Dante audio-over-IP technology has been widely adopted in live sound, broadcast and studio environments. As Dante networks become bigger and start integrating many different types of applications including live sound, broadcast, intercom, P.A., recording and so on, it can be a challenge to match clocking and sample rates.

This challenge can be solved with the new Penta 721s – DNT from NTP Technology, which provides two separate Dante interfaces. The built-in sample rate converter makes it possible to interconnect two Dante networks with different clock sources and/or sample rates. However, the Penta 721s – DNT offers much more than that.

The Penta 721s – DNT is based on the Penta 721s base unit. As standard, the Penta 721s features a 64-channel Dante interface, one coax MADI I/O and eight AES I/O. Further, two MADI I/O, optical or coax, can be added as options. All of these are synchronized to the same clock.

The Penta 721s includes a slot where an optional I/O card can be installed. This can be a 128-channel Dante card, a dual MADI I/O card, an eight-channel AES I/O card, a dual SDI embedder/ de-embedder card, an eight-channel analog input card or an eight-channel analog output card. This makes the Penta 721s suitable for a wide range of applications, including conversion between multiple formats.

In the case of the Penta 721s – DNT, the option slot is configured with the 128-channel Dante card, which provides 128 Dante channels at 48 kHz, 64 channels at 96 kHz or 32 channels at 192 kHz. Apart from the high channel count, it also boasts a low-latency sample rate converter, which is used to adapt the clocking and/or sample rate of the Dante interface to the clock and/or sample rate of the Penta 721s base unit.

There is a routing matrix between the main and the option sections that allows the user to patch any input channel to any output channel, and even to multiple outputs simultaneously. The routing matrix includes a 256 x 32 summing engine. This combination allows the user to take, for example, a 96 kHz Dante channel on the option card, samplerate convert it to 48 kHz, and output it on the Dante and MADI interfaces of the base unit, and vice versa.


LIVE SOUND: A common issue in live sound is that some desks use 48 kHz sample rate, while others use 96 kHz; the Penta 721s – DNT provides an easy way of interconnecting these. The option section is connected to the 96 kHz desk with up to 64 channels, while the 48 kHz desk is then connected to the main section, either via Dante or MADI, with up to 64 channels. The routing between the main and secondary section is then set up, and even allows the channel sequence to be reordered. Because of the sample rate converter in the Penta 721s – DNT, the two sides do not even need to be synchronized.


RECORDING STUDIO: Recording studios can also benefit from the Penta 721s – DNT. Many recording studios use Dantebased personal monitoring systems. Some personal monitoring systems only operate at 48 kHz, for example, making it difficult—if not impossible— to record at other sample rates. And even if the personal monitoring system supports other sample rates, it can be cumbersome to change the sample rate of all Dante devices.

Inserting the Penta 721s – DNT between the recording converter and the personal monitor system provides a separation between the recording sample rate and the sample rate of the personal monitoring system. This allows the recording to be changed at any time without having to worry about the sample rate of the personal monitor system. In short, it provides a quick and efficient way of interconnecting Dante networks with different clocking and/or sample rates.

Hong Kong: A License to Thrill, Part 1 – From Hong Kong with Love.

Every Day an Audio Show

“Hey Richard, will you be attending the California Audio Show in California this summer?”

“Sure. Are you going?” I reply.

“Yes. I have saved up for the air and hotel and am excited to hear all those brands I read about in the press. The hotel is booked and the kids will fly  with their mom down to Disneyland.”

Does any of this sound familiar?

Similar conversations take place every year with folks planning their annual or bi-annual visit to the “event” known as the audio show.

Imagine what it would be like if every day there was an audio show? I wonder if you can. You may say I’m a dreamer, but I’m not the only one. A land where every day is an audio show? Well friends, that land is Hong Kong.

