Feedback Eliminator - AM-898's real-time feedback eliminator
processor was designed to provide state-of-the-art feedback elimination
processing, while maintaining a simple control interface. You just select
one of the 3 room sizes and it will automatically filter out howling
feedback noise from the speakers. This is a necessary function for any venue
that is looking for a professional sound environment or any KJ who are
looking to prolong your speakers' life.
Vocal Eliminator - AM-898 has a powerful vocal eliminator
processor that can take out up to 90% of vocals from any regular audio CD.
The AM-898's DSP utilizes one of the most powerful vocal elimination
algorithm which removes more vocal with less impact on the background
instruments. You can easily turn any regular CD into a karaoke track and
begin your karaoke performance.
Music Volume Auto Leveling - When you play audio tracks, some
songs are louder than others even though the volume of your system remains
the same. When you turn on the "Music Volume Auto Leveling" function, the
AM-898 Amplifier will automatically adjust your music to one of the six
preset volume level. If your music level is too low, the AM-898 will boost
the audio signal, and if the music is too loud, it will decrease the music
volume back to your pre-set volume level. This function will eliminate lots
unnecessary adjustment for KJs.
Digital Effect Processor - The AM-898 has a powerful built-in
Reverb and Echo Effects that can dramatically increase the quality of your
performance. A "reverb" is created when a sound is produced in an enclosed
space causing a large number of echoes to build up and then slowly decay.
Reverb is most noticeable when the sound source stops but the reflections
continue, decreasing in amplitude, until they can no longer be heard. The
AM-898 enables you to adjust the reverb time, reverb level, echo repeat and
echo delay to optimize your sound effects.
3-Band Music and 5-Band Microphone Equalizer (EQ) - The AM-898
has two independent band equalizers for music and microphone volume. Using a
powerful EQ, it can compensate for your music or singer's shortcomings or
when you would like to add more treble or bass to your performance. For
music, the 3 band frequencies are available. For the microphone, 5 frequency
bands are available. You can fine tune each frequency to your desired level.
Microphone Noise Gate - This powerful auto-mute function enables
your mixer to automatically turn off the microphone when it is not in-use.
The powerful noise gate function allows a microphone signal to pass through
only when it is above the preset threshold value from 1 to 40. The mixer
utilizes an advanced fading technique to cut in and out of sound so you will
not hear your microphone abruptly cut off once it has fallen below the
threshold or hear a loud click when the noise gate re-opens from mute.
5 Microphone Inputs - The am-898 includes 3 microphone inputs in
the front and 2 inputs from the rear. The rear inputs also enable you to
connect to most wireless microphone units while reducing the messy cables
going from the front.
S/PDIF Digital Input - AM-898 has a coaxial input to carry
digital audio signals from your player to the mixer. Using the S/PDIF
connector, you can send the purest audio signal to the mixer without any RF
Auto-Source Detection - The AM-898 has a built-in auto-source
selection function that enables the mixer to automatically play music and
video from one of the 3 available inputs. When the music stops, it will
automatically switch to the background A/V source (BGM) if audio signals are
detected in the BGM input. The AM-898 will switch to another source input if
audio signals are detected and you stop the BGM. This useful function will
keep your entertainment alive even when the performance ends and the DJ is
changing the disc for the next singer.
RS-232 Serial Port PC Interface
(Download Software Here)- AM-898 has a serial port for PC
connections. You can control all functions of the AM-898 Mixing Amplifier
using either 1) pre-bundled Windows™ software or 2) serial commands. This
powerful feature makes the AM-898 a perfect PC karaoke companion.
User Lock-Down Mode - The mixer has built-in 'user lock' feature
that can prevent most users from changing any AM-898s setting. You can also
define the maximum allowed volume for the music or microphone to prevent
users from blowing out speakers. The AM-898 is designed to be used in public
places including bars or karaoke rooms. This useful function will help you
preserve the best sound quality in all occasions.
Subwoofer Signal Control - The AM-898 has 3 powerful subwoofer
settings to fine tune your subwoofer in a 2-way or 3-way speaker. You can adjust 1)
Subwoofer Volume 2) Subwoofer LPF: the Low-Pass-Filter range from 40 to
150Hz enables you to decide how much of the low frequency signal should be
coming from the subwoofer 3) Subwoofer Volume Reducer: this function helps
you reduce subwoofer volume when you are singing. This low frequency
handy when a singer has low vocal range. The AM-898 will automatically
reduce the subwoofer volume to let the singer's voice comes out loud enough
to be heard.
Music and Microphone Balance - this powerful feature is designed
for you to compensate for your irregular room configuration or when your
speakers are not placed symmetrically from the audiences. Using this
function, you can easily adjust both the music level and echo delay for each
speaker to compensate for speakers that are further away from audiences.
5 Preset Memory Recall Buttons - You can save all of your optimal
setting to one of the 5 preset memory buttons. Audio effects such as echo,
reverb, music volume, and microphone volume can be recalled by either
pressing the button on the remote control or on the front panel. Once you
have tuned and saved the your favorite settings, you will never need to
adjust the mixer again.
