It's reported that Mike Pinder of the Moody Blues passed away today.

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!

Great review. I'm a part-time operator, and have (4) DZR10's along with (4) DXS15-xlf subs. Great combo, and I don't think can be beat for the price, weight, cost, quality, and design. I previously had an SRX  rig (12"/18") and sold it in favor of the Yammies.

I also have (4) db technology ig4t's - which match well with the Yamaha subs, though if using all 4 ig4t's (stacked) they will definitely outrun the subs. I'd like to pick up a 3rd pair of subs for more SPL and to do 2:1 cardioid.

I haven't needed to yet - but if I used the ig4t's stacked (2/side) on a bigger outdoor gig, I think I'd lean towards renting some bigger subs either way. Danley TH118 (2 per side), or some high-power 2x18's (2 per side) - RCF 8006 etc.

also there is a setting called audio filter, I think, that will help large arena dropout.

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.

You could run it in daisy chain mode and have one cable for each, though either port would still work for both dante and/or control, there is no way to isolate the different networks to specific physical ports.

Darn.
So, the manual says "For a technical reference of the Ethernet Port, please refer to section 7.3. Additional information is available in the Lake Network Configuration Guide."

I have not been able to find this elusive "Network Configuration Guide". Anyone have a link?



N/M - I found it in the controller's Documentation folder. I concur that separating the networks isn't that easy. I could maybe leave it in redundant and use the primary for control (without connecting to the Dante network) and the secondary for Dante... I've never tested the theory though if a single device can be on secondary while the rest of the network is primary or it's all-or-nothing...

[size=78%]Does anyone know if it's possible to make one RJ45 on the Lake LM44 for Dante and other for control? I'd prefer to not have them on the same cable for simplicity.[/size]

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.

With the nomination deadline the day after tomorrow (Friday April 26 5pmEDT), this'll be the final post from me in this thread.

Thanks to those who have nominated me, and I'm happy to have had a role in causing more people to upgrade their membership to full Member.

By my inexact count, I'm about 14 nominations from reaching 100. Nobody has ever been able to achieve success, although a number have tried, and it's both encouraging and disappointing to get so close to the binary decision. And to be the first and only...

If there is still anyone who is a full Member and would be interested to cast a nomination, it's easy and I'd appreciate it:

Create an email to [email protected]

Subject line: 2024 Election Nomination-Mortensen-President

Content: I nominate Dan Mortensen for AES President in the next election.

Then add your name and membership number.

It's probably too late to complete the Associate->Member upgrade in time to nominate, but if you have been considering upgrading, go ahead since there's no deadline for that.

A clear benefit from being a full Member is that, if you've paid dues for 20+ years, and been a full Member for 5 years when you turn 65, you can apply to be a Life Member and not have to pay dues again. You get in free to Conventions but not Conferences. That's a good deal and a benefit I enjoy.

FYI, a lot of the meetings I've done for my Section have been about the subjects covered in this forum at one time or another, and I've always enjoyed and learned from being part of this group.

Here is a document that's now on my AES profile; if you scroll through it past the bio stuff there's a list of the meetings and links to the meeting summaries. A lot of them are us getting piles of gear together and messing around with it, as we like to do.

Thanks to those who have helped me get this far, and especially to Dave Stevens for creating this wonderful resource that we still enjoy every day.

We got to play with the Bluetooth feature, and it's pretty cool. Won't work with the Apple airpods, but we did get it working with a pair of Beats earbuds and also a one of those Bluetooth speakers.  Pretty cool, no kidding.  You could use a Bluetooth speaker as a squawk box instead of needing a separate wired box.