As a young lad, Asia always seemed to me to be an exotic mistress with its flashing lights, martial arts, mysterious foods, and beautiful women who were sultry by day and deadly ninja assassins by night. Asia was James Bond’s playground where baccarat trumped poker as the game of choice, played in broodingly lit red-tinged hotels where it seemed that You Only Live Twice.

Moving from British Columbia, Canada, to Hong Kong back in 2011, I planned to fulfill a two-year teaching contract and return home. Two years have now become nine and Hong Kong has become my home away from home. You Only Live Twice isn’t just a Bond film; it is the way I feel about my second life in Hong Kong (HK). HK has become a kind of mistress. She offers a totally different world from my western upbringing.

The endless array of premium sports cars weaving in and out of traffic, the well-tailored suits, and the fashionable thirty-somethings showing off their posh handbags, jewels, and exotic manicured pets. The world of James Bond that I imagined has come alive.

Zigzagging through the crowds of Hong Kong you shall assuredly improve your skiing skills as you navigate through the sea of people. Looking down from a drone’s eye view you will see a sea of people looking deeply into the glow of their smartphone screens all seeming akin to human bumper cars.

Had 007 been an audiophile, Hong Kong would have stirred his spirit and shaken his soul.

Hong Kong has likely forever ruined the excitement of the audio show-going experience for me in the west. Let’s see, what shall I do this fine Saturday? I know, I will get on the MTR and within 25 minutes I will be in Kowloon. A short walk from the train exit passing the sights and sounds of the crowds, I will arrive at the Grancastle Building in the MongKok district. A twenty-something floored building where virtually every floor is one audio showroom stacked upon another. Take the elevator to the top and head down floor by floor and room by room. Here, retail spaces are filled with some of the most expensive and exotic brands in the audio world. Oh James!

YG Acoustics, Luxman, Pass Labs,etc.

Twenty rooms? That doesn’t seem like a large show to me? Wait! I forgot to mention that within a five-minute walking radius of this building, there are six or seven more buildings that are beckoning you to listen and to open your wallet. Moreover, there are several other buildings specializing in second-hand items. Oh yes, the second-hand market where you will find your classic McIntosh or Kondo tube amplifiers or large Krell monoblocks or Magico and Wilson Audio speakers.

Ten to fifteen minutes in either direction on the train will land you in two other audiophile hotspots where you will once again find buildings with specialty audio retailers, repair shops, and of course stores dedicated to selling tubes. They will sell you rare NOS tubes, run of the mill tubes and — being China —fake NOS tubes. They will rub off the silk screening on new $10 tubes and put a fake label of an old NOS tube and charge $200. Caveat emptor.

Zubin Mehta and the Los Angeles Philharmonic: Complete Decca Recordings

Zubin Mehta and the Los Angeles Philharmonic: Complete Decca Recordings

In March, 1978, a friend took me to the campus of UCLA. He pointed to Royce Hall, where the LA Philharmonic made its recordings. Eager to look inside, I hustled across the quadrangle and walked through the door. In the entrance foyer I saw a snare drum, and facing it a music stand, a microphone, and a television monitor. Cables snaked across the floor. The music on the stand I recognized: Mahler’s Symphony No. 3. Stepping gingerly, I pushed open the door to the main hall. An enlarged stage was covered with risers, chairs and music stands, but no one ...

60 Seconds with Robert Trebus of d&b audiotechnik

Robert Trebus, d&b audiotechnik
Robert Trebus

What is your new position, and what does it entail?

My new position is director of Certified Pre-Owned (CPO) and Remanufacturing at d&b audiotechnik. The position entails operationalizing, communicating and drawing awareness to d&b’s new CPO initiative. As part of the program, customers are given the chance to purchase pre-owned, remanufactured d&b systems. CPO systems come with new energy-saving amplification and electronics, accessories, service, finance options and the same support advantages as when purchasing a new system. This new program is a small but powerful way of delivering premium audio while helping to reduce consumption of raw materials.

How has your background prepared you for your new role?

