Remote Balance Control: on Tube Integrated Amp?

comments from others


"I think channel balance control is an essential feature. It would be almost a miracle if a system is truly perfectly balanced absent a control (perfect electrical balance, perfectly symmetrical room, perfect speaker placement, etc). When I used a Levinson No. 32 preamp, a change in channel balance of .2 db was clearly audible even though an absolute volume change of a 1.0 db was not audible when playing music. It is SO much easier to hear a channel balance difference than a change in volume. A balance change is particularly audible when you can make immediate comparisons (remote control, another essential feature, to me)."

" Even really expensive cartridges have specifications suggesting that channel balance would be within 2 db. If two channels are off by that much, that is a VERY audible difference. I like the feature on some linestages that allow for an input by input change in channel balance so that each source can be custom tailored for balance. This would make life easy when switching between phono and other sources.".

" One way the balance control is needed with digital is with the many CDs (and streams, and downloads) of vintage material in which (for whatever reason) the balance was either off to begin with or has shifted due to deterioration of source tapes. I have many stereo CDs from the sixties in which the vocalist is just enough right or left of center to be disconcerting. The balance knob comes in handy.".

btw, 

One of the features I love about McIntosh preamps is the Mode Dial, stereo/stereo reverse/mono/l to r/r to l/l+r to l/l+r to r. ...

I use this to get my speakers matched. They have presence and brilliance controls, and need to be carefully and properly adjusted. Cassandra Wilson; Richard Burton; No More Tears Duet with Barbra Streisand and Donna Summers help. I find test records are best for TT refinement of Anti-Skating l/r balance.

Above done, if the balance is off a speck, it's the source, and a small tweak can be a magic improvement, not just a 'fix'.

Just sharing stuff I find until I find a tube integrated with remote balance

this is using the Chase unit for remote volume of a subwoofer (not balance or tone). Probably before home theater had better individual channel controls, but still might be useful, direct adjustments/vol/on/off without any menu diving.

From the posts I’m seeing on the New BFD Poll thread, it looks like a lot of people are interested in remote control for their subs. Rather than sidetrack that thread, I thought I’d open a new one here on the topic.

The cheap and easy solution: A gizmo called the Chase Technologies RLC-1. It connects between the receiver and the subwoofer. Sure, most receivers these days can control sub levels through the remote, but you usually have to shift through a lot of on-screen menus to do it. The RLC-1 makes sub levels readily accessible - like the main volume control - which to me is the way it should be.

A brief background on the RLC-1: Back in the mid 90s a maverick company called Chase Technologies came out with the RLC-1 (for remote line controller). It was designed to upgrade older two-channel receivers for remote control capability, accomplished by connecting across the tape monitor loop. All of your components would plug into the RLC-1, which would then allow input selections and basic functions like volume, balance, bass and treble to be remote controlled. The RLC-1 was tested in Stereo Review and got good marks for its excellent specs and sonics. List price was $150, but Best Buy sold them for $100.

Chase Technologies is long out of business, but occasionally a RLC-1 will show up on eBay (search “chase rlc-1” or “chase technologies” from the home-page search engine). When you find them, they will typically sell under $50.

Eleven years later I’m still using my RLC-1, and it works very well for this application. It does have a few minor problems, but they have easy solutions.

• The first is that the front-panel LED’s are ridiculously bright. I fixed this by taping a piece of 20% window tint over them.
  
• Second, the RLC-1 only has a visual reference for volume level changes, a row of blinking LED’s, and it’s rather vague and ambiguous. Once you move the volume setting up or down it’s pretty much all up to your ears. If you want to then move it back to the point where you started, it’s hard to do that with any certainty.
  However, there’s an easy fix for this, too: When the RLC-1 looses power, it re-sets itself to default settings. So what I did was calibrate my reference sub level to the default, and then plugged the RLC-1 into a switched outlet. This way anytime I change the sub level, it goes back to the default/reference setting the next time I power up the system.
  
• Third, the RLC-1’s default output is lower than the incoming signal, so you’ll have to compensate by increasing the signal from the receiver’s sub output or at the subwoofer itself.

If you have a remote that runs macros, you can simply include the RLC-1 in the turn-on sequence, assuming your remote can be “taught” commands from other remotes. The default input is “VCR,” so that’s the one you want to use – otherwise you have to change the input every time you turn the system on.

It’s interesting how times have changed. When I first started on the home theater forums back in ’99, I mentioned remote controlled subs in general and the Chase specifically a few times, and generated near zero interest. Maybe it’s an idea whose time has come. I for one think the concept is very cool. I wouldn’t dream of having a system without it. It's also a quick and easy way to turn of the subs for late night viewing when others in the house are sleeping.

Another viable option is an old stereo pre amp with remote control. I looked through my old Audio Equiment Directories from the mid-to-late 90s and came up with a few that listed for under $1000. If you can find them on eBay or some other auction site, they should be selling pretty cheap by now, although they’ll probably be higher than the Chase:

• Onkyo P-301
• Adcom GFP-710
• NAD 116
• Technics SU-C1000
• Yamaha CX-2
• Denon PRA-1500
• Proton AP-2000

The Onkyo and Proton had the lowest list prices (in the $300 range), so they’re probably your best bet for a cheap solution.

Pre-amp/tuner combos are also an option. Here are the ones I could find that listed under $1000:

• Adcom GTP-450
• AudioSource Preamp/Tuner 2
• Carver CT-23/CT-24
• NAD 917
• Rotel RTC-940AX

Good luck and happy remoting!

Wayne
