AMPLIFIER OPERATION GUIDANCE
100V Line System
For 100V line systems, connect the amplier to the rst speaker in the system using double-insulated speaker wire which has
adequate current rating to handle the total output of the amplier.
Connectthe“100V”outputterminaltothepositive(+)connectionofthespeakerand“COM”outputtothenegative(-)connectionof
the speaker. Connect further speakers in parallel to the rst speaker with all positive terminals and connected together and all
negative terminals connected together as shown below.
Speaker Terminals
These terminals are oering 3 low voltage outputs 4Ω, 8Ω, 16Ω depending on your speaker combination. A 70V/100V commercial
output is also available. Please note that one wire only should be connected to COM screw and one wire to the selected impedance
or voltage. Multiple combinations cannot be done at the output level. Four dierent types of connections are provided.The
low impedance section: 4Ω, 8Ω, 16Ω is designed for a small amount of speakers to be connected to your amplier. The 70V/100V
section is especially designed for a multiple speaker distribution.When using the 70V/100V output, speakers have to be equipped
with 70V/100V transformer. The maximum amount of speakers to be placed on your distribution line is in relation to the power
allocated to each speaker. The total wattage set on the secondary side of the transformers on your speaker line must not exceed the
maximum RMS output power: 120W to 240W. Failure to respect this may cause permanent damage to the amplier.
A 100V line speaker system can comprise of many speakers connected together.The determining factor for how many speakers can
be used on a single amplier is the power rating. For most purposes, it is advised to connect as many speakers as needed with a
combined wattage of no more than 90% of the amplier’s output power rating.
Theterminalsofa100Vspeakerareconnectedtoatransformerandinsomecases,thistransformermaybe“tapped”fordierent
power ratings.These tappings can be used to adjust the wattage (and output volume) of each speaker in the system to help achieve
the ideal total power of the system for the amplier.
The mixer amplier is featured of 6 speaker zone outputs, either one of six zone or total six zone power loading shall be equivalent or
no higher than the rated power of the amplier.
