INTRODUCTION

General

Thank you for purchasing DAS iA series power amplifiers.

They have been designed with the lastest and most advanced Class D technology. As a result, a family of multi channel high efficiency, universal mains, amplifiers has been created for small/medium sized applications.

Features

- 2 or 4 channel models

- Class D, switching power supply

- Universal Mains regulated power supply

- Selectable Low or High Impedance operation

- Integrated limiter to prevent amplifier clip

- Integrated optional High Pass Filter at 80Hz

- Independent Volume controls per channel

- Power On led and dual color Signal/Clip leds per ouput channel

- Thermal protection

- Over current protection

- Built in DC protection

- Short Circuit protection

- Stereo (low impedance) and Bridge (high impedance) modes

- Ultra light weight

- Terminal block input&output connectors

If a consistent DC voltage is present at the output of the unit, the amplifier will enter a latching shutdown. Only a re-cycle of the mains voltage will restart the amplifier.

If the DC voltage on the amplifier output is due to an excessively high DC voltage pulse on the input of the amplifier the unit will attempt 3 times re-activate before latching shutdown.

- The iA series has a built-in current limitation to protect against overloading of the amplifier power stage. The current limitation will allow maximal current of typically

30Apeak during audio peaks without disabling the amplif ier. If an external clip-limiter has not been implemented or if an external clip-limiter is not capable of limiting the output current enough, (e.g. if a permanent short is loading the amplifier), the amplifier will disable to protect itself.

The current limit is depending on the temperature of the amplifier power stage. The higher the temperature – the lower the current limit for optimal protection of the amplifier.

- The iA series monitors their internal rail voltages to prevent overloading of internal components, and to ensure proper operation of the onboard amplifiers.

FRONT PANEL

A iA-404


A) Power Switch

Turns the amplifier on (“I” position) and off (“0” position).

When the amplifier is turned on the “power” LED will illuminate.

B) Power / Standby / Protection LED

A green color LED shows that the amplifier is ON.

A red color LED shows that the amplifier is in standby mode.

An orange color LED shows protection mode.

Protection mode may be triggered by:

- Overheating: Temperature protection will be enabled if either the internal power supply, transformer or one of the two amplif ier channels become too hot due to inadequate cooling. When the amplifier has cooled down the channel´s output will be activated and operation will continue.

- The iA series has a built-in DC protection feature. The DC protection will help to protect the loudspeaker from excess damage in case of an attempt to deliver a DC voltage out of the amplifier. This could happen either because the DC voltage on the input of the amplifier is too high or if the unit has an internal defect.

Overvoltage

In case voltage is too high on the internal rail voltages, the unit will Disable/Mute the amplifiers and temporarily shut down, to prevent damage of the internal components.

Undervoltage

In case that the amplifier internal rails drop to a very low level, the unit will Disable/Mute the two amplifier channels, to ensure correct operation of the amplifiers. Once the internal rail voltages rises to a normal level again, the amplifier channels will be reenabled.

C) Output channels Volume Controls

Volume levels for each channel can be adjusted by using the knobs on the front panel. Gain is maximum when the level of the rotary potentiometer is rotated fully clockwise.

D) Signal / Clip LED

These LEDs show the presence of signal at the amplifier´s inputs and is dependent on the position of the level control. In the event that the signal input level exceeds the amplifier´s input sensitivity the clip LEDs will light in organe (soft clip) or red (hard clip).

INSTALLATION

Racking

There are two 1U DIN high models (IA-402/404) and four

2U DIN high models (IA-1002/1004/1602/1604). All units are of a standard 19-inch rack mount width.

Four front panel mounting holes are provided for use with

M5 or M6 screws.

Amplif ier dimensions can be found on the “Line

Drawings” section in this manual.

Cooling

The amplifiers use a fan located on one of their side panels to maintain the unit under stable conditions.

The fans are inteligentlly managed by a micro controller varying their speed according to the needs.

Air inlets are located on one side of the amplifier. Do not block them at any time.

The side walls of the rack should be a minimum of 2 inches

(5 cm) from the amplifier sides. The back of the rack should be open.

Input cable connections

DAS Audio recommends using prebuilt or professionally wired balanced line (two-conductor plus shield)

2x0.22mm or 22-24 AWG cables to connect the amplifier balanced input by using the included 3.5mm pitch terminal block connectors.

Bridge mode - two 100/70V channels

DAS Audio recommends using prebuilt or professionally wired, high-quality, two-conductor, heavy gauge speaker wire. Speakers wires should be twisted cable, if possible. To prevent the possibility of short-circuits, the wires should be stripped back no greater than 6 mm (1/4 inch).

The maximum cable length of the line (100/70V) will be determined by the gauge (section) of the cable and the total power of the line.

A cable loss of less than 10% (around 1dB) would be a very good limit.

For the most common cable sizes we can find these values as a reference (copper cables):

Nominal AC voltage is 230V. Export versions may operate at 115V. keep in mind that the power supplies used are universal mains.

Connect your amplifier to the AC mains power source

(power outlet) with the supplied AC power cord. First, connect the IEC end of the cord set to the IEC connector on the amplifier; then, plug the other end of the cord set to the AC mains.

WARNING: The third prong of this connector (ground) is an important safety feature.

