LD400 pro not very loud

support@line6.com — Sun, 18 Mar 2012 13:33:23 GMT

I just bought the LD400 pro and it doesn't seem very loud. i have been playing in a band for about a month or so and we have just been playing in the basement since this is all of our first time in a band and the guitarist is powering through two 50 watt amps that have 4 speakers in them and he is playing full volume and i have my 400 watt set up with 2 10" speakers but for having 400 watts i have to play full volume just to hear me. now i don't know much about setups so i don't know if it is something i am doing wrong or if it just the nature of the beast, but i have noticed that my cord has been stepped on so the end is bent and stem is loose, i have not yet got a replacement but i have been using that cord the whole time so could that be it. plus i was wondering if it is the number of speakers we are playing through, because he has 8 6" and i have 2 10" but with the LD400 pro i think that there is a plug in the back called "extension speaker output" is that where i can hook up the line 6 410 cabinet? i was just looking for information, if it's could be a cord, the number of speakers, or just the way it is; i just want to learn this stuff. also looking at the book it says, "connect only to AC power outlets rated 100-120V or 200-240V 47-63Hz (depending on voltage range of the unit; refer to back panel)" now i have not looked at what is says and i down have it at home right now but i just figured it was a regular amp and plugged into the house outlet, so i don't know what is going on there.

External Cabinet for LD400 - excellent match

support@line6.com — Wed, 06 Mar 2013 12:59:30 GMT

After some searching I found a Yamaha 1x18 cab that looked like a good match for the LD400. I found a used one at Guitar Center in Illinois and had a local person measure it for me to be sure of the dimensions, particularly the width as the LD400 is just about 24" wide. My intent was to put the LD400 on top to get the controls up at eye level and the 2 x 10's at ear, and get a subwoofer on the floor. I bought and they shipped to my local store in Boston area for about a $35 adder on a $200 purchase price. Can't argue the shipping fee as this cab is "half a refrigerator".

It arrived and is even better than I imagined as it is black rug covered like the LD and has the same metal grill and is 24" wide. I may or may not remove the little Yamaha emblem that sits center bottom. It is 8ohms as prescribed by this community and the LD400's specs for an external cabinet.

Yamaha SW118V (the CW118V is same thing in black paint with acoustic foam behind the grill hiding speakers, only difference from the carpet SW.)

300W/600W/1200W Noise/Program/Peak (this is near perfect match with ample headroom)

30Hz - 2kHz (10dB and this low Hz extension down to rock-bottom is instantly audible)

8ohms

24 width x 25 depth x 28 height (it ain't small and does stick out from the wall the full 25", but perfect height for perching the LD400.

SpeakOn and 1/4" so go with SpeakOn-SpeakOn as that is what LD400 external cabinet output is.

Note Yamaha glossy states 22" width and this is why I queried GC salesman to measure prior to purchasing. Yamaha web folder states 24" width and this is correct. Glossy also incorrectly states height as 32" but web folder is again correct at 28".

http://usa.yamaha.com/products/live_sound/speakers/passive_speakers/concert_club_v_series/sw118v/?mode=model

(use 25.4mm to the inch for converting dimensions)

Ok, so now what is combined load on amplifier?

We have 4ohm internal 2 x 10" and 8ohm external 1 x 18" in parallel.

Math result is 2.7ohms which is safely above the 2ohm overheating trip limit on this amp. So don't be afraid to turn it up.

Power calculation is in the neighborhood of 630W combined: 400W for the internals and the 230W on the Yamaha.

I fully intend on leaving this in my basement practice area when I gig - too bulky to fit in my car and at 86lbs, I like my back the way it is, thanks.

To make sure the LD400 doesn't vibrate and fall off onto the floor (a lot of stuff in my basement does when I play loud...), I screwed 4 furniture discs onto the top of the Yamaha to locate/register the LD400's wheels.

Furniture discs are round, hard plastic, with carpet like material on the underside intended for protecting floors from couch legs, etc. Home Depot or Lowes for $5 set of 4.

I suppose you could remove the wheels from the LD400 too.

Cheers.

Rich.

HD400 removing the cover

support@line6.com — Thu, 14 Mar 2013 11:01:45 GMT

Hi everyone.

One of the front handles on my HD400 has lost a screw, so the handle swings around, and you can't pick it up at the front. It's in a flight case with handles, so I can pick it up fine, but stage crew keep grabbing it at the front and making it worse!

Has anyone had any experience removing the main cover of the amp in order to get to the inside. I'm going to do it myself anyway, but just after any advice or help to make it quicker!

Cheers

Lowdown HD400 B-Stock

support@line6.com — Sat, 09 Mar 2013 01:38:26 GMT

Received a HD 400 B-Stock bass head and it would not work with the speakers. The headphone out and XLR worked fine. When connecting the speakon cable to the 1/4 inch 8 ohm speakers it made a bump bump popping sound continually through the speakers. I had the unit turned down so thankfully it didn't damage my speakers. This amp was received as a B-Stock unit and I am wondering what is wrong with it. Has anyone experienced any software issues with the lowdown hd-400 bass amp head. What is the longevity of all this wonderful technology ? Any comments would be appreciated, thanks.

LowDown LD400 Pro Speaker specs

support@line6.com — Fri, 02 Dec 2011 19:51:57 GMT

Hi,

I have a LD400 Pro and the speakers and horn has burned out due to a faulty amp module.

What are the impedance/wattage specs of the horn and the 10 inch Eminence speakers?

(The Eminence speakers say 8 ohms and I assume they are rated for at least 200W each)

And when did you switch between Hi-Touch and Eminence?

Thanks for your assistance!

Lowdown presets

support@line6.com — Wed, 02 Jan 2013 16:20:49 GMT

I looked at the Lowdown presets document in the download section but this only gives a description of the preset and the style it is copying. Has anyone found a document showing the exact knob settings to use, to recreate a preset in manual mode?

Volume issue with LD300

support@line6.com — Wed, 09 Jun 2010 05:48:39 GMT

I just bought a new LD300 today and not sure if there is something wrong with it. The volume seems to be weak for such a powerful amp. For example I have the amp set on manual, the Channel Volume is at max and the Master is at max, the Drive is low/off, the amp model is Clean. I am sitting two feet from the amp and I would expect the volume to be extremely loud for 300w but it's just not and infact the tone is not at all clear, somewhat scratchy. I plug my bass guitar into my Line 6 spider III 75w unit and it's way louder.....am I missing something with the settings or could this be a faulty amp?

Can I use the amp from my LD300 to DI into a PA without the speaker cabinet attached?

support@line6.com — Mon, 14 Jan 2013 20:06:29 GMT

Hi, I am very pleased overall with my LD300 and have used it for several gigs. The only thing is, it's heavy, and for small to medium gigs, I thought I might as well go into the desk via the LD300. Then I wondered, if I was going to do that, do I need the speaker cabinet at all? I've detached the speakers and taken the amp out, and would like to use just the amp for it's sounds, and DI straight into the PA, meaning I don't have to carry the cabinet - will this work? I mean, could I damage the amp by running it with no speaker attached?

considering Lowdown amp HD?

Lowdown studio 110 - volume problem

support@line6.com — Sun, 06 Jan 2013 01:36:43 GMT

Hi,

I have a ld 110 for 1 year now, and its volume is dead.

The equalization is working, the models, etc. but suddenly I coudn't get enought volume.

Previously I had some trouble with the saved presets. I tryed to erase the memory many times but everytime

I turned it on, there was a preset running. But now, the volume is very, very low, a lot below the normal.

Anyone can tell what possibly went wrong with my combo?

Thanks everyone,

Augusto.
