Audio professionals looking for an active speaker that can handle any situation with confidence should check out the HK Audio LINEAR 3 115 FA, a powered speaker that is suitable for a wide range of applications, offering top performance and easy handling.

The speaker utilizes a 1200W Class-D amplifier to drive the 15" woofer and 1" high-frequency driver, which combine to offer a full-range frequency response (58 Hz to 16 kHz) with plenty of volume to cover an audience (135 dB SPL). Notable features include advanced DSP with a multiband limiter and four EQ presets to help dial in your best sound. A DuoTilt 3/7° pole mount flange adds flexibility when deploying. A power cord is included.

• Thanks to its DSP filtering that is fine-tuned to listening habits, the LINEAR 3 active speaker system has you covered in a wide range of different performance conditions.
• The system is easy to operate from the stage, meaning you can quickly get to grips with the acoustic conditions.
• With filter presets, intelligent multiband limiting, and FIR separation, you’ve got all the best prerequisites for getting the most out of your sound.
• Stylish slotted grille design

• The advanced DSP technology driving LINEAR 3 has one main purpose: to make the job of musicians and DJs easier. LINEAR 3 gives you the ultimate sound in any situation and it’s simple to use.
• An intelligent multiband limiter and filtering of the frequency response in the ‘Contour’ setting ensure a consistently sweet and assertive sound, from super quiet to really loud.
• The multiband limiter monitors and controls the relevant frequency bands separately, only intervening when it is needed.
• As a result, LINEAR 3 guarantees an impressively effective sound experience, even for semi-professional musicians and DJs who are not dedicated PA specialists. This gives musicians on stage more room for musical creativity and a top performance.

Bass Boost/Flat (LF) switch

• This DSP-driven EQ optimizes the frequency response for the given application.
• Setting this switch to "Bass Boost" pumps up the bass. This boosts a broad band of bass frequencies in the range between 60 and 100 Hz and extends the low-end response.
• To use the speaker as a top unit combined with a subwoofer, set this switch to "Flat (LF)“. This ensures the frequency response remains linear all the way down to the cutoff frequency for optimum subwoofer coupling and a homogenous overall sound.

Flat (HMF)/Contour switch

• This DSP-driven EQ optimizes the frequency response for the given application.
• Setting this switch to "Flat (HMF)“ conjures the optimum linear frequency response for live performances and for operation in combination with subwoofers.
• Setting this switch to "Contour“ dampens a broad band of midrange frequencies centered at 3.5 kHz by as much as -6 dB. This takes the edge off the sonic image to prevent and mitigate early listening fatigue, particularly at short distances where audience members are close to the speaker. The overall volume is not affected.

The built-in HK Audio MultiGrips make handling the speakers a breeze and ensure even more safety in every situation. They also allow for professional flying hardware to be fitted. The TB-45N or TB-45NQ tilt brackets can be mounted directly to the MultiGrips on the LINEAR 3 115 FA, making them ideal for professional rigging or installation. The LINEAR 3 series have 4 x M8 mounting points and can be flown by mounting AP-8 attachment points.

The DuoTilt stand mount helps to align the speaker towards the audience reliably so that it provides the best sound. The preset 3 and 7° tilt of the stand mount means you can choose the right alignment, regardless of the setup.

Q: 2. Who makes this lens?

A: The Pentax HD PENTAX-D FA 15-30mm f/2.8 ED SDM WR Lens is manufactured by Pentax.

Q: 3. What's the difference with the Tamron SP 15-30mm f/2.8 Di USD Lens?

A: Tamron does not have Pentax mount

Q: 4. With a 15" woofer and 1" tweeter, where does that leave the mid-range frequencies? Is there a gap in between?

A: Two-way speakers do not leave a gap in frequency response. The two drivers are separated by a crossover, which divides the frequency spectrum (within the limits of the speaker's frequency response range) with two filter curves to create a seamless transition between both drivers. Two-way speakers are by far the most common design for studio monitors, portable point-source speakers like the iHome iHPA-1500-LT, etc. There is generally no need for a dedicated mid-range driver.

Q: 5. So how does the D10 with say maybe an AKG 414 or two in whatever the highest quality possible compare to the D100 in DSD mode using the onboard mics? Also, can the D100 use the XLR-1 Mic Adaptor that works with the PCM-D50?

A: The AKG 414's will trump the onboard mics of either machine.

Q: 6. Is this an internal focusing lens?

A: It is. And pretty much spot - on. It is my day to day workhorse for Real Estate Photography.

Q: 7. Is this lens ideal for astrophotography?

A: It is a nice one for it. It depends on what you are trying to capture. I used it this summer to catch a small portion of the tree line along with the sky. I also used the D FA*70-200 to capture a different perspective. I use this lens primarily for architecture and real estate. It will do nicely if your main need is for astrophotography.. The real key to star and sky shots is the astro tracer function in the k3 and k1, though (I shoot with the k1). You will absolutely love this lens.

Q: 8. what is the diameter of this lens hood? i am shopping for a camera bag that could fit this lens and hood.

A: Nikon HK-42 Lens Hood is 7 inche wide, including the tension knob.

Q: 9. Can I record audio from internal mics and external simultaneously?

A: This recording scheme is not possible as the inputs are configured automatically when external microphones are connected.

Q: 10. Would you recommend this lens for portraits?

A: For portraits, a longer lens such as 85mm or more is recommended. A 15-30mm would be too distorted for portraiture. This 85mm would be a better option: https://bhpho.to/3dldCD4
