INTRODUCTION
Thank you for purchasing the AR2300.
AR2300 is a high-end black-box type receiver ith ide band coverage bet een 40kHz and 3.15GHz. Some of its
outstanding features are:
1) Digital signal processing:
Input signals after the 45.05MHz IF are converted from analog to digital by a DSP processor. There is no AGC in
the analog processing unit, as all processing, including AGC, is done by DSP.
2) High-performance analog front-end:
Analog signal processing is performed by a computer simulated, high-performance distribution constant filter.
3) DDS local oscillator:
Instead of the conventional PLL method, the first local frequency is produced by direct digital synthesis. That
method allo s frequency s itching at high speed.
4) IF output:
An analog IF of 15MHz (+/-7.5MHz) band idth is output.
5) Digital I Q output:
A digital I/Q signal of 0.9MHz is output via a USB 2.0 interface.
6) High precision frequency reference:
0.01ppm frequency stability of the 10MHz internal master oscillator is achieved hen using the optional GPS
receiver unit.
7) FFT analyzer:
Thanks to the onboard FFT processor, 10MHz ide spectrum data can be output at high speed via serial.
8) Optional APCO25 Phase 1 digital voice demodulation
9) Video demodulation
By connecting and external TV monitor, it is possible to demodulate the signal of FM modulation security
cameras and analog TV broadcasts. When you connect the TV monitor, you can check the demodulated video.
Not compatible ith digital terrestrial television.
10) Simultaneous monitoring
2 band reception, offset reception, triple reception (restrictions apply).
11) SD card slot
You can record the received audio on SD, as ell as backing up receiver settings and memory data.
12) 12kHz analog I Q output
Allo s DRM broadcasts decoding via a PC and dedicated 3rd party soft are.
13) HF direct sampling
When receiving HF signals, the signals are converted directly to digital ithout entering the mixer. This allo s
very good linearity characteristics.
14) Control via LAN Internet with optional ARL2300 Ethernet Controller
Please read this operating manual carefully. This information ill allo you to enjoy maximum performance from
your receiver. Due to continuous developments of the receiver, firm are and soft are, e ackno ledge that there
might be some changes, errors or omissions.
We sincerely hope that the AR2300 ill be your monitoring companion for many years to come.

SAFETY PRECAUTIONS
DO NOT operate the receiver near unshielded electrical blasting caps or in an explosive atmosphere. This could cause
an explosion and death.
DO NOT operate the receiver ith a headset or other audio accessories at high volume levels. If you experience a
ringing in your ears, reduce the volume or discontinue use.
DO NOT directly apply AC po er to the DC socket on the receiver rear panel. This could cause a fire or damage the
receiver.
DO NOT apply more than 16 V to the DC socket on the receiver rear panel. This could cause a fire or damage the
receiver.
DO NOT reverse the DC po er cable polarity. This could cause a fire or damage the receiver.
DO NOT let metal, ire or other objects contact the inside of the receiver, or make incorrect contact ith connectors
on the rear panel. This could cause an electric shock or damage the receiver.
DO NOT operate or touch the receiver ith et hands. This could cause an electric shock or damage to the receiver.
Immediately turn OFF the receiver po er and remove the po er cable from the receiver if it emits an abnormal odor,
sound or smoke. Contact your AOR dealer or distributor for advice.
DO NOT put the receiver on an unstable place here the receiver may suddenly move or fall. This could cause an injury
or damage the receiver.
DO NOT operate the receiver during a lightning storm. It may result in an electric shock, cause a fire or damage the
receiver. Al ays disconnect the po er source and antenna before a storm.
DO NOT expose the receiver to rain, sno or any liquids.
DO NOT change the internal settings of the receiver. This could reduce receiver performance and / or damage the
receiver. The receiver arranty does not cover any problems caused by unauthorized internal adjustments.
DO NOT install or place the receiver in a place ithout adequate ventilation.
DO NOT use harsh solvents such as Benzine or alcohol hen cleaning, as they ill damage the receiver surfaces.
DO NOT leave the receiver in areas ith temperatures belo 0°C or above +50°C.
DO NOT place the receiver in excessively dusty environments. This could damage the receiver.
DO NOT place the receiver against alls or put anything on top of the receiver. This may overheat the receiver. The
receiver ill become hot hen operating the receiver continuously for long periods of time.
Turn OFF the receiver’s po er and / or disconnect the DC po er cable hen you ill not use the receiver for a long
period of time.
The AR2300 may receive its o n oscillated frequency, resulting in no reception or only noise reception including on the
spectrum displayed by control soft are, on some frequencies.
