Features：
Toroidal transformer, 12 8200u high resistance capacitors,
broader frequency range,less distor tion, more attractive tonal
effects
15 pairs of Motorola high wattage transistors, powerful output,
accurate reversion. heat tunnel structure, effective heatsink
One-body steel enclosure design. The transformer is secured from
above and below,
viberation proof, can resist pressure better.
Soft start at startup, transient proof design,better protecting
any connected equipments.
Efficient fan cooling system:the fan will word under low speed when
the heatsink’s
temperature is below 60 degree Celisius; it wil automatically adjust
the speed accordingly
when the temperature is between 60 to 80 degree Celisius.This keeps
the noise as low as possible.
Automatic limiter:by detecting the output signal.when the system
is overloaded,
autiomatically start signal amplitude limitation, to ensure the
speakers are not damaged.
other protections:overload,thermal, short circuit protection.
Utilizing international standard parts in circuit desigh, offering
higher stablility.
Suitable for gymnasium. large show ,disco, pub etc.

Features：
N series public broadcasting power amplifier with preamplifier
have four varieties, there are N100A, N150A, N250A, N350A, N450A,
N550A,these products can provide the output power separately 100W,150W,250W,
350W, 450W, 550W,they can be applied to the public broadcasting
invarious fields and the amplification of background music.
All of this series have a preamplifier. The unit has three microphone
inputs, and one is first with mute function; it has two line inputs,
they can be linked to all kinds of sources as CD, radio and recorder
etc. The level of microphones or lines can be adjusted separately.
The unit provides one line output, it can be used for recording
or linking to other amplifier. All these products are equipped
with reliable shortcut and overload protection.
The output methods of this series are 4-16ohm,70V and 100V(120V)
Mic input:600ohm-60dB.
