Clip LED (D)

When the output signal distortion of the corresponding channel exceeds 1%, the LED will light, due to the signal level being is too high.

Protection LED (E)

When circuit protection works, the LED will light, especially when the heat-sinks overheat or detect the DC voltage in the amplifier. Also, turn on the amplifier and within three seconds, the amplifier is ready to work, the LED will shine. When startup is complete or the problem is removed, the LED will extinguish, and resume working normally.

SIG

Signal LED (F)

When there is an input signal, the LED will light. If not, please check the gain settings. If necessary, the gain can be increased. Check the input connection and signal audio source. If the Clip LED shines a little or shows no signal, check the output wire whether it is in short-circuit or not.

Cooling air grilles (G)

Fan cooling permits airflow through the most vital parts of the amplifier. Since the airflow finds its way out through these grilles, keep them as clean and dust-free as possible to assure proper cooling.

Speaker outputs (A)

Connecting speakers to each output it is done through Speakon-type connectors whose pin assignments are:

Channel 1 (stereo and parallel modes) :

Channel 2 (stereo and parallel modes) :

Channel 1 (bridge mode) : pin +1 = positive / pin -1 = negative pin +1 = positive / pin -1 = negative pin +1 = positive / pin +2 = negative

Inputs (B)

CH1 and CH2 are directly connected to the mixer, the input and output connectors of the respective channel are put together, to provide fixed connection, and no need to consider the power switch setting.

The nominal input impedance of 20kohms and 10kohms balanced mode in non-balanced mode.

The pin assignment is according to the standard AES14-1992 (ANSI S4.48-1992):

Pin 1 (XLR) : GND (Ground)

Pin 2 (XLR) : (+) Non-inverted signal

Pin 3 (XLR) : (-) Inverted signal

BRIDGE mode makes CH1 input signals from the BRIDGE output socket, output must use CH1 volume control to adjust the volume.

PARALLEL mode makes CH1 input signal by CH1 and CH2 output socket output.

The input socket of Ch2 has no effect. Channel's volume can be adjusted independently.

Sensitivity mode (D)

This switch allows to set the sensitivity between 0.775V or 1.4V.

Circuit breaker (E):

When amplifier is overloaded (caused by the small load impedance of the amplifier or the continuous input signal), the button of the circuit breaker will upspring immediately, and will be cutoff power automatically to protect the amplifier. You must exclude overload condition, and then press the button of the circuit breaker, and the power amplifier will resume to normal operation.

Power outlet (F)

The amplifier is provided with a socket IEC320-C14. When using the amplifier, one should check whether the selected voltage is correct or not. If the voltage is wrong, it could damage the amplifier. Please ensure that the device is connected to the power supply with ground to use.

Cooling air outlet grilles (G )

Fan cooling permits airflow through the most vital parts of the amplifier. Since the airflow finds its way out through these grilles, keep them as clean and dust-free as possible to assure proper cooling.

INSTALLATION

Racking

All amplifiers are 19-inch rack mount width and are 2U DIN in height.

Four front-panel mounting holes are provided for use with M5 or M6 or 1/4” screws. To avoid bending the chassis in rack mounting applications where the rack will be transported, mount the amplifiers to the back of the rack using the rear mounting holes. Alternatively, place the bottom amplifier against the base of the rack and pile the amplifiers with no clearance in between.

A fan cools the aluminum heat sinks from front to back.

Fan cooling permits airflow through the most vital parts of the amplifier.

When mounting the unit onto a 19-inch rack, a rack cooling system is not required, since the air is exhausted out through the front grille.

However, the rack must not be sealed, and it should at least have a large enough ventilation grille to allow air into the rack.

ON / OFF

The main power switch is a push button that turns the amplifier on/off.

When the amplifier turns on, the power LED and protection LED are illuminated. After a few seconds, when the start is finished the

PROTECTION LED will go out and the amplifier will be ready for use.

To turn the amplifier off, push the button. At that moment the main power supply voltage and the secondary power supply voltage will turn off internally.

Switch your sound system on from back to front. Thus, switch on the amplifiers last on your sound system. Switch sound sources (CDs, turntables) first, then your mixer, then your processors and crossovers and finally the amplifiers. If you have more than one amplifier, switch them on sequentially, one at a time or use a sequencer.

Follow the reverse order when switching off, and switch off the amplifiers before any other element on your sound system.

Clip LED

The clip LED should never be on continuously.

This will distort the signal and may damage the speakers. In fact, severe clipping is an easy way of burning a speaker's voice coil.

The amplifiers feature an automatic limiting system that impedes prolonged saturation, but the dynamic nature of music signals stops it from being a brick wall protection. Thus at most, the clip light could be lit occasionally.

Input connection

A balanced connection is recommended with

XLR connectors, but an unbalanced connection can also be used.

Speaker connection

Connect speakers at one or two output

Speakon connectors. See the rear panel instructions.

Speakon connectors offer quick connection for portable applications. To enable a Speakon connection, plug the male connector into the outlet and rotate it clockwise. It will then lock into place and be ready for use.

Mains connection

Should check whether the selected voltage is correct or not. If the voltage is wrong, it could damage the amplifier.

The230 V AC version has a nominal voltage plus minus 10%, i.e., the amplifier can operate from 207 V to 253 V AC.

Similarly, the 115 V AC version has a nominal voltage plus minus 10%, i.e., the amplifier can operate from 103 V to 127 V AC.

In both cases the operating voltage will be indicated on the back panel.

Level controls

The level rotary potentiometer is used for changing the input gain. Although related to output power, it is not a direct representation of it. Thus, we can have maximum output power with the gain at mid position. Similarly, we may have the gain controls at maximum and not have maximum output if our source signal is not strong enough.

One way to use the volume controls is to set them such that when the mixer's faders are at their maximum level, we are just below clipping level on the amplifier or clipping very occasionally.
