INTRODUCTION General information Amplifier features (Models: DR-15A DR-15AW and DR-108A) Thank you for purchasing D.A.S. Audio S.A. products. The DR series represents more than 30 years of expertise in transducer and enclosure design, achieving a system that utilises the most advanced sound reinforcement technology to deliver outstanding audio performance and maximum reliability. This manual contains the required information to make the best use of the system you have purchased.
AMPLIFIER DESCRIPTION B) MIC: Controls the level for the MIC (microphone) input. C) LEVEL: Controls the system's main level, acting on the microphone and line mix. D) LINE OUT : This 1/4” (6.35 mm) line output is used to send the built-in mixer output signal. As many units as required can be daisy-chained. It can also be used to feed a power amplifier. It is located before the main LEVEL control, and thus this control can be used as the level control for each system within a group of daisy-chained systems.
DR-112A and DR-115A amplifier A) MIC/LINE : Switches between microphone and line modes. The indicator light on the left hand side of the switch is lit when the microphone mode is activated. B) LOW CUT: Switches a 100 Hz high-pass filter on and off. C) LEVEL: Controls the level of the system. D) LOOP THRU : Used for paralleling several units, which will share the same input. This balanced connector has three pins for which pin assignments are as follows : 1 = GND (Ground). 2 = (+) non-inverted signal.
CONNECTIONS Powered sub-woofer reinforcement connection Signal wiring 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. Electro-magnetic interference can get added to the signal as undesired noise. Connectors that carry un-balanced signals have two pins, such as RCA (Phono) and 1/4” (6.35 mm, often referred to as jack) mono.
INSTALLATION Placement Place the speakers ahead of the microphones. Feedback (howling) occurs when the microphones pick up the sound that comes out of the speakers and feeds it back to the system. Feedback can cause damage to your unit. If space is limited, direct the speakers towards areas where there are no microphones to minimise feedback. When using a turntable, place the speakers far from the turntables.
USE Switch ON/OFF Overheating A sound system should be switched on sequentially. Switch on the self-powered unit last in your sound system. Switch on the sound sources such as CD players or turntables, then the mixer and finally the self-powered unit. If you have several units, it is recommended that you switch them on sequentially one at a time. Follow the inverse order when switching off, turning self-powered units off before any other element in the sound system.
TROUBLESHOOTING PROBLEM No sound from the unit. The power on LED indicator (on the front of the unit) does not light up when the power switch is at the on (“|”) position. CAUSE 1 - Bad or loose AC connection to the unit or the mains outlet. 2 - Faulty AC cable. 3 - Blown Fuse. No sound from the unit. The power on LED indicator (on the front of the unit) lights up when the power switch is at the on (“|”) position. 1 - The channel (MIC or LINE) or the main (LEVEL) volume controls are set too low.
PROBLEM Hum or buzz when a mixer is connected to the unit. Hum or buzz when a CD, cassette, VCR or keyboard is connected to the unit. CAUSE 1 - The console probably has unbalanced outputs. You may be using an incorrect un-balanced to balanced cable. 1 – Read the Appendix A of this manual to make a correct un-balanced to balanced cable. 2 - The mixer and powered speaker are not plugged into the same mains outlet. 2 – Connect the mixer and the powered speaker to the same mains outlet.

APPENDIX: 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.
