QUICK START

1. Battery Switch [37] is set to Connect. (Battery Switch is set to Disconnect position to
preserve battery life for transit or storage.)

2. Make sure the SPEAKER VOLUME [3] control is down before you turn the POWER [38]
on.

3. Connect the input of your microphone to the MIC IN [18]. Or you can connect a ¼” line
input from an instrument [17]. You can also connect an additional mono or stereo [20].
All EQ knobs (21) should be set to 12 o’clock (FLAT EQ), Notch Filter knob (19) should
be also in the 12 o’clock. MUTE switch (13) and Phase switch (15) is out. EFX send level
(14) should be at minimum.

4. Turn on the POWER [38] switch, battery meter should be all GREEN (indicate battery is
fully charged)

5. EFX MIX knob (8) should be set to 12 o’clock. EFX should be bypassed until you are
ready to test EFX. Monitor EQ (6) should be set to 12 o’clock “FLAT EQ”

6. Turn up GAIN [12] until there is a solid green light showing “signal”[CHAN 1 meter] at
desired level, without a red “peak”[CHAN 1 meter] light, indicating too much signal.
Some MIC or INPUTs can distort the Speaker even with Gain Knob (12) at Minimum.
Press the PAD switch (16) to reduce the input signal level to avoid distortion if input
signal level is too high.

7. Adjust the SPEAKER VOLUME [3] to a comfortable level.

8. If you want to test Bluetooth® streaming, Connect device to Bluetooth® [40]

9. Recommended Monitor EQ (6) setting for Bluetooth playback - High and Mid (12 o’clock)
Low (1 - 2 o’clock)

10. Note if you are using an iPhone or iPad via Bluetooth®, set the volume on your device
about halfway. Maximum volume will distort. The Monitor Sigle (GREEN) LED is a good
indication of a good input level from your Bluetooth or AUX inputs.

11. Use Channel 1 for your Acoustic Guitar and Channel 2 for your vocal.

12. when you are getting a good sound without CHAN EQ or EFX, time to start playing with

the CHAN EQ and EFX - start with these recommended setting and adjust to achieve the

tone you prefer.

13. Acoustic Guitar EQ setting recommendations.
Low Volume - High (1 o’clock) Mid (12 o’clock) Low (1 o’clock)

14. Acoustic Guitar EQ setting recommendations.
Medium Volume - High (2 o’clock) Mid (11 o’clock) Low (2 o’clock)

15. Acoustic Guitar EQ setting recommendations.
High Volume - High (12 o’clock) Mid (9 o’clock) Low (12 o’clock)

16. Set you vocal EQ FLAT to start and ajdust EQ as you need.

17. Release the EFX mute switch (11)

18. Set EFX send level knob (14, 24, 31) on each channel to about 3 o’clock.

19. Select R2 - Reverb - Dark Cavern.

20. Turn EFX Parameter Knob (9) to 12 o’clock.

21. Turn Mix Knob (11) to 5 o’clock. Slowly turn it CCW to achieve the level of EFX you
prefer.

EAE BATTERY & RECHARGING INFORMATION

1. To fully charge a unit –

a. Set Battery Switch to “CONNECT”
b. Turn Power Switch OFF
c. Connect “AC” adaptor to Power Jack.
d. Blue “Charge” LED should be lit, Charge time can vary from 24 – 36 hours
depending on model and also surrounding temperature. In some case, Battery
will be 99% charged after 24-36 hours, but the charge light will remain on.

2. When unit is powered with “AC” adaptor, Battery Switch should be in “CONNECT”
position.

3. Battery Switch should be on “DISCONNECT” when unit is packed for transit or unit
is in storage. Make sure battery is fully charged before UNIT is put into storage. We
recommend fully charging the battery at least once each month.

4. SLA battery lifetime is typically 1 – 2 years depending on usage.

5. DO NOT OVERDRAIN the battery by leaving unit ON for a long period of time.

CAR ADAPTOR

• Unit can operate normally when plug into the Car Adaptor.

• Battery can also be charged by using the Car Adaptor.

• It is not recommedate that you leave the unit plugged in while car is not running.

HOW TO DEAL WITH ACOUSTIC FEEDBACK

Simply put, the annoying shrilling howl of growing and untamed feedback is the result of “in­phase” frequencies getting together and being reinforced by the sound system and environ­ment.

