Introduction Thank you for purchasing the Samson Auro professional, powered loudspeaker. The Auro D412 and D415 are compact and powerful speaker cabinets featuring 400 watts of bi-amped onboard power. The Auro D412 and D415, respectively, feature 12” and 15” heavy-duty, long-excursion woofers, as well as 1.34” titanium compression drivers on 1” throat wide dispersion horns. The speaker cabinets provide both XLR and ¼” phone jacks that handle microphone or line level inputs.
Auro D412/D415 Features Here is a look at some the features of the Auro powered loudspeakers: • 400 watt, two-way active loudspeakers for live sound applications • 320W LF + 80W HF power amplifiers (peak) • Ultra-wide, flat frequency response • Custom-designed, heavy-duty, 12”/15” long throw low frequency drivers provide enhanced bass response • 1.
Quick Start The following steps will help you set up your Auro D412/D415 loudspeakers. Setup 1. Turn the Level control on the rear panel fully counterclockwise. 2. Set the Bass and Treble EQ controls to the 12 o’clock position. 3. Turn the Power switch OFF. Connections 1. Connect either a line-level signal from your mixer (or other source) or a microphone to the Input jack on the Auro D412/D415 rear panel. 2. Connect the supplied power cable to the IEC socket on the back of the loudspeaker.
Rear Panel Layout 1. XLR Input Connector This female XLR connector accepts either a balanced microphone or line level signal. 2. 1/4” Input Connector Use this 1/4” input for connecting balanced microphone or balanced and unbalanced line level inputs. 3. Line Output Male XLR connector used to link multiple Auro cabinets. 4. Level Control This control adjusts the overall signal level at the input of the power amplifiers.
Connecting a Microphone Using a Microphone • Be sure that the Auro D412/D415 Power switch is set to the off position. • Turn the LEVEL control fully counterclockwise to the off position. • Connect the power cable to an AC socket. • Using a standard XLR cable, plug a microphone into the Auro’s XLR INPUT. • Switch the Power switch to the ON position. • While speaking or singing into the microphone, slowly raise the LEVEL control until you have reached the desired level.
Connecting a Stereo Signal Source Using a Stereo Line Level Signal • Be sure that the Auro D412/D415 Power switch is set to the off position. • Turn the LEVEL control fully counterclockwise to the off position. • Connect the power cable to an AC socket. • Using standard XLR or 1/4” cables, connect the line level signals from a mixer or keyboard into the Auro Inputs. • Switch the Power switch to the ON position.
Linking Two Speakers Per Side Linking two Auro cabinets per side: • Turn the LEVEL control fully counterclockwise to the off position. • Connect the left and right line-level outputs from a mixer to the inputs of two Auro loudspeakers. • Feed the Line Outputs to another pair of Auro loudspeaker inputs. • Now, run an audio signal from your mixer (like music from a CD) while slowly raising the Auro’s Level control until you have reached the desired level.
Positioning the Auro D412/D415 Speaker Placement Whenever possible, it is a good idea to raise the speakers above the heads of the listening audience. The Auro enclosures feature standard 1 3/8” pole mount receptacles with locking bolts, which are compatible with speaker stands from a variety of manufacturers.
Connections The Auro D412/D415 features balanced inputs and outputs, so connecting balanced and unbalanced signals is acceptable. Whenever possible, use balanced connections to other equipment to suppress interference.
