DECLARATION OF ORIGIN

All Vision products are made in the People's Republic of China (PRC).

USE ONLY DOMESTIC AC OUTLETS

Connecting the unit to an outlet supplying a higher voltage may create a fire hazard.

HANDLE THE POWER CORD WITH CARE

Do not disconnect the plug from the AC outlet by pulling the cord; always pull the plug itself. Pulling the cord may damage it. If you do not intend to use your unit for any considerable length of time, unplug the unit. Do not place furniture or other heavy objects on the cord, and try to avoid dropping heavy objects on it. Do not tie a knot in the power cord. Not only could the cord be damaged, but a short circuit could also be caused with a consequent fire hazard.

PLACE OF INSTALLATION

Avoid installing this product under the following conditions:

• Moist or humid places
• Places exposed to direct sunlight or close to heating equipment
• Extremely cold locations
• Places subject to excessive vibration or dust
  Poorly ventilated places

Do not expose this product to dripping or splashing. DO NOT PLACE OBJECTS FILLED WITH LIQUIDS ON OR NEAR THIS PRODUCT!

MOVING THE UNIT

Before moving the unit, be sure to pull out the power cord from the AC outlet and disconnect the interconnection cords with other units.

WARNING SIGNS

If you detect an abnormal smell or smoke, turn this product off immediately and unplug the power cord. Contact your reseller or Vision.

PACKAGING

Save all packing material. It is essential for shipping in the event the unit ever needs repair.

IF ORIGINAL PACKAGING IS NOT USED TO RETURN THE UNIT TO THE SERVICE CENTRE, DAMAGE IN TRANSIT WILL NOT BE COVERED BY WARRANTY.

WATTS

The most consistent standards for measuring watts are "Program Power" and "RMS" because these measure average sustained levels.

Amplifier power output changes depending on how many loudspeakers are connected. Professional manufacturers typically quote output based on 8 ohms. Less reputable manufacturers quote at 4 ohms to make their product seem more powerful.

This amplifier has an output of:

2 × 25w (sometimes referred to as 50w ) @ 8 ohms (two loudspeakers connected)
2 x 50w (sometimes referred to as 100w) @ 4 ohms (four loudspeakers connected)

INSTALLATION

1. CONNECT INPUTS AND OUTPUTS Up to two pairs of loudspeakers can be connected. If speaker cable provided is not long enough use unshielded speaker cable with gauge of 0.75mm or higher.

NOTE 1: The warranty will be void if you use shielded cable

NOTE 2: This is a low-impedance digital amplifier. Do not connect '100v line' speakers (normally any speakers with "t" in their part code)

1. CONNECT POWER The amplifier will turn on when power is plugged in the first time.
2. TURN POWER ON Then select input and adjust volume as required.

Should it become overloaded it will shut down to protect itself. Return operating conditions to safe levels and restart amplifier.

When input signal drops below a threshold for an extended period the amp will put itself into standby. When it senses signal it will turn itself back on.

MICROPHONE INPUT

1. The microphone input provides "Phantom Power" (24v) for condenser microphones such as lectern or boundary (PZM) microphones.
   NOTE: Ensure the microphone volume is turned down when connecting microphones.
2. The microphone volume can be adjusted independently of the line-level inputs.
3. Keep microphone away from loudspeakers to avoid feedback.

DISABLE PHANTOM POWER

Buzzes or hums may be caused by Phantom Power. Disable by REMOVING jumper shown:

BLUETOOTH INPUT

DEFAULTPIN:0000

When amp is turned on or when Bluetooth selected, the Bluetooth radio will be in pairing mode for 10 minutes. The Blue LED will flash while in pairing mode, then stay on when paired.

If "Bluetooth Priority" is on the amplifier will automatically switch to the Bluetooth source when a device is paired.

CHANGE BLUETOOTH DEVICE NAME AND PIN

1. DOWNLOAD AND INSTALL BLUESUITE SOFTWARE (WINDOWS ONLY) FROM https://visionaudiovisual.com/techaudio/av-1800/
2. PAIR PHONE TO AMPLIFIER
3. PRESS BUTTON ON REAR OF AMP Release when Blue LED on front turns off
4. CONNECT PC TO AMP WITH USB CABLE (NOT INCLUDED)
5. RUN PSTool APPLICATION. Select USB\csr0 port as below

NOTE: if port is not showing load drivers manually from C: |Program Files (x86)|CSR|BlueSuite 2.6.4|drivers

6. TYPE "NAME" IN FILTER Adjust then select Set

7. TYPE "FIX" IN FILTER The current PIN in this example is shown below:

Adjust PIN (last digit of each group), then press Set and Reset BC.

TROUBLESHOOTING

If your system is not operating properly, please refer to the following information. If the problem persists, disconnect from power and contact your AV reseller immediately.

Problem	Correction
No Sound	·Turn off and check connections. ·Check output level from sources. For example, laptop volume.
Microphone quiet	·Some microphones have a gain switch. Consult the manual.
No Power light	·Check power connections ·Abnormal load. Turn power off, disconnect some speakers and test again
Distortion	·Input gain too high ·Volume too high ·Loudspeakers may be worn or damaged
Feedback	·Turn microphone down, or move away from speakers
Sound only coming out one side	·Turn off and switch output connections. If the side changes the amplifier is okay – the fault is with the speakers. ·Switch input connections and check input cabling.
