Introduction
Congratulations for choosing an IMPACT AG series amplifier for acoustic guitars.
This series is featured by a great flexibility of use and by a particularly detailed and
precise sound.
The highlight of our products is given by the wide range of frequencies reproduced
by the woofer that allows tweeter to operate only in very high frequencies. The result
is a detailed and precise sound but never harsh and sharp.
With this product you will have the chance to make exactly the sound you would like
your audience to hear.

Impact AG 8:
Acoustic guitar amplifier
Frequency response: 40 - 20.000 Hz
Max Power: 400 W
RMS Power: 200 W
Woofer: 8" - 200 mm
Tweeter: 25 mm silk dome
Weight: 11,3 Kg (protection bag included)
Sizes: 350x330x375 mm (LxPxH)
The versatility of this product allows you to use it both for practice or live
performances, both as a monitor and speaker of live performances.
Main Features:
4 input channels:
1) LINE IN 1: balanced or unbalanced input to which you can connect a guitar for
example.
2) LINE IN 2 - 3 : balanced or unbalanced input to which you can connect another
instrument. MIC IN : balanced input to which you can connect a dynamic microphone or
a condenser microphone. There is a "low cut" filter to tone down low frequencies to 120
Hz.
WARNING: NEVER CONNECT AN INSTRUMENT AND A MICROPHONE AT THE
SAME TIME ON THE SAME CHANNEL 2 OR 3. YOU MAY CAUSE DAMAGES ON
THE PRODUCT.
If you are using a condenser microphone that requires +48 V PHANTOM power,
SWITCH OFF the product, connect the microphone, press PHANTOM +48V button
and ONLY AFTER switch on the amplifier.
WARNING: If you don't follow the procedure in this sequence, you may cause
damages both to the microphone and to the product as well!!!
3) STEREO IN 4: this input consists of 2 RCA plugs: Left and Right , to which you
can connect an external source such as CD or DVD
MP3 IN: this input consists of a 3.5 mm STEREO mini-jack to which you can connect
an external source such as an iPod, an MP3 player, a Smartphone, a Tablet, a pc or
a laptop.
From these inputs you may listen to a song or background music.
SETTINGS:
All input channels have the possibility to:
* Adjust the input GAIN ( there is a red LED indicating "clipping" to avoid
saturation of pre-amp. Avoid this LED to light up and in case it lights up you have to
reduce the level).
* Adjust tones +/- 15 db (high shelve 10 KHz) (mid 3 KHz) (low shelve 100 Hz)
* Adjust signal level to effects (N.B.: fi nal result of effects is given by the
interaction of the effects on the channel and sum of total effects.
STEREO CHANNEL IN 3 has the possibility to adjust the GAIN
Further settings are possible on the mixed signal:
* Choose effect to use (all inputs) (**)
* Adjust general level of effects (N.B.: fi nal result of effects is given by the
interaction of the effects on the channel and the sum of total effects).
* Adjust signal amplification
(**) Available Effects:
1. Reverb Hall 1 2. Reverb Hall 2
3. Reverb Room 1 4. Reverb Room 2
5. Reverb Plate 1 6. Reverb Plate 2
7. Echo & FB 1 8. Echo & FB 2
9. Echo & FB 3 10. Echo & FB 4
11. Echo & FB 5 12. Echo & FB 6
13. Chorus & Rev 14. Flanger & Rev
15. Chorus 16. Flanger
4 outputs:
1) STEREO OUT: stereo output (full range) to which you can connect an external
recorder. Its level is set only by the rotary STEREO OUT control.
2) LINE OUT / DI OUT BALANCED are MONO BALANCED outputs (full range) to
which you can connect a mixer , an active speaker or an amplifier; level is adjusted
only by the rotary control LINE OUT.
This output is MONO so, signal from stereo inputs are mixed together .
3) PHONES: STEREO outlet (full range) for headphones: level is adjusted both
by rotary STEREO OUT control and PHONES LEVELS control. The channel is post
fader and consequently all settings made on each channel and generally on all
effects are present . These independent outputs can assure a great versatility of
use.
For example, you can keep IMPACT AG 6 volume to zero and listen with the
headphones all that has been connected to it. You have the possibility to record
what you are playing, adjusting independently recording volume from headset
volume or even use the IMPACT AG 6 as a monitor and connect it to a bigger system
(such as on stage installations) by adjusting the signal through the rotary LINE OUT
control.

* Adjust signal level to amplifier
Further settings are possible on the mixed signal:
* Choose effect to use (all inputs) (**)
* Adjust general level of effects (N.B.: fi nal result of effects is given by the
interaction of the effects on the channel and sum of total effects).
* Apply and adjust Notch Filter (*) frequency
* Adjust signal amplification
(*) The Notch filter is a frequency dampener (from 100 to 250 Hz) that could cause a
resonance between the product and the acoustic guitar body.
This function is activated by pressing the dedicated button and in case of resonance,
you have to search the frequency to be dampened through its rotary control.
The Notch Filter doesn't act on DI OUT BALANCED, LINE OUT, STEREO OUT and
headphone but only on product's amplifi ed outlet.
