WELCOME • FEATURES

Thank you for choosing SLA 3000 series of professional amplifier. Please read this manual carefully and it contains important and helpful information to get the most out of your new product.
1.1 OPEN-PACKAGE TO INSPECT
Check your new amplifier out of the box. If damage is found, notify the dealer or the shipping company immediately. The consignee can claim for damage caused during transportation.

1.2 FEATURES:
a. Professional power amplifier with host of features and complete internal protection.
b. Class H design: SLA 3006, SLA 3008, SLA 3010 and SLA 3106
Class AB design: SLA 3003, SLA 3004 and SLA 3104
Class TD design: SLA 3013
c. Power supply design (models SLA 3003 – SLA 3010): Each channel of amplifier is driven by a separate power supply. This causes a lesser difference in output power between BCD mode (both channels driven) and SCD mode (single channel driven) as compared to amplifiers using single power supply for both channels. It also reduces crosstalk at higher frequencies. Moreover, for the Class H amplifiers, the power supply has multiple supply rails which are selected by a real-time control circuit that monitors the output continuously. The lowest rail voltage is always selected for a certain output so that power dissipation is minimised.
d. Power output stage: The output stage employs a large number of matched complementary devices in parallel having linear transfer characteristic for low distortion and high SOA guaranteeing safe operation at elevated power levels.
e. Built-in intelligent limiter: There is a built-in limiter for each channel which works by sensing the output and automatically limits the input signal in case of excessive clipping or overheat (dynamic SOA control)
f. Heavy-duty Binding post and professional twist-lock connectors for speaker connection.
g. Exhaustive protection: The power amplifier provides many different types of protection including DC protection, internal fault protection, input overload protection, RF interference filter, output short circuit protection, high frequency overload protection, overheat protection of heat sink and transformer and mains input over current protection.
h. Cooling: There is heat tunnel formed by special-design copper heat sinks and high-speed fans. The tunnel arrangement enhances the heat dissipation and isolates the rest of the amplifier from the heat sinks thereby providing a dust-seal. Dust filter on the front reduces ingress of dust.
i. Heavy-duty mains cable with 3 pin 15A plug is built into the unit to prevent loose connection caused by detachable mains cable.
j. Heavy-duty steel chassis with handles allow the amplifier to be slid in or out of a rack.

OPERATION

4.1 POWER SUPPLY REQUIREMENTS
Each amplifier has a different output power rating, please refer to the printing on rear panel. Make sure the supply voltage is correct before connecting the amplifier. Connecting the amplifier to a mismatched AC voltage can cause damage to the amplifier.
The power supply requirement is: 230VAC/50 Hz
4.2 COOLING SYSTEM AND REQUIREMENTS
The amplifier uses forced air cooling. Cool air is sucked in through two ventilation pockets on front panel by fans mounted in the heat tunnel. This cools the heat sink. The “intelligent” variable speed DC fan is controlled by a thermal circuit which senses the temperature of the heat sink. When the amplifier is turned on, the fan speed increases for a short time and then slows down; this indicates that the thermal circuit is working properly. The fan speed will vary with the heat sink temperature. At full power, the fan switches to high speed to cool the heat sinks. If the heat sink temperature exceeds the maximum allowable temperature, the amplifier will shut down.
NOTE: To ensure optimum cooling conditions, check that the front and rear of the amplifier is unobstructed and allows free flow of air.
4.3 INPUT CONNECTION
Connect the balanced output of your source equipment to this input with a 3 pin XLR female to XLR male cable. For details please refer to the section on back panel above. To loop the input to a second amplifier, connect the input of the second amplifier to the LINK terminal.
