ELITE ACOUSTICS A1-8 Compact Lithium Battery Powered Acoustic Amplifier

Product Information

• The Elite Acoustics Engineering A1-8 is a compact lithium battery-powered acoustic amplifier with three channels, a mixer, and 16 digital effects. It is designed to provide high-quality sound amplification for acoustic instruments.
• The amplifier features a speaker volume control, monitor output controls, main output with XLR output, and a battery switch to preserve battery life.
• It also has a power LED indicator to show when the unit is on, a +48V LED indicator to indicate phantom power, and a monitor equalizer to adjust the speaker’s high, mid, and low-frequency response.
• The A1-8 amplifier is equipped with various input options, including instrument inputs (1/4 TRS), balanced mic inputs (XLR), and an aux input (1/8 jack) for connecting audio sources like MP3/CD players. It also has a +9VDC output that can be used to power compatible digital mixers.
• The amplifier comes with 16 digital effects, including echo, ambience, hall, room, plate, chorus, flange, and more. These effects can be controlled using the effects controls on the top panel of the amplifier.
• The A1-8 amplifier is designed, assembled, and tested in California, USA by Elite Acoustics.

Product Usage Instructions

1. Before using the amplifier, ensure that the battery switch is set to “Connect” to preserve battery life.
2. Make sure the speaker volume control is turned down before turning on the power switch.
3. Connect your instrument to the appropriate input (instrument input or balanced mic input).
4. If desired, you can connect an additional mono or stereo source to the aux input.
5. Turn on the power switch to activate the amplifier.
6. Turn on your source signal(s) and adjust the volume on the source signal for normal operation.
7. Adjust the level control until you see a solid green light indicating a signal at the desired level. Avoid a red peak light, which indicates too much signal.
8. Adjust the speaker volume control to a comfortable listening level.

Note: The amplifier’s features and specifications are subject to change without notice. Please refer to the user manual for the most up-to-date information.

CONNECTING

CONNECTING TO ANOTHER SPEAKER FOR STEREO

The Monitor Right Output (33) allows you to add a secondary active monitor while preserving the stereo image. The Monitor unit will play the Left Channel content and the secondary monitor will play the Right Channel. If stereo imaging is not desired, simply engage the Mono button on the A4-8’s top panel. Note that the Monitor Right Output (33) will not drive a passive speaker; it is a Line-level output that can drive amplifiers or active monitor systems. Connect Master Speaker Right output (33) to Secondary Speaker Chan 3/4 Line input (32). Set Secondary Speaker Gain (30) to 3 0’clock. Then set Secondary Monitor Level (3) to balance the Left (Master speaker) and Right (Secondary speaker) channels. EQ on Secondary Speaker should be FLAT and EFX (11) should be bypassed.

CONNECTING TO ANOTHER ACTIVE SPEAKER (HOUSE PA) FROM DIRECT OUTPUTS OR MAIN MIX OUTPUTS
The XLR output jacks can be used for MAIN MIX outputs (seperate from the Monitor Speaker Output) or Direct Outputs for Chan 1 “Left” (35) and Chan 2 “Right” (35) with Level Control. Switch (34) control Main (Switch Out) or Direct Out (Switch pressed in).

EAE BATTERY & RECHARGING INFORMATION

1. To fully charge a unit –
   • a. Turn Power Switch OFF
   • b. Connect “AC” adaptor to Power Jack.
   • c. RED/GREEN bi-color “Charge” LED should be lit, Charge time is about 5-6 hours.
2. Lithium Iron Phosphate (LifePO4) battery lifetime is typically 4 – 5 years depending on usage.
3. Recharge Battery every month if not in use.

FOR MAXIMUM BATTERY LIFE

• Battery TYPE – LifePO4
• Battery METER indicators –
• NORMAL – (LED1/3) GREEN ON
• LOW — (LED1/3) GREEN ON, (LED2/4) (Bi-Color) RED – ON less then (about 10% – 25%)
• LOW – (LED1/3) GREEN OFF, (LED2/4) (Bi-color) RED ON (less then 10%)
• FULLY CHARGED. – (LED2/4) (Bi-color) GREEN LED ON
• CHARGING – (LED 5) (Bi-color) RED/GREEN LEDs ON. (will turn off when Fully Charged)
• For Maximum Battery Life
• Recharge when battery is low.
• Drain & recharge battery at least once a month
• Do not leave power switch in the “ON” position when it is not in use.
• Keep unit in a cool, dry place away from extreme temperatures
• Do not service, modify, or replace the battery
• If the battery fails to charge, contact Elite Acoustics

ABOUT EQ 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 benefit from LF boost to help bring out the bass at these lower settings, but it is usually left flat or even slightly cut for high playback levels.

DIGITAL EFX

• R1 – Bright Cavern
• R2 – Dark Cavern
• R3 – Bright Hall
• R4 – Dark Hall
• R5 – Bright Room
• R6 – Dark Room
• R7 – Bright Plate
• R8 – Dark Plate

• R10 – Ambience2
• E1 – Echo
• E2 – Repeat Echo
• ER1 – Echo/Rev1
• ER2 – Echo/Rev2
• CHO – Chorus
• Flange – Flange

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 the rate or delay time for the program that is set.
• Mix knob (8) is to fine-turn the amount of EFX you want in the output mix.
• EFX can be bypassed by Pressing the bypass switch (9)
• EFX send levels for each channel are set on the rear panel ( 14, 24, and 31) that correspond to each channel.

TIPS

Distorted Sound

1. Check the input level to make sure the input Signal Light is in GREEN and not CLIPPING RED. Reduce Input by turning down the GAIN knob (12, 19). 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 a Signal on the input.
2. Make sure the MIX knob is at the 12 o’clock position.
3. Make sure the Channel is unmuted.
4. Make sure +48V is on when using a Condenser Mic. Make sure to MUTE when turning on +48V to prevent a loud POP sound.

Battery not Holding Charging

1. Power unit off and charge the unit for 24 hours. If the problem still persists, contact support@eliteacoustics.com. for battery replacement instructions.
