17. DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPASHING
AND ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS
VASES, ARE PLACED ON THE EQUIPMENT. "
18. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN
READILY OPERABLE.!
TO PREVENT ELECTRIC SHOCK DO NOT REMOVE TOP OR BOTTOM
COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL. !
TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE AC
MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE
AC RECEPTACLE. THE MAINS PLUG OF THE POWER SUPPLY CORD
SHALL REMAIN READILY OPERABLE. !
WATCH FOR THESE SYMBOLS:
The lightning bolt triangle is used to alert the user to the risk of electric
shock. !
The exclamation point triangle is used to alert the user to important
operating or maintenance instructions. !
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as pre-
amplifiers directly above or below the unit. Because this amplifier has a
high power density, it has a strong magnetic eld which can induce hum
into unshielded devices that are located nearby. The eld is strongest just
above and below the unit.#

System
Niko1300 is a truly “over-designed” amplifier
performing in any musical and sonic conditions with an
unprecedent dynamic. A unique high-end power
amplifier capable to drive the most demanding and
challenging loudspeakers on the market keeping a
superb sonic performance. !
Power amplifier
Niko1300M is a dual monobloc class A/B power
amplifier with 1300Wrms at 8Ohm and 1950Wrms at
4Ohm. With a 10Hz – 90KHz band-pass @ -3db
across all power levels.!
Power supply
Niko1300M have a dedicated analog power supplies
use two separate custom design 1000VA toroidal
transformers.Two capacitor filtering banks provide a
massive 100.000µF running at 85V with the capability
to store up to 300joule of energy to support even the
most demanding dynamic situation with even the
hardest loudspeakers like a band or orchestra is
performing right in front on you.Even for the power
supplies stage the electrical connections are made by
gold plated 4mm solid copper busbars to insure a
perfect and long-life electrical connections. !
Accordingly Niko1300M can manage an input voltage
between 110-260V with 50-60hz.#

Main Power switch
The circuit bracker [fig 1.1] of the Niko1300M is
located in the power panel section of the rear
panel.This special circuit breaker is a fuse-less bracket
that operate only with the magnetic principle.!
•OFF: the Niko1300M is isolated from that mains
power. Never turn off the circuit breaker before
wait 10 second from the standby

•STANBY (status led blue) : the Niko1300M is not
isolated from that mains power. the amplification
stages is power off. Only in this phase is safe to
operate with the input and output connection.
•ON (status led green) : the Niko1300M now is
completely turned on. the amplification stages are
fully power on. The system check before unmute
the output last 6 second.
Input selector switch
The input selector [fig 1.3] switch is located in the
center of the rear panel. It switch between balance
(XLR) and unbalance (RCA) input. !
Input gain selector
The gain selector [fig 1.4] is located under the input
selector switch. The gain selector is a input attenuator.!
