DAD AX32: test in progress in my studio – part Two

Ok,

after first approach based on comparison listen (see DAD AX32: test in progress in my studio – part One), I verified frequency and phase response with Metric Halo SpectraFooCompleteX.

All settings are controlled by DADman software (see figures bottom) like matrix or Mic/line switch. When you change Mic gain or Line out level you can hear the relay click on.

All audio connections use DB25 with Tascam pin-out.

In front AX32 has four buttons to change sample frequency and clock master, a little screen to check settings and a double series of sixteen leds to visualize carrier (digital signal) and audio presence.

Here DAD AX32, it look very nice 🙂


After I installed Dante controller and  Dante virtual sound card both by Audinate and I created an audio network where my computer (with audio application) and DAD AX32 are two clients.

Dante virtual soundcard has to work necessarly without a Dante PCI card compatible. It uses ethernet in your computer gateway. With Dante controller you can manage a flush of 64×64 channels audio at 48kHz@24bit or 32×32 channels audio at 96kHz@24bit with 1Gbit of bandwidth. You find all specific here.

I created a multicast and I managed audio interchange to and from AX32 with virtual routing.

Well, I opened SpectraFoo and I changed soundcard with Dante (it appears on available audio cards) and I ran signal generator with pink noise to test AX32.

I used Transfer Function window to visualize the difference between original signal (reference) and it after AX32 AD/DA (response). In this window it’s possible to visualize Power vs Frequency and Power vs Phase.

I tested AX32 at 96kHz and 48kHz.

At 96kHz I checked a bandwidth very width (8Hz to 43kHz) with an excellent phase response.

Also at 48kHz I checked a bandwidth very width (8Hz to 22kHz) although with a slight drift phase response at high end.

Also I tested Ax32 with FuzzMeasure, an audio and acoustical measurement application, and it confirmed SpectraFoo audio bandwidth analisys.

Here all SpectraFoo graphics:

My conclusions on the DAD AX32 is that it’s the best converter I’ve ever heard. It’s very valuable into mix and fundamental into mastering because very wide bandwidth with clean mid frequency and extended low and high frequency are a necessarly conditions to work fine.

Have a nice day,

Lorenzo

DAD AX32: test in progress in my studio – part One

Hi,

today mr. Mauro Piatti, manager of Te.De.S., and Laura Lionti delivered in my studio the new DAD product: audio converter AX32.

This is a modular system which manage many options: eight to thirtytwo channel AD/DA/DD, AD Mic pre, DA gain control and sample rate from 44.1 to 384 kHz. Connections avalaible AES3, MADI coax/optical, ProTools interface and Dante (TM) protocol (ethernet IP).

Ax32 is controlled by a simply hardware interface (sample rate and sync) or by DADman software to manage internal I/O routing.

I chained AX32 with my Apogee Rosetta 800 by AES/EBU and we compared them in real time.

We listed (me, mr. Piatti and ms. Lionti) my live recording at Memo restaurant recorded at 96kHz@24bit and several master finalized in my studio.

We agreed that DAD AX32 has a superb and depth sound and in particulary a better mid-low frequency detail (very important for intelligibility) and a superior presence of the high frequency.

Tomorrow I’ll test further and get back to you.

Lorenzo

today at our studio: Alessio Lorenzi

Today Alessio Lorenzi has been in our studio to record and mix his new single: Ragazzo di Periferia.

He played his beautiful acoustic guitar Gibson Chet Atkins.

We mixed on my D&R Dayner consolle, oldest e warmth piece of gear. I like it!


Tracks sheet is (drums and bass were recorded in a previous session):

Bass Drum in & out – AKG c414 + AKG D112 into Focusrite ISA428

Snare Drum up & down Shure – SM57 + Sennheiser MD409 into Focusrite ISA428

Hi-Hat – AKG c451-e into Millenia HV-3R

Tom up & down – Shopes cmc6/MK4 + Sennheiser MD421 into Focusrite ISA428

Floor Tom up & down- Shopes cmc6/MK4 + Sennheiser MD421 into Focusrite ISA428

Cymbals L&R recorded down (microphone placed under cymbals at approximately 50cm) – Shoeps CMC6/MK4 into Millenia HV-3R

Over Head L&R with two Crown PCC160 upside down on the ceiling into Millenia HV-3R

Electric Bass – direct inject into Focusrite ISA220

Gibson Chet Atkins – direct inject into Focusrite ISA220

Yamaha digital piano CLP-170 – direct inject into TL Audio C5001

Vox – Shure SM58 into Focusrite ISA220 (YES!!! I have Neumann U87ai but today SM58 sounded very cool and I think it’s important the sound and not the brand, isn’t it?)


Mix had amazing sound, we were very satisfied.

Alessio Lorenzi here at the end of day.Alessio Lorenzi 19nov2013

Cheers,

Lorenzo

Andrea Fedeli: a fine musician and arranger

Today I mastered on some Andrea Fedeli’s songs.

Who is Andrea Fedeli? He is a customer and collaborator, piano player, leader of his jazz trio and an especially fine musician and arranger.

Starting from this year, we agreed on a contract to realise the mastering of all his songs.

As arranger he collaborates with the tv documentary “Overland” (aired on RAI TV) which talks about adventure travel through all continents.
Last July it released the album “Overland 14 – Caucaso” including some songs from that season. I mastered all songs.

Logic Pro strikes back

Hi,

another day with Logic Pro and his trouble…

I have still got problems opening logic project, despite I used AIF files…

To get it solved i changed all audiofiles names and I located them after opening the project….

At this point I had not more problems (I couldn’t believe) and I bounced (Logic worked very slow ) the project into stereo file.

Tomorrow I’ll generate (hope so) a different version of the master:

– Hi-End version (96kHz@24bit)

– Video version (48kHz@16bit)

– Cd version (44.1kHz@16bit)

– MP3 version (320kbits stereo)

Just authorized by my customer I’ll link one or more songs of this work.

…and the mix be with you  😉

Lorenzo
