6 zones amplifier
1. FEATURES • • • • • • • • •
3 Mic inputs, 2 Aux inputs and 1 Aux output for link. Speaker general outputs with line transformer 100V, 70V, & 4-16 Ω. Zones outputs with line transformer 100V. Muting function. MIC1 overrides the other audio inputs. Individual Volume control. Low and High Tone control. Vu-meter provided for a quick and easy monitoring of the sound level. Short-circuit protection and alarm. Individual distributor for 6 channels.
2. PRECAUTIONS • •

Do not block ventilation holes. The amplifier should not be placed in areas: - with poor ventilation. - exposed to direct sunlight. - with high ambient temperatures. - adjacent to heat/generating equipments. - with high humidity or dust levels. - susceptible to vibrations. Make sure the power outlet conforms to the plug of the unit. Do not use this unit if the electrical power cord is frayed or broken. Always operate the unit with AC ground wire connected to the electrical system ground. If an alarm rings while power has been turned of and signal has been feed, there must be a trouble of output shorted. Please turn off the amplifier and correct the trouble, then turn it on again.
3. MUTE FUNCTION This amplifier provides Muting function. MIC2, MIC3, AUX1 and AUX2 are automatically muted by MIC1 input (signal from MIC1 overrides the other input signals). The attenuation level can be adjusted from 0 to -30 dB by adjusting MUTE control (10) placed on the rear panel. The factory setting is -30 dB.

6. CONNECTIONS
1. 2. 3. 4.
Mic input connections are made via 1/4” jack on the rear side of the amplifier. Aux input and output connections are made via RCA connectors. Speakers can be connected using spade plugs. This unit can drive Loudspeakers transformer with 70V or 100V line input. Ensure that total power handing capacity of the loudspeakers is not greater than amplifier’s output power. 5. Low impedance Loudspeakers must be connected across the COM and 4 Ω terminals in serial or parallel so that the total impedance is equal or greater than 4 Ω.
