INTRODUCTION

General

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

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

FRONT PANEL

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-limi ter h as no t 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.

iA-404

A

INS TAL LAT IO N P OW ER AM PL IF IE R

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 amplif ier 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
tw o amp lif ie r cha nne ls be com e too h ot d ue 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 f rom
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 amplif ier 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 amplif ier´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.

Ampl if ier dimensions c an be f ou nd on t he “Li ne
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 amplif ier. 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
wi re d ba lan ce d li ne (t wo -co ndu ct or p lus shi eld )
2x0.22mm or 22-24 AWG cables to connect the amplifier
balanced input by using the included 3.5mm pitch
terminal block connectors.

Custom wiring should only be performed by qualif ied
personnel.

Speaker cable connections

5.08mm pitch,4 pin, terminal block connectors are used to
connect the speakers:

Select transformer tap position (10/20/30W)

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.

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 f ront. 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.
