Rear Panel Introduction

1. Input connection It is a balanced 3 core XLR female socket.

2. Status selection switch Push the switch to the position wanted. It is MONO mode at the left, STEREO in the middle and BRIDGE at the right. A ) STEREO mode STEREO is the most commonly used mode. Each channel will keep independent when it is at stereo mode. The volume control in front panel will work for relevant channel. B) MONO mode It is only the signal from CH 1 will be used under the MONO mode. The signals from all the output ends are the same and the volume control knobs will control the volume from relevant channels. C) BRIDGE mode It is only the signal from CH 1 will be used under this mode. The signals from the output ends will be the same and the phase will be contrast. All the output of the amplifier will be gathered to a output end. Since the amplifier is used as a mono equipment under the BRIDGE mode, the volume will be controlled by knob CH 1. The knob at CH 2 does not work at this mode. Please note, any end of the output cord can not be grounded under the BRIDGE mode because two ends of the cord are output. It is allowed the minimum impedance to be twice of the one under the normal stereo or mono mode.

3. Cool Air Vent It is the vent for cool air to flow into the amplifier. Pls do not block it with any stuff or place any thing in the front of the vent when the amplifier is at working status.

4. Alternating Input socket o be connected with suitable alternating electric power via the power cord.

Protection Functions

Digital power amplifier D series have full protection function against short circuit, direction current, over-load, over-heat and lower voltage. The protection will help to prevent possible damage to the equipment under the extreme situation.

1. Protection against short circuit

The protection circuit of the amplifier will monitor the current output situation at any time in operation. When short circuit happens or when the amplifier connects to the load with lower impedance, this protection function will start to work. The output of the amplifier will close and the protection circuit will detect the situation every few seconds automatically. When the short circuit or over-current disappear, the amplifier will resume to normal work situation.

The protection to very channel will work independently. When the amplifier is under STEREO mode or MONO mode, if short circuit happens at any one of the channels, this channel will be in protected situation, but the other channels will still work normally.

When the amplifier is under BRIDGE mode, every two channels of the amplifier will be connected to be one channel. So only one channel of two channel will be found output short circuit (including grounded short circuit) or over-current. Two channel will be in short circuit protection status.

NOTE : This amplifier is with full short-circuit protection. But long lasting short-circuit should be avoided by effort because long time short-circuit may cause over-heat to inside components of the amplifier and affect the using life of the amplifier.

2. Protection against direction current and secondary audio

When the amplifier is detected to find direct voltage or large range of secondary audio( lower than 20Hz) signals at the output end, the amplifier will be in the protection status. It will prevent damage to the speaker systems. At the same time, the STATUS indicator in front of the panel will turn from green to orange.

Front Panel Introduction

1. Power On/Off Switch PLS push down ON to turn on the power of the amplifier, push down OFF to turn off.

2. Air Vent It is the vent for the heated air to flow through from inside of the amplifier. Pls do not put any stuff inside or in the front of the vent to block the air flow. LED Indicators The user can know the working status of every channel with these LED indication lights. The LED lights includes three kinds of indicator as the following:

3. Working mode indicators MONO and BRIDGE When the mode selection switch in the rear panel is turned to BRIDGE or MONO, the relevant LED light in front panel will be lighten up at the same time. When it is at default working mode STEREO, these indicator lights will not shine.

4. Working status indicator STATUS When the power to the amplifier is turned on, the light STATUS will be lighten up. When the amplifier is at normal working status, the LED light STATUS will be lighten up in green color. When the amplifier is under protection and mute status, it will flash in RED color.

5. Signal indicators SIGNAL , CLIP and -10dB Even very small output can make SIGNAL to lighten up, it shows relevant channel is at work. When the light -10dB lightens up, it shows the output level is -10dB under the rated value. When CLIP lightens up, it shows the output level is higher than the rated value and the amplifier is at protection status.

6. Volume Control The Volume Control knob is used to adjust the volume. When it is turned at clockwise direction, the volume will be increased. Wen it is turned at anti-clockwise direction, the volume will be decrease. As to the 2 channel amplifier, when it is at STEREO mode or MONO mode, turn the volume control knobs at CH 1 and CH 2 to reach the wanted volume level. But when it is at BRIDGE mode, turn only the knobs at Ch1 to get the volume wanted. The knob at CH 2 does not work under BRIDGE mode.

3. Starting delay and mute

There is a soft start procedure inside the amplifier after turn the power switch to ON position. During this time, the amplifier will be in protection status. The STATUS light will turn to orange color. The amplifier will turn to normal work status after about 4 seconds and the STATUS light will turn from orange to green. All the other indicator lights will lighten up to show the live mode.

When turn the power switch to OFF position, the amplifier will be in shut off status. The light STATUS will turn from green to orange and turn off finally.

4. Protection against over-heat

When the temperature of the main cooling system of the amplifier is under 50 centi-degree, the cooling fan will run at very low speed. When it is between 50 and 70 centidegree,the cooling fan will run from slow speed via stepless speed change to full speed. When the temperature of the main cooling system reaches 90 centi-degree, the STATUS light will start to flash green and orange alternatively, which warns the user high temperature of the cooling system and to lower down the output intensity. .

NOTE

When the protection status happens at starting of the amplifier, it shows there maybe serious damage inside the amplifier. Pls shut off the power and take off the power cord . Then send the amplifier to the professional expert for maintenance.