Phase Switch – since the purpose of the Phase Switch is to reverse the polarity, the rst line

of defense is to change the phase, which can sometimes be a cure all by itself. This has the

effect of changing the phase relationship between the amplied signal and live sound, which

can break up some “in-phase” reinforcing components. On the other hand, it’s preferred if we
can leave the phase set to provide the most natural and balanced sound.

Notch Filter – Another way to prevent “in-phase” reinforcement is to simply nd and “notch”

out the offending frequency. The approach is straight forward; with the Notch set to full “cut”
(counter clockwise), slowly rotate the Notch Frequency to align with and cancel the offensive
tone.

Phase and Notch – probably the most widely used approach is to start without the notch

lter engaged, and to bring up the gain and or volume to encourage feedback. Changing the

Phase will change the frequency of the feedback. Leave the Phase set to whichever setting
produces the higher pitched note.
Next, use the aforementioned Notch technique to hone in on and prevent the feedback. Keep

in mind, ghting feedback in this manner may or may not appeal to your taste in overall tone.

It’s certainly fair to experiment and try it the other way around, i.e., Phase switch to stop HF
tone and Notch to cutout the LF tone. After all, Live Sound is an Art and when it’s all said and
done tone is King.

ABOUT EQ AND PHASE SETTINGS

High – used to add sibilance and crispness to your sound, with the knob at 12:00, there is no

boost or cut to the high frequency content.

Mid – Helps control the clarity of your overall mix and should be adjusted to suit lower or

higher volume performance levels. Boosting the mids helps speech clarity and intelligibility at
lower volumes while cutting the mids produces a more natural sound at higher volumes. The
Mid frequency selection knob allows for a range extending from high LF to low HF. When set
to 12:00 the Mid frequency peak is around 1.2k Hz, with +/- 12dB of boost or cut depending
on the setting of the Mid knob. Here again, with Mid set to 12:00 the mid control is effectively
out of the circuit.

Low – In general, lower volumes can benet from LF boost to help bring out the bass at
these lower settings, but it is usually left at or even slightly cut for high playback levels.

Notch – When it comes to the mechanics, Notch ltering is very much like the adjustable
mid frequency described above. However, the frequency range is much lower, and the lter

itself is much tighter, hence the term “notch.” When used in “cut” mode, this is very effective
in managing feedback, which is explained in some detail in our Feedback section. However,
the notch can be set to cut or boost to allow for the full range of possibilities. Many times
feedback is not an issue, and the artist can take advantage of a particular notch setting to

effectively tweak a nal mix to accommodate specic room or instrumentation considerations.

Phase – Use the phase setting that best supports your overall sound and system integration
considerations. For example, Phase can be set to facilitate the best bass response at low
volumes, and it can also be effective as a feedback deterrent, which will be reviewed in our
Feedback section.

DIGITAL EFX

16 DIGITAL EFX PROGRAMS

•

• There are 16 total Digital EFX programs

• R1 to R10 - REVERB

• E1 and E2 - ECHO

• ER1 and ER2 - Echo and Reverb

• CHO - Chorus

• FLange - Flanger

•

• Program select Encoder (10) is for pro­gram change.

• Parameter knob (9) to change rate or
delay time for the program that is set.

• Mix knob (8) is to ne turn the amount of
EFX you want in output mix.

• EFX can be bypassed by Pressing the
bypass switch (9)

• EFX send levels for each channel is set
by on the rear panel ( 14, 24, and 31)
that correspond to each channel.

•

TIPS

• Distorted Sound

• 1) Check input level to make sure input Signal Light is in GREEN and not CLIP­PING RED. Reduce Input by turn down GAIN knob (12, 22, 30), input Gain can
also be reduced by Pressing “PAD” (16, 26), some MIC or PRE-AMPs have very
high output level, using the PAD switch for those devices and will help you re­duce the chance of distortion. Make sure all EQ knobs are set to Middle. (FLAT)

• 2) Check Monitor Signal Light is also GREEN and not Clipping. Reduce Speaker
Level by turning Monitor Knob (3), make sure EQ is set to middle (FLAT)

•

• No Sound

• 1) Check LED signal lights. Green means there is Signal on the input.

• 2) Make sure MIX knob is at 12 o’clock position.

• 3) Make sure Channel is un-muted.

• 4) Make sure +48V is on when using a Condenser Mic. Make sure to MUTE
when turning on +48V to prevent loud POP sound.

•

• Battery not Holding Charging

• 1) Power unit off and charge the unit for 24 hours with Battery switch in Connect­ed position. If problem still persist, contact [e-mail] for battery
replacement instructions.
