CONNECTIONS & CONTROLS
MAKING CONNECTiONS
• Plug connection to INPUT 1 (CH1) – check that
the MIC/LINE switch matches the source (Mic for
microphones and instruments, Line for mixers,
keyboards, or instruments with active pickups).
• Plug connection to INPUT 2 (CH2) – proceed in
the same manner as with INPUT 1.
• Plug connection to INPUT 3 (CH3) – STEREO
jack is well suited to use with mobile phone, mo-
bile audio device, or computer.
• 10dB LINE jacks is well suited for use with key-
board, drum machine, or other line level devices.
See Bluetooth® Controls section to use a wire-
less device as the source for INPUT 3.
POWERING UP
• Turn on the power to any devices plugged into
Input 1 (CH1) , Input 2 (CH2), or Aux Input (CH3)
and ensure their output volumes are turned up.
(Generally, the best sound can be achieved by
turning output device volume to maximum, then
making any volume adjustment via the input gain
controls of the AS8 AC/DC).
• Power ON the AS8 AC/DC.
• Slowly turn INPUT 1 (CH1) GAIN, INPUT 2 (CH2)
GAIN, and INPUT 3 (CH3) GAIN to the desired
levels.
POWER/CLIP LED AND PROPER LEVELS
• This LED on the AS8 AC/DC should normally be
green when its AC power cord is connected to an
electrical outlet, and the Power Switch is turned
on.
• If this LED is constantly turning red, it means that
one of the input signals is too high.
• Turn down each input gain volume knob in turn to
nd which is distorting, and set that knob to clip-
ping.
FLOOR MONITOR APPLICATIONS
• Turn the LOW Equalizer knob down slightly to re-
duce unwanted rumble and low-frequency build-
up. This will reduce feedback and make vocals
clearer.
• Power ON the AS8 AC/DC. Slowly turn INPUT 1
GAIN, INPUT 2 GAIN, and INPUT 3 GAIN to the
desired levels.
LINKING MULTIPLE SPEAKERS
• If linking multiple speakers, connect all input
sources to the rst AS8 AC/DC to the LINE IN
connection of the next AS8 AC/DC, and continue
the daisy chain to the last AS8 AC/DC. (This is
common where multiple monitor mixers share the
same feed from the mixing board.)
• To avoid “pops” when turning power on/off, the
last AS8 AC/DC should be powered on last, and
powered off rst.

SETUP
BLUETOOTH CONNECTION: To use a Bluetooth-enabled device like your phone or computer as the
source for Input 3, you must rst “pair” it with your AS8 AC/DC.
1. Power on your AS8 AC/DC and enable Bluetooth on your source device (phone, computer, or
other mobile device).
2. From your source device, display its list of discovered Bluetooth devices and look for “AVANTE
AS8 AC/DC” there. If your device is unable to nd the speaker, try scrolling down the list to make
sure it’s not hidden off-screen. If it’s not listed, push and release the PAIR/play/pause button on
your AS8 AC/DC.
3. Once “AVANTE AS8 AC/DC” appears on the list, select it. Your source device and your AS8 AC/
DC will pair, and the AS8 AC/DC will chime and illuminate the Bluetooth LED to indicate that the
connection was successful.
4. Play audio from your Bluetooth source device, and it will now play via INPUT 3 of your AS8 AC/DC
as the Bluetooth LED slowly ashes.
5. Pressing the PAIR/play/pause button will now remotely control the play/pause action of your de-
vice, with the Bluetooth LED ashing during play, and solid while paused.
6. To “disconnect” your Bluetooth device from Input 3, press and hold the PAIR/play/pause button.
The LED will turn off and you will hear a chime.
7. When you power on your AS8 AC/DC, it will look for any previously paired device, and pair with it
automatically if available.
TWS INSTRUCTIONS:
1. Power on speakers, and press the PAIR button to pair each speaker. The speakers do NOT have
to be paired in any particular order, and both should be available for pairing.
2. Use the TWS button on each speaker to determine which speaker is the primary (left channel) and
which is the secondary speaker (right channel). The speaker whose TWS button is pressed rst
will be set as primary speaker. When TWS lights of the two speakers ash, the TWS features of
these two speakers will be connected, and the PAIR light of the secondary speaker will automati-
cally turn off. The secondary speaker will not be available for pairing.
3. Enable Bluetooth on your mobile phone, search for the primary speaker and connect with it.
Notes:
• Press the PAIR button to turn on Bluetooth. If the PAIR indicator blinks, the speaker is now in pair-
ing mode. If the speaker is not connected to any devices (including the TWS connection) within 5
minutes, the PAIR indicator switch off and the speaker will automatically exit pairing mode. When
you use speaker in single mode, if its TWS button is pressed, the TWS light will blink for 2 min-
utes then will automatically switch off, which will not affect the speaker’s ability to operate in single
mode.
• In single speaker mode, the outputs of the L+R channels will be mixed. When you connect two
speakers with TWS, the primary speaker is the left channel and the secondary speaker is the right
channel.
• To exit TWS mode, press the TWS button on either speaker. The secondary speaker will be re-
leased and enter pairing mode.
• If the TWS connection is not disconnected by pressing the TWS button, the two speakers’ TWS
will be automatically connected after pressing the PAIR button when speaker power on.
• If two speakers are connected with TWS, you can press the PAIR button on either speaker to turn
off their Bluetooth at the same time.