I have over 30 years of experience in senior management roles in the AV industry. Since the beginning of my career, I have accompanied and designed the commercial market launch of new media technologies and products. This wealth of experience was extremely valuable when developing this new sustainable business model for d&b.

What new marketing initiatives are we likely to see from the company?

As with every product that is manufactured by d&b, all CPO products go through a rigorous quality-control process including a through exterior, mechanical and acoustic check. The exterior check includes a full system inspection to confirm there is no damage, then all foam and seals are replaced and the exterior is repainted with the original d&b top coat. In the mechanical inspection, we check pins, rigging, links, wheels, latches, frames and chains for any damage, with everything tested and replaced where necessary. Finally, the CPO program product goes through the same rigorous frequency and impedance checks as new systems, and is subject to a listening test for performance qualities. CPO systems also come with a two-year warranty, and a five-year factory warranty to all new parts.

What are your short- and long-term goals?

Our short-term goal is to make our partners and customers aware of our CPO initiative and its benefits. Not only can these systems significantly reduce our carbon footprint and the consumption of raw materials, but they can also save customers money and extend the product’s life even further.

Our long-term goal is, of course, to make a lasting, positive impact on our environment. At d&b, we’re really conscious of the impact that the entertainment industry in particular has on the environment. Our customers, partners and artists alike recognize just how important is it that we protect the planet and operate in a sustainable way. Everyone has a part to play in “greening” the entertainment industry, and while the industry as a whole has a long way to go to be more sustainable, it is reassuring to see leaders in the entertainment industry beginning to voice their concerns.

What is the greatest challenge you face?

When you look at the overall ecological impact of our industry, it is easy to be overwhelmed by the huge task that lies ahead. We cannot let the enormity of the challenge deter us. While the challenge can seem difficult, it is important that we continue to find ways and take the necessary steps to reduce our carbon footprint. We still have a long way to go to ensure that touring and festivals are more environmentally friendly, but we should remember that small steps can have a big impact.

There is a misconception from the organizational and the customer side that sustainability means expense, but our studies concluded that remanufacturing not only significantly reduces ecological footprint, but it also makes products economically very attractive!

Sennheiser Launches MD 435 and MD 445 Vocal Microphones

Sennheiser MD 435 Vocal Mic
Sennheiser MD 445 and MD 435 Vocal Mics.

Wedemark, Germany (November 17, 2020)—Sennheiser has introduced two new vocal microphones—the MD 435 large-diaphragm microphone, bringing the company’s dynamic MD 9235 capsule to a wired vocal microphone for the first time; and the MD 445, an LDC with a tight super-cardioid pick pattern.

The MD 435’s lightweight aluminum-copper voice coil is intended to provide fast transient response, according to Sennheiser, in an effort to provide detailed, transparent sound. The large-diaphragm microphone features dynamics of 146 dB(A) and can handle sound pressure levels of up to 163 dB/1 kHz.

How to Pick the Right Mic to Record a Vocalist

Meanwhile, the MD 445 is designed for use in a large, loud, live sound atmosphere. With a high-rejection, super-cardioid pick-up pattern, it reportedly offers uses considerable gain before feedback. Dynamics are wide at 146 dB(A) and the microphone is said to be able to handle sound pressure levels of up to 163 dB/1 kHz. It also features a metal casing and has a shock-mounted capsule, while a hum-compensating coil protects the microphone against electromagnetic interference.

For use with Sennheiser’s wireless transmitters, the capsule of the MD 435 is also available as the MM 435 microphone head, and will soon replace the existing MD 9235 capsule. Likewise, the capsule of the MD 445 is also available as the MM 445 microphone head. Both capsules can be used with Sennheiser wireless series ranging from the evolution wireless G4 and 2000 series to Digital 6000 and Digital 9000.

The MD 435 microphone and MM 435 microphone head retail at EUR 499 (roughly $591 US) each, while the MD 445 microphone and MM 445 microphone head retail at USD $619 each.
