A client asked for a way to balance a guitar pedal so he could send and return Line Level to his guitar pedals.   He wanted a way to use his pedal collection as effect sends.  We came up with a modified Ward-Beck Systems POD-1.  The POD-1 offered op-amp gain adjustment trimmer pots so you are adjusting the gain of the balancing amplifiers.

The un-balanced output impedance is roughly 30Ω and the unbalanced Input Impedance is 47kΩ.  It’s a pretty safe assumption that mopst guitar effects can operate within these ranges.

You could also use this as a re-amp tool and a hyper-transparant Direct Inject box for keyboards and anything unbalanced.


XLR input Balanced +4dBu differential Receiver to an RCA connector to a 1/4″ TS jack that feeds the pedal then return to the opposite.


If you are interested in trying one out contact Ward-Beck Systems IMG_0477-2015-03-04

I was at a Hi Fi shop in Ottawa and they would not demonstrate the RX202 for my brother… Of all the things in the store, this was not for sale for some reason…

here is a video of what it does

Was working on my Micro controller reading and had a need for a calculator to check my work for Successive Approximation of Analog to Digital signals.

WIKIPEDIA:  A successive approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation via a binary search through all possible quantization levels before finally converging upon a digital output for each conversion.

A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”

Sounded like the kind of math challenge I like:

The answer is 452.893Hz

To test and confirm that it’s calculating properly, this is up 100 cents making G# 440

This is down 100 cents making A# 440

Learning about harmonics, this handy calculator helped with understanding the math.  I love excel!

you know it’s going to be rough if you’re on page 894 of a textbook called “Technical Mathematics with Calculus”2015-01-26 23.51.20

I was lucky enough to get to visit the new Atmos mix room at Deluxe Toronto.  This was the deadest big room I’ve ever been in.  It was impressive to hear the system.  Being a part of the AES gave me an incredible experience of A/B-ing the new IMAX mix room at Technicolor and the Atmos room at Deluxe.   In my opinion the ideas of IMAX immersive technologies translate much better.   The guys at IMAX got it right.

They had a guy from dolby explaining a little about how Atmos renders… very interesting how it translates from room to room.

Dave Adams did my a solid today.  I needed some support cut to exactly 1.6 *12 plus 0.02 worth of “wiggle room” spaced over 12 modules.  He has the tools and knows them too well!  Thanks again Dave! 2015-01-12 23.06.44 2015-01-12 23.07.25
