This mark attracts the attention of the user to high voltages that are present inside the housing and that are of sufficient magnitude to cause a shock hazard.
This mark attracts the attention of the user to important instructions that are contained in the manual and that he should read and adhere to.

The unit has been certified CE. It is prohibited to make any changes to the unit. They would invalidate the CE certificate and their guarantee!d
NOTE:
To make sure that the unit will function normally, it must be used in rooms with a temperature between 5°C/41°F and 35°C/95°F.

Electric products must not be put into household waste. Please bring them to a recycling center. Ask your local authorities or your dealer about the way to proceed. The specifications are typical. The actual values can slightly change from one unit to the other. Specifications can be changed without prior notice.

Do not attempt to make any repairs yourself. This would invalidate your warranty. Do not make any changes to the unit. This would also invalidate your warranty. The warranty is not applicable in case of accidents or damages caused by inappropriate use or disrespect of the warnings contained in this manual. Vonyx cannot be held responsible for personal injuries caused by the disrespect of the safety recommendations and warnings. This is also applicable to all damages in whatever form.

FRONT PANEL

1. On/Off Switch.
   For switching the amplifier on and off. Always adjust the volume down to its minimum before switching this amplifier on.

2. Cooling Vents.
   Front to rear forced airflow.

3. Volume Controls.
   These controls adjust the volume level of both channels. Turn slightly to the left when the clip indicators (4) light up.

4. Signal indicators.
   Three orange LEDs indicate the amplifier’s output signal levels.

5. Clip Indication.
   These LEDs will light up when one or both channels are on max power. It can occur that these LEDs will be lit up now and then, but this is not a problem. But if it lights up continually you need to adjust the volume down, otherwise permanent damage to equipment might occur

6. Protect Indication.
   When at any given point, something damaging might occur to your amplifier, it will switch in protect mode. The amplifier will disconnect the point where the damage is about to occur and switch on the protection lead to indicate to you that something is wrong. The reasons might be Bad ventilation,
   A low impedance (< 4 Ohm), Defect fan(s), and A short circuit in cables.

7. Bridge Mode Indication.

8. Power Indication.
   This clear blue indicator will light when the amplifier is turned on.

REAR PANEL

1. 6.3mm Jack inputs.
   Two 6.3mm jack female input connectors for connecting a signal source (mixer etc.).

2. RCA inputs.
   Two RCA input connectors for connecting a signal source (mixer etc.).

3. Mode Switch.
   The amplifier can use 2 different modes: stereo & bridge.
   Choose one of these functions:
   Stereo mode: Standard left/right stereo mode.
   Bridge mode: This mode combines both amps on one channel which results in double power on this channel. Connects the signal to the left input channel and the output level can now be adjusted with the left volume control.

4. Ground Lift Switch.
   Allows circuit and chassis grounds to be separated in case of problems with earth loops (hum)..

5. 6.3mm Jack Outputs.
   Maximum load in stereo mode 4 Ohm per channel.

6. Speaker Outputs NL4.
   Maximum load in stereo mode 4 Ohm per channel.
   Pin +1 & +2 = + output,
   Pin -1 & -2 = – output

7. Binding Post Output Jacks.
   Maximum load in stereo mode 4 Ohm per channel. Maximum load in bridge mode 8 Ohm.

8. Mains Power Connector

9. Fuse
   This main fuse secures the amplifier and wires against defects. Replace this only with a fuse of the same type and value.

INSTALLATION

Connecting Output
Make sure the amplifier is turned off before you wire the system. Speakers can be connected using speaker NL4 plugs or bare wire for your binding post-output connectors. Using the guidelines below select the appropriate size of wire based on the distance between the amplifier and speaker.

Distance                    Wire Size
<10m                        1.5mm2

10m <20m            2.5mm2
20m <30m            4.0mm2

Setup operation mode

Amplifier can used in 2 modes:

Stereo operation

Set the mode selector (3) to the ‘stereo’ position. In this mode the amplifier have two in depended channels with their own inputs and volume controls.

Bridge operation

Set the mode selector (3) to the ‘bridged’ position.
This mode combines both amps on one channel which results in double power on this channel. Connects the signal to the A input channel and the output level can now be adjusted with the A volume control. Connect the speaker across the positive (+) output terminals. Do not use the negative (-) terminals when the amplifier is being operated in bridged mode.

NOTE:
Never connect a hot (+) output to ground or (-) output and never connect the hot (+) to other hot outputs!
Connect to mains power
Before plugging the unit in always make sure that the power supply matches the product specification voltage. First connect the IEC end of the cord set to the IEC connector on the amplifier then plug the other end of the cord set to the AC mains.
Please read the instructions below for reliable and problem-free use:

• Be sure all connections made are made in the correct way.
• Check if the connected speakers are compatible with the amplifier.
• Ensure there is adequate ventilation.
• Prevent exposure to moisture.
• Never plug speakers in/or out while in use, this can result in serious damage.

Specifications and design are subject to change without prior notice..
