DPA-4300M

MULTI CHANNEL POWER AMPLIFIER

Features

High efficiency and low heat generation design using digital amp (OPT LESS) and SMPS

- Detachable and hot swappable module type for easy maintenance

- Individual power for each module. Amp operations of all channels will not be stopped due to single power failure.

- SLEEP mode minimizes the power consumption because by automatically switching to power saving mode.

- LCD and LED indicators which display the status of amp in each channel. Information of select switch located in the rear panel and operation status of amp can be checked easily.

- Remote site monitoring and control throughout contact point and TCP/IP. With contact point and TCP/IP, monitoring and control about various situations is possible.

- Bridge function. It supports Output Bridge between two channels to make maximum 600Wx2 output possible.

- CASCADE function. It distributes the input to other channel to make multi channel broadcastings possible with only one input.

- Support selectable two signal inputs. Use PGM (Normal and PRI (Priority) inputs. It can response to emergency broadcasting.

- Apply HPF, total three selects are possible. It can response to various PA speakers.

※OFF mode has two select types. (OFF/65Hz, factory setting is 65Hz)

- Apply protection circuits about over heat of amp (OTP), output short circuit (OCP), DC output (DCP) and power failure (PFP). It uses the protection circuit for errors which can occur during the installation and operation.

- Apply module socket contact point protection circuit. Attach and detach of the module is possible while amp is operated.

- PROT : it will be on if protection circuit is operated due to error in the channel.

- CLIP : it will be on if error occurs in the channel.

- SIGNAL : it will be on if input signal is detected in the channel.

- SLEEP : If input signal is not detected for certain times in the channel, it will be switched to the SLEEP mode and LED will be on. If input is detected again, it will be cleared.

- ST-BY : It will be on when the module is in Stand-by mode. It will be cleared if the module is available for broadcasting by pushing the power switch.

When switch is on, each module will be switched from ST-BY to broadcasting mode, and when it is off, it will be switched to ST-BY, Stand-By.

It displays the information about the operation and control of the module.

- DPA-4300M supports two inputs; normal (PGM) and priority (PRI) inputs.

- If volume up switch or volume down switch is pushed, PGM volume can be adjusted. Volume value will be

displayed on LCD.

- If volume up and down, switches are pushed together for 2 seconds, volume will be locked. Cleared if by

pushing for 2 seconds again.

- PGM MUTE will be set through GUI during TCP/IP communication.

※ PGM MUTE will be cleared if volume up/down switches are pushed or module power is off/on.

5. PRI VOLUME SELECTION SWITCH (CHECK IP)

- DPA-4300M supports two inputs; normal (PGM) and emergency (PRI). If volume up or down switch is

ushed while PRI switch is pushed, PRI volume can be adjusted. Volume value will be displayed on LCD.

- If PRI switch is pushed for 5 seconds, current IP value can be checked. It will be restored if PRI switch is

pushed again or after certain times.

- PRI input will be available if PRI SEL of rear side is on.

※ HPF will be set to 400Hz when inputting the PRI.

6. TEST SWITCH

It is the switch which can test the protection of module. Protection circuit will be operated while pushing it and speaker output will be off.

7. VENT

It is the ventilation air path to cool the inside temperature. Caution: Not to block the vent. Clean regularly.

※ Install the blank panel in the unused channel because failure due to foreign substance may occur.