HANDLING PRECAUTIONS
Do not short circuit the battery. Avoid subjecting the battery to a short circuit, as doing so gener-
ates a very high current, resulting in overheating, electrolyte gel leakage, harmful fumes, explosion
risk, or other damage to the battery.
Mechanical shock. Dropping, impacting, striking, or bending the unit, or subjecting the unit to any
other types of mechanical shock may cause failure or shortend life of the battery.
Do not disassemble the batteries. Never disassemble the batteries, as doing so may result in an
internal short circuit in the battery, leading to fire, explosion, release of harmful fumes, or other haz-
ards. Electrolyte gel is harmful, and contact should be avoided whenever possible. Should the elec-
trolyte gel come into contact with the skin or eyes, flush the area of contact immediately with fresh
water and seek medical attention immediately.
Do not expose battery to heat or fire. Never incinerate or dispose of the batteries in fire, as this
could result in an explosion.
Do not exposre the battery to water or liquids. Never expose or immerse the batteries in liquids of
any type, including water, seawater, soft drinks, juices, coffee, or other beverages.
Battery Replacement. For battery replacement please contact customer support.
Never use a damaged battery. Shipping carries a risk of damage to the battery. Should damage
be observed, including damage to the plastic casing of the battery, deformation of the battery pack-
age, chemical or electrolyte odor, or leakage of the electrolyte gel, or any other miscellaneous dam-
age, DO NOT use the battery. A battery with a odor of electrolyte or a gel leakage should be placed
away from fire to avoid risk of fire or explosion.
Battery Storage. The battery should be stored at room temperature, with a charge of at least 50%.
During long periods of storage, it is recommended that the battery be charged every 6 months.
Doing so will prolong the life of the battery and will also make sure that the battery charge does not
fall below the 30% mark.
Other Chemical Reactions. Because batteries rely on a chemical reaction to work, battery perfor-
mance will deteriorate over time, even if stored for a long period of time without being used. In addi-
tion, if various usage conditions (such as charge, discharge, ambient temperature, etc.) are not main-
tained within the specified ranges, the life expectancy of the battery maybe shortened or the device
in which the battery is used may be damaged by electrolyte gel leakage. If the batteries cannot
maintain a charge for long periods of time, even when they are charged correctly, this may indicate
the need to replace the battery.
Battery Disposal. Please dispose of battery according to local regulations.

BATTERY RECHARGING:
To recharge the battery, plug one end of the supplied AC cord into the AC input on the side of the
unit, and the other end into a matching power supply. It is recommended to disconnect the unit
from the charger once the battery has reached full charge. Doing so reduces the risk of over-
charging the battery, which can shorten the service life of the battery.
NOTE: When unplugging the unit from charging and then applying power via battery, there will be a
small charge drop.

TROUBLE SHOOTING
Mixer and amplier will not turn on.
Check whether the included power cord is securely plugged in to a working power outlet.
Amplier turns off suddenly.
Check whether any of the device’s vents are blocked. Since inadequate ventilation will cause the de-
vice to overheat, turn off the mixer and uncover the vents to allow the product and its internal ampli-
er to cool. After a few minutes, the product should reset itself and can return to normal playback.
The POWER/CLIP LED is ashing continuously.
If the POWER/CLIP LED is ashing, the amplier is being used beyond its design capabilities. Turn
off and on and resume playback.
No sound from the speaker(s).
Check that the external instruments and/or microphones are connected correctly to inputs, that those
sources are powered on, and that all cabling is functional. Check that the input gain controls of all ac-
tive inputs are set appropriately. If using Bluetooth®, ensure that the AUX/BLUETOOTH switch set is
to Bluetooth, that your source device and AS8 AC/DC have successfully paired, and that your source
device is still active (not asleep or out of battery power) and audio with its output level control is set to
an audible level.
Distortion/noise in the audio signal, or low output level.
You will generally get the lowest noise (hiss) by setting source device output to max, and then making
any reductions of the volume via the AS8 AC/DC input gain knobs. Check that the output levels of any
source devices are set appropriately, and that the INPUT GAIN controls for all inputs are set to ap-
propriate levels. Check that the MIC/LINE switches of each input are set appropriately, as well. Check
whether both the STEREO jack and the -10dB LINE IN jacks on INPUT 3 are being used (connected)
at the same time. If the POWER/CLIP LED is lighting, try adjusting each INPUT GAIN knob in turn to
nd which is the source of clipping.
Sound level is too loud during voice announcements.
Check whether the INPUT GAIN level for the mic input is set too high, or whether the levels for your
other inputs are set too low, either on the source device(s), or at their INPUT GAIN controls.
Out of the effective Bluetooth® audio range of the device.
Effective line-of-sight range is up to 50 feet. The wireless performance of the device is signicantly
affected by walls or metal, interference by WiFi, or other wireless devices.
