INTRODUCTION

Congratulations! You have just purchased a new, state of the art 70.7v Digital Power Amplifier which will provide you with many years

of service. The DS1628 soundmasking amplifier utilizes a new high speed switching power supply and a modified class D output

topology. The amplifier will deliver 80 watts @ 70.7 volts of power per channel and is offered in a two channel configuration . This

remarkable performance comes in a compact enclosure occupying just one rack space and weighing only 7 lbs.

The DS1628 is primarily convection cooled. When installed in an electronic equipment rack ventilation space should be left ab ove and

below the amplifier. If the amplifier is to be used freestanding the provided rubber feet must be used to allow air flow to the bottom of

the DS1628. Under no circumstances should the amplifier be placed directly on carpeting or similar surfaces.

In addition to being convection cooled the DS1628 is protected by multiple temperature sensing circuits and additional cooling can be

provided by a high speed fan, which exhausts warm air from the left side panel. To allow proper ventilation, an un-obstructed

clearance of at least 0.75" must be maintained along the left side panel of the DS1628.

In the event the internal temperature of the DS1628 reaches 85 degrees centigrade, a protection circuit will shut down the power supply

until the amplifier cools down.

DS1628 FRONT PANEL

Power Indicator: This red LED remains lit when AC power is applied to the unit.

Signal / Clip Indicator: This 2-color LED indicates the signal level for the amplifier. When the LED is green, the amplifier has signal .

During normal usage, it is normal for the green LED "flicker" due to the random nat ure of soundmasking. When the LED is red, the

amplifier signal is clipping (maximum power). CAUTION: Signal levels should be adjusted to avoid clipping. Clipping can cause

severe distortion, over-temperature conditions, and even loudspeaker damage.

REAR PANEL

Input: This plug-in barrier strip provides the line-level input to the amplifier. For unbalanced input, wire high (+) and ground (▼). For

balanced input, wire high (+), low (-), and ground (▼).

Level: This screw-driver adjustable control determines the level of input signals allowed into the amplifier. Level provides a gain range

from 'off' (min.) to 'unity' (max.). For best performance, first adjust the source signals for optimum (maximum) levels, and then adjust the

amplifier level control for the desired volume.
