Mod Monitor Question

I've had REALLY good luck with J-Squared. TFT at times can be quite clueless. I try to just call or send stuff to Jim and avoid them all together if possible.

What are people's thoughts, opinions and comments on the QEI 691 mod monitor?

I had one I used and while it was quite good, they're not cheap to repair if sent back to QEI. The factory charges about $1k flat rate repair to rehab any 691, so if you send one it you might as well blow it up before you send it in. I wasn't thrilled with how compact they have some of the boards mounted but other than that it did the job well.

I personally still like the Belars, especially in a studio - while analog meters may be dated in some views I like the visual presence they give to the staff.

I always put the 844 or the QEI in the studio where the program folks could look at the Other Guys, and the Belars at the transmitter where I could feed them a cavity sample and see just what the hell was going on in the transmitter.

Anybody have opinions on Innovonics Mod Monitors? Price seems great for features. How are they for reliability, accuracy, etc..

I have one. Several people bought them for the $1200 price. Great if you want to dink with the greenie screwdriver and set up the station. Not very selective for a frequency agile tuner.

As weight is concerned it is much easier than carting around a set of any other mod monitor. Seems as accurate as any other.
 
I agree on the Inovonics monitor...few quirks such as station selection, as you mentioned, but this is not something that you change often. Small, accurate, and all in one box...price outstanding, and most importantly, dependable. JBI

I take it you are referring to the older (530) unit. It appears the 531 has a number of preset buttons.

J Squared can just about fix ANYTHING ever made for broadcast and do it better and cheaper than the company who built it..I had a STL rcvr that started noising up on me...sent it to Jim, got it back a week later, totally recapped, realigned and it heard BETTER than it did originally....also freq response was cleaner..DEFINITELY get an AAA+++ in my book (to borrow from Ebay feedback :)

Do they have a website and how helpful are they if you just want a little info on something?
 
Jim does not have a web site, mostly because he has never needed it. His small company is too busy as it is. I visited him in April of 2006, as I was going to Portland from the Bay area, wanted to drop off a couple of items to repair, and his shop is right off of the highway. Here is the contact info:

Tell I sent you.
 
Oh, by the way, I have two of the QEI monitors that I just removed from service. They need calibration pretty badly, but they do work. I talked to Jim about a rebuild/upgrade and he will do everything for $900 each. This includes replacing the troublesome calibration pots and higher temperature caps. Jim says that after the rebuild/upgrade they should be good for ten years. I would be happy to see them go to a good home, as HPR has replaced everything including these monitors, and storage space is getting a bit tight.

Let me know if you have any interest. They are currently in my shop in Honolulu.
 
The only issue about the QEI is you don't want to align (or confirm) a stereo generator with one. The most I could get out of a recently calibrated QEI was about 50 dB when a Belar FMS-2 measured greater than 60 dB on the same stereo generator.

The peak weighting option on the QEI, VDPO, does work fine so as a general monitor it is not bad. Unlike the TFT or Belar, there is no way to change the weighting from the outside of the QEI. I have the QEI, TFT & Belar and prefer the TFT for off air measurements of peak-weighted total modulation. YMMV.
