Frequently Asked Questions - D415 SAMSON

How do I connect a microphone to the D415 speaker?

Set the switch to Off, turn the Level knob to minimum. Connect the microphone via XLR to the Input. Turn on the speaker, then gradually increase the Level. Use the MIC zone of the Level knob.

How do I daisy-chain multiple Auro speakers?

Use the Line Output (XLR) of the first speaker to connect to the input of the next. This allows you to chain multiple Auro speakers.

What does the red Peak indicator mean?

The Peak indicator lights up when the amplifier reaches its limit. If it lights frequently, lower the Level or reduce the source signal to avoid distortion.

How do I adjust the equalizer?

Use the Bass and Treble controls: Bass adjusts lows at 80 Hz, Treble adjusts highs at 12 kHz. Each provides a ±15 dB range. Start from the center positions.

What type of cable should I use for an unbalanced line signal?

You can use an unbalanced 1/4" jack cable on the Jack input. For a balanced signal, use an XLR cable.

How do I use the speaker as a stage monitor?

Place the speaker on its side: tweeter to the left gives a 30° angle, to the right gives a 48° angle. This directs sound towards the performer.

What is the maximum power consumption?

The maximum power consumption is 456 W. Use a power outlet suitable for your region's voltage.

How do I clean the speaker?

Clean the device only with a damp cloth. Do not use abrasive products or solvents.

What to do in case of malfunction?

Consult a qualified repair service. Do not open the unit: it contains no user-serviceable parts. Contact Samson to get a return authorization number.

Can I mount the speaker on a stand?

Yes, the speaker is equipped with a standard 35 mm pole mount socket. Use a stand capable of supporting the speaker's weight (22.2 kg).

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 1/4'' phone jacks that handle microphone or line level inputs. The XLR Line Output allows you to "daisy-chain" multiple Auro cabinets together to create larger sound reinforcement systems.

For added speaker protection, the Auro D412 and D415 feature dual optical limiters that keep your speaker sounding perfect at any level, and the integrated two-band equalizer allows you to sculpt the mix to your desired sound. Each cabinet's trapezoidal shape allows it to be configured for either front-of-house use, or for operation as a wedge-style monitor. In addition, the compact cabinets can easily be stacked, using the built-in bumpers or can be stand-mounted using the integral 1 3/8" polemount receptacles.

Each Auro PA system's durable enclosure is made of high-impact polypropylene with a scuff-resistant textured finish, and include a heavy-grade steel grill, offering excellent protection against wear and tear for truly portable audio. The Auro active monitors are ideal for live music, DJ, lecture, and installed sound applications, or anywhere serious power and superior sound quality are desired.

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. In a smaller setting like a school cafeteria, library, or a mall kiosk, you can also use the Auro loudspeaker in one of the tilt back monitor positions, which will improve the projection of the speakers and may eliminate the need for speaker stands.

Note: When using a speaker pole mount, be sure the pole is capable of supporting the weight of the Auro loudspeaker.

Note: Always have another person to assist when mounting the Auro speaker onto a speaker stand, or when adjusting the stand while the speaker is mounted on the stand.

Using the Auro D412/D415 as a Floor Monitor

The Auro D412/D415 is an ideal solution for stage monitoring and thanks to its unique design, two wedge monitor positions are possible. When placed on its side, with the high frequency horn facing to the left of the enclosure, the Auro is tilted at a 30 degree angle, optimizing performance when used on a large stage. When placed on its side with the high frequency horn facing to the right of the enclosure, the Auro is tilted at a 45 degree angle optimizing performance when used on smaller stages.

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.