Do not attempt to disable this ground connection by using an adapter or other methods.

Current draw

The measured consumption at 1/3 of the power rating represents the worst case scenario in order to dimension the installation.

At 230V these are the values:

IA-402/404

: 1.52A (3A at 115V)

IA-1002/1004

: 1.75A (3.5A at 115V)

IA-1602/1604:

3A (6A at 115V)

USE

Switch ON/OFF

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 finally the amplifiers. If you have more than one amplifier switch them sequentially, one at a time.

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

Clip Led (also signal led)

The clip led should never be on continuously (red). The amplifiers integrate their own limiters to avoid sever amplifier clipping and reduce distortion, but the dynamic nature of music signals could make the amplifiers clip.

Thus at most, the clip light could be lit occasionally.

Level controls

The level rotary potentiometer is used for changing the input gain. With the levels at maximum the amplifier Gain is 30dB.

Although related to output power, it is not a direct representation of it. Thus, we can have the maximum output power with the level control at mid position and with a higher input signal level. Similarly, we may have the gain controls at maximum and not have maximum output if the input signal level is below amplifier´s input sensitivity.

Standby mode

To save energy, the unit is designed to go into standby mode after approximately 10minutes with no signal at any of the inputs. Return of signal to any input will reactivate the unit again.

TROUBLESHOOTING

PROBLEM

No sound from the unit

CAUSE

1 - The signal source is sending no signal.

2 - Input gain controls are at minimum position.

3 - Defective signal cables.

4 - Amplifier not plugged.

SOLUTION

1 - Check that the source is not muted and is sending signal to the unit.

2 - Check input gain controls. Put them at maximum level.

3 - Check that the cable from the source to the unit is connected correctly. Replace the cable if defective.

4 - Check the connections.

Full power cannot be obtained.

1 - The signal source does not have enough ouput level.

2 - Input gain controls are at very low volume.

1 - Use balanced outputs of a mixer.

Rise master ouput volume of the source.

2 - Set up level controls at higher positions.

Sound is distorted.

1-The mixer or signal source is distorting.

2 - The output level from the mixer is too high.

3 - Amplifier clip shown in the channel.

1-Turn down the mixer´s output and check no channels are distorting.

2 -Turn down the mixer´s output.

3 - Turn down input gain controls or lower input signal level.

Hum or buzz when a mixer is connected to the unit.

1-The console probably has unbalanced outputs. You may be using an incorrect unbalanced to balanced cable.

2 - The mixer and the powered speaker are not plugged into the same mains outlet.

3 - The audio signal cable is too long or too close to an AC cable.

1-Read the appendix of this manual to make a correct unbalanced to balanced cable.

2 - Connect the mixer and the unit to the same mains outlet.

3 - Use a cable that is as short as possible and/or move the audio signal cable away from mains cables.

Hum or buzz when using lighting controls in the same building.

1-The audio signal cable is too long or too close to the lighting cable.

2 - On a sound system with three phase AC, the lighting equipment and the unit are connected to the same phase.

1- Move the audio signal cable away from lighting cables.Try to find out at what point the noise is leaking into the system.

2 - Connect the sound system to a different phase than the lights. You may need the help of an electrician.

Low sound.

1 -The audio signal cable is defective.

2-The Level controls are not at maximum position.

3 - Low input signal level.

4 - Using speakers with transformer in stero mode.

1- Check cabling and replace them.

2 - Turn up level controls of the output channles.

3 - Turn up the level from the source.

4 - Change the amplifier´s mode from Stereo to Bridge (100/70V).

The ON led is indicating protection (Orange).

1 - The unit has activated the thermal protection.

2 - Short-Circuit.

3. Defective unit.

1 - Lower the input level and make sure the amplifier is being cooled correctly. Check that the fan is working and be sure that all the air inlets/outlets are not blocked.

2 - Check the cables, connectors and speakers connected.

3 - Contact an authorized dealer for service.

User’s Manual 35

ANNEX : Line connections: unbalanced and balanced

There are two basic ways to transport an audio signal with microphone or line level:

Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them.

Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono. 3 pin connector such as XLR (Cannon) may also carry unbalanced signals if one of the pins is unused.

Balanced line: Utilising a three conductor cable, one of them acts as a shield against electromagnetic noise and is the ground conductor. The other two have the same voltage with respect to the ground conductor but with opposite signs. The noise that cannot be rejected by the shield affects both signal conductors in the same way. At the device’s input the two signals get summed with opposite sign, so that noise is cancelled out while the programme signal doubles in level. Most professional audio devices use balanced inputs and outputs. Connectors that can carry balanced signal have three pins, such as XLR

(Cannon) and ¼” (6.35mm) stereo.

The graphs that follow show the recommended connection with different types of connectors to balanced processor or amplifier inputs. The connectors on the left-hand side come from a signal source, and the ones on the right hand side go to the inputs of the processor or amplifier. Note that on the unbalanced connectors on the left-hand side, two terminals are joined inside the connector. If hum occurs with balanced to balanced connections, try disconnecting the sleeve (ground) on the input connector. Note that the illustrations show what should be connected to what, but that pin locations on an actual XLR connector are different. Also, pin 2 hot is assumed on XLR connectors.
