25 V and 70 V. Use only one of these outputs for connection. Class 2 wiring may be used. Note: The impedance in the figure below represents the total impedance of the speaker system.
10 6.2. Module Selector Switch Settings Set the rear panel-mounted Module Selector Switch to either the PAGE or BGM position, depending on the output terminal to which the module signal is to be sent. PAGE: Signals from the installed module are only sent to the speaker outputs.
11 [Muted signal settings] Use the unit's internal jumper switch JP301 to select the signal to be muted. Select either the input signal from the TEL, MIC, and MODULE (PAGE) terminals or from the AUX, PROGRAM, and MODULE (BGM) terminals as the signal to be muted.
12 7.5. Changing MIC and PR OGRAM Input T ypes Both MIC and PROGRAM inputs can be changed from electronically-balanced to transformer-balanced types in the procedures as follows. 7.5.1. MIC input • Install an optional IT-450 Line Transformer in the specified location on the printed circuit board.
13 7.5.2. Program input • Install an optional IT-453A Line Transformer in the specified location on the printed circuit board. • Cut off the JP205 and JP206 jumper wires.
14 10. CONTR OL SETTINGS Output levels are adjustable with individual volume controls. For music play or announcement, adjust the corresponding volume control so that the signal indicator lights intermittently. Note that the sound quality is downgraded when the peak indicator remains lit.
