I'm not sure on how the equipment purchase times is doing now, but most places are still taking long periods of time to get equipment out to customers. Reach out to a rep and see what they say.

More data!!!

Ok, so initially we will rent PA's to spec for the venues. The Purchase is for the actual tour next year. This company is looking to become a full production company, so that is the reason for purchase, it will have its own market. There is a Tour Manager already in place and I believe I have my Monitor Engineer in place as well. I just received the contract the other day, and signing is early in May, rehearsals start first of June.

I am on the lookout for a Systems Engineer. I would prefer one that will play as an A2 as well. The early dates are going to be small enough that having a dedicated role would not hold value. I know I can sell the management on paying a retainer salary for someone who can do both as needed. I am semi responsible for finding the Audio Talent. I.E. I am not required to, but am being asked to build my team. I have one A3, and about 95% sure on my Monitor guy. So, if anyone knows a Systems Engineer that is ok with playing as an A2, please let me know, I would love to talk to them.

I have an NDA, so I can't divulge much else, but I can say that while initially things seemed weird, everything I was told has turned out true, and things are panning out as you would expect with the exception of being time crunched. 3 months of rehearsals seems tight to me, I would prefer 6+ months, especially since the mixer option has not yet been decided. My brief conversation with my Monitor Engineer suggests we are looking to the Rivage PM5.

Thank you all and keep em coming!!

In the stand alone FSII there is a similar setting.

Are you referring to the "Audio RF Filter" setting?  The manual says that it "may help with audio dropouts" but is otherwise vague about what it does.

Hey Team,

I'm looking for a continuously-variable sine tone generator for speaker test and QC applications. 

A sine sweep can be very revealing of buzzes, rattles, port noise, driver distortion, etc.  However, the software-based sine tone generators I've met (e.g. smaart) seem to be 'stepped,' both in amplitude and frequency.  That waveform discontinuity, and resulting blast of harmonics, can be very distracting, enough to compromise any real critical listening. Chirp tone playbacks are okay, but you can't 'dwell' on a zone of interest like you can with manual control.

So, I'd like to find a simple hardware device that can generate sine tones at an arbitrary frequency and amplitude, each with a dedicated knob, and a smooth sweeping behavior as the knobs are adjusted.  Kind of like the Meyer Sound SIM hardware sine tone generator. 

Ideally, it would have a line level XLR output, and be compact, and economical.  E.g. not a lab-grade arbitrary function generator with >mHz capabilities...

A bit of googling turned up this Tenma 72-490
https://www.newark.com/tenma/72-490/compact-audio-generator/dp/09P2110 
... which seems to meet my objectives except for XLR out. 

Does anyone have a better recommendation?  Anyone used this device and have real world experience to comment upon?  Thanks!

It is the nature of digitally generated tones to have steps between discrete frequencies. In theory these steps could be made quite small I don't know that coders have been willing to make that effort.

Back in the day I had good success with customers using the sine wave output from the LofTech TS-1 for speaker testing. The analog sine wave was continuously variable.

AFAIK that SKU is no longer in production.

And use the latest firmware in the packs and transceivers. Also, PEPP^® (Pete Erskine Pizza Pan) works; just put the transceivers as high up as possible. These tidbits are for the older E1 Freespeak II: The IP transceivers do not suffer nearly as much from multipath.

The PEPP^® I use is an actual circular Pizza grate to shield the top of the E1 transciever from high RF reflections.

HERE IS THE SETTING IN ECLIPSE FOR LESS DROPOUT.  In the stand alone FSII there is a similar setting.

Nature sounds.  See more here, courtesy of our friends at the PNW Chapter of the Audio Engineering Society and Dan Mortensen.  Dugan calls it "immersive" and having enjoyed hiking and camping for decades, I'm inclined to agree.

Dan is a man of many, deep talents and one helluva nice guy whom I have had the honor to meet on numerous occasions. During Covid when they couldn’t do their annual  trip to Yosemite to document the sounds he and his crew camped a couple of nights at our Sierra Foothills place (oak/pine woodland at ~3000 ft) and apparently got quite the trove of animal sounds. It exceeded my expectations and while I could not identify some sounds I’m sure Dan et al. figured it out.

If you don't want to spend a lot of money but want super high quality look for a transmission test set.

For $100 on flea bay you should be able to acquire a pristine specimen.

Agree. Get a used HP analog sine generator and make a nice adapter cable. HP got their start making a sine generator using a unique circuit with an incandescent lamp as the amplitude stabilization element.

An aside: I picked up one of the early (not the first) vacuum tube sine generators in pristine condition. Only the rotting leather handle betrays its age. The tubes are still the original HP branded ones. One nice thing about the old generators is that they have quite a bit of output, and it’s transformer isolated and balanced. You can drive a speaker to audible levels directly from the generator although for serious “sweeping out” you still want to use a power amp.

Hey Team,

Peter,

I just pulled up the default Generator utility in my AudioTools app and it has a "Fine" setting that might suit your needs.  It also has octave and 1/3 octave settings, which is the one that I typically use.  I realize that you asked specifically for hardware solutions, but I thought I'd mention this option since its inexpensive and very portable.  One nice feature of AudioTools is that you can install the app across all of your portable devices for the price of one license.

If you don't want to spend a lot of money but want super high quality look for a transmission test set.  Popular brands are HP, Halcyon, Hekimian, Ameritec  and TTI all popular brands.  The HP 3551A has a Vernier knob for level and frequency and is built like the proverbial brick shit house.  Halcyon (later made by CXR Telecom) 701A was one of the most popular field instruments with the Bell techs and is equally well built, same features. 


You have to add an XLR but that's not a big deal.  I just lop off a short jumper as this equipment has 5 way binding posts.  You can get an XLR to bananas if you a super anal. 


I have the HP 3551A on my bench and use it for servicing hifi and commercial gear.  It's a great piece of kit.
