Guys, while we are waiting for Chris to complete the manual on Gizmo, there are some questions being asked.

I emailed Doug about 2 of the questions I have seen, and here are his responses ...

Q- Is the display on Gizmo supposed to flash - - when it's turned off?
A- Thats the default power up condition, Im not crazy about but I wanted some way of showing that power is applied. This can be changed very
easily.

Q- What is the difference between Standby and Mute?
A- Mute mutes the preamp stage and keeps the power amp running. Standby does this and power down the output section.

Also, Here is a graph of Gizmo at 25 Watts into 4 ohms.

We know the Gizmo has a high pass for the speakers. Does the Gizmo also do low pass for the subwoofer?

I'm looking at a Gizmo for a bedroom system w/TV and 2 M&K LCR650's.

Thus, my question:

Can it be left on all the time? Or is it recommended to put it in standby?...phrased another way... "Do i have to get out of bed to turn it off?"

As long as you can turn the source off, no worries. :salute:

Thanks Craig. The TV will be on a sleep timer

i'm using mine with rocket 250 sigs

First, the amp sounds terrific. Very clean. My office is small. Either I'm going deaf or the Gizmo is not playing very loud. Are the 250's just a bad speaker match? I read that the Gizmo powered those huge LS6's. I'm running at level 46 right now. Thanks.

The Gizmo I currently have is the prototype. My production unit is due in today or Monday. When it arrives, I have ELT-525, 250's, Ascends, etc ... etc ... to play with in a decent sized room. I think it is 22x13. You may be experiencing a problem with a source with a very low output voltage.

I will let you know what I find here, as the first speakers I will try out with mine will be the 250's. :smoke1:

Isn't it Schifter who says humblest apologies

Craig, you were absolutely right about the source. I am using a MAC and never realized the volume control in Itunes (maxed out) is independent of the overall volume control on the desktop (which was on half) With both now at their highest levels, Clapton's guitar is now rocking plenty loud -- and more important, plenty clean on my 250's.

I hope the current aggravation by unexpected tech problems (that will all be solved) doesn't take away the joy you should be feeling launching a great new product!

Congratulations!

Craig,

One of the things I noticed when I was testing my Gizmo was the sub out stays active when the Gizmo is put in the standby or mute mode. When you fix the sub out volume issue will you also allow the Gizmo turn off the sub out when in standby or mute?

Thanks,
Frank

1.What are the frequencies and widths of the bass/treble controls?

2.Did I read that there is a bass boost setting that counters the crossover rolloff for the case where the mains are low bass capable? If so, what boost number is that?

Thanks

Steve - Here is a graph of the bass boost.

Craig,

I had emailed you and Bill about the sub out issue on my Gizmo. I think I found the problem. I guess I just assumed the sub out was a low pass pre out. The sub I was trying to use it with only has a line or low level input. I was using it with a receiver that had a low level sub output.

Am I correct that the Gizmo sub out is not low level output?

Just to help out future customers, on the Gizmo product page might want to specify what type of sub output signal it has. I guess I just assumed since it was a RCA connection it was low level.

Other than that I've been real happy with the performance. Really hate not being able to use my sub though.

All,

Just wanted to give an update on my issue. Spoke to Craig on the phone yesterday and he was able to help me troubleshoot my system and figure out what was going on.

First the sub out is a low level output. My issue was just the opposite of Nala's in that both my computer volume control and Microsoft media player volumes were on max and overpowering my subwoofer amp. Once I lowered the volume level everthing started working perfectly. I now just leave the Gizmo volume up around "45" and just control the volume using either media player or system volume control.

Jammed last night to some good old rock and roll. AC/DC highway to hell was one and it rocked with my Cadence sub and AV123 ELT525M's.

Thanks Craig!!!! :thumbsup:

had the same issue, was cranking all the pc levels and keeping gizmo at 6 or so, changing it so I run Gizmo ~40 fixed the sub sounds with standby (x-sub)

PS Craig and team, this makes my XSLS-Encore and X-Sub system sing and works great.

Do you have the input voltage sensitivity specification for full power output from Gizmo? I looked at the website and did not see one. :no clue:

This is the best I could find until Craig answers for you.
