Frequently Asked Questions - C2- 800 BEGLEC

How do I connect the amplifier in bridge (mono) mode?

Turn off the amplifier. Connect the input only to channel 1 (left). Connect the speaker between the red binding posts: red terminal channel 1 (signal +) and red terminal channel 2 (signal -). Minimum impedance 8 Ω. Set the mode switch to BRIDGE then turn on.

What is the recommended input sensitivity for a JB Systems mixing console?

Use the 1.4 V position of the input sensitivity selector. This corresponds to a gain of 26 dB.

What to do if the protection LED (yellow) lights up?

The yellow LED lights up in case of a fault or if the temperature exceeds 85 °C. Check ventilation and connections. If it stays on, turn off the amplifier and contact your dealer.

Can I use an unbalanced Jack input?

Yes, use a mono jack. Tip = signal, Sleeve = ground. For a balanced signal, use a stereo jack: Tip = signal +, Ring = signal -, Sleeve = ground.

How to clean the dust filters?

The filters are located behind the front panel. Use a vacuum cleaner to clean them regularly. Never use water.

What is the maximum output power in stereo mode on 4 ohms?

The C2-800 model delivers 780 W + 780 W in stereo at 4 ohms.

How to replace the fuse?

Unplug the amplifier. Open the fuse compartment and replace it with a fuse of the same type and rating (indicated near the fuse holder). If the problem persists, consult a technician.

What does the red 'Clip' LED illuminated continuously mean?

A continuously lit Clip LED indicates a short circuit at the output. Turn off the amplifier and check the speaker connections.

Can I use the amplifier in parallel mode?

Yes, in parallel mode, the input is connected to the left channel only, and both channels feed the same speakers (connected normally). Set the switch to 'Parallel'.

What is the cooling type of the amplifier?

The C2-800 is equipped with a variable speed fan for cooling adapted to the load.

USER MANUAL C2- 800 BEGLEC

The PS series amplifiers are high quality and performance amplifiers. To get the maximum result, it features a servo system, power supply and a fan with adjusted speed.

The main features include:

• XLR and 1/4' jack balanced input
- Input sensitivity switch
• Output: Speacon and speaker terminals
- Stereo, bridge and parallel switch
- Soft start
• Perfect protection system for the speakers
• Thermal cut off (85°C protection)
- Current limiter

2. Precautions

• Use an adequate power source.
• Do not turn on several amplifiers at the same time.
• Do not allow that the ventilation holes in the front or in the back of the amplifier are blocked in any way.
• Input level controls are present on each channel.
  • Output can use speacon or binding posts.
• Please check carefully if the mode switch is in the correct position: stereo, bridge or parallel.
• Clean the amplifier regularly. Especially the dustfilters located behind the front panel should be cleaned regularly.
• Use a vacuumcleaner to remove dust inside the amplifier. Never use water.
  • In case of a defect, contact your dealer.

A. Front Panel

JBSYSTEMS Power SUP PROTEST 8 134 ON BNDGE POWER STANDARD PROTEST 6 10 SUP PROTEST 7 9 2 5 4 1 6 4 3 8 10

1. Power ON/OFF

With this switch, you turn the amplifier on. You will note a brief delay in the switching on, due to the soft start.

2/3. Input Level Control

With these rotary VR's, you can adjust the input level of each side. In bridge or parallel mode, only the left VR is active.

4. Power ON Indicator (green)

Indicates that the amplifier is on.

5. Bridge Mode Indicator (green)

Indicates that the amplifier is working in bridge mode. In this case only the left channel needs an input signal.

6. Parallel Mode Inidicator (green)

Indicates that the amplifier is running in parallel mode. The input signal must only be applied to the left channel.

7/8. Protection LED (yellow)

The leds light up when the amplifier is overheated (thermal protection) or when something is wrong with the amplifier.

9/10. Peak Level (clip) Indicator (red)

These leds will light up in two situations:

a. When the output signal has reached its maximum level, the LED will light. This goes with a distortion of the audio signal. When this occurs, reduce the input level.

b. When you have an input signal and the clip led lights continuously, it means that you have a short circuit on the output. Please turn of the amplifier and check out the problem on the load.

1/5. 1/4' Jack Input Connectors

You can use a balanced or unbalanced input signal.

• Unbalanced: use a mono jack. Tip=signal, Sleeve=ground.
• Balanced: use a stereo jack. Tip=signal+, Ring=signal-, Sleeve=ground.

2/4. XLR Input Connectors

You can use a balanced or unbalanced input signal.

• Unbalanced: Pin 1=ground, Pin 2=signal, Pin 3=ground=pin 1.
  • Balanced: Pin 1=ground, Pin 2=signal+, Pin 3=signal-.

3. Input Sensitivity Switch

The position of this switch is very important and depends on the output level of your preamplifier. There are 3 positions:

• Full power output at 0,77V input level
• 26 dB gain of the input signal
- Full power output at 1,4V input level. Use this position with JBSystems mixers.

6. Mode Selector

You can select between stereo mode, bridge mode or parallel mode.

• When you use stereo mode, you have to connect the input and output of both channels.
• When you use bridge mode, the input signal must be applied to the left channel only.
• When you use parallel mode, the input signal must be applied to the left channel only.

7. Ground Lift Switch

Setting this switch to the position "left" breaks the ground loop between the amplifier and the chassis ground of various components.

8/11. Speacon Output

When you work in stereo mode, you can use the speacon for connecting your speakers.

The connections are:

1+ and 2+ : signal

1- and 2- : ground

9/10. Binding Posts

In stereo mode:

Red = signal

Black = ground

12. Power Cord Socket and Fuse

When the fuse is broken, replace by the same type and value.

4. Operation in bridge mode and parallel mode

A. Bridge Mode

• Turn the amplifier off
• Connect the input to CH1 (left) only
• Connect your speaker system across the red terminals
  ■ Red terminal CH1: signal +
  ■ Red terminal CH2: signal – (ground)

- The minimum impedance of your speaker system should be 8 Ohm

- Set the mode switch on BRIDGE

- Turn the amplifier on

B. Parallel Mode

• Turn the amplifier off
• Connect the input to CH1 (left) only
• Connect your speakers in the normal way, as you should do in stereo mode
• Set the mode switch on PARALLEL

• Turn on the amplifier
