That is the only Markbass manual in the public domain. I worked for a large consumer electronics company before retiring (2009) and anyone could order a Service Manual or parts. Admittedly the use of integrated SMPS and Class D modules mean that the failure of one part requires a PCB replacement. That is expensive but that is no excuse for the lack of service information. This type of protectionism was outlawed some years ago in the motor trade so why should the electronics industry be different. Ashdown, GK, Marshalll, Alesis have all been very helpful to me in repairing amps effects units Behringer, Markbass and Soundcraft have all refused to supply Circuit Diagrams of Service Manuals. I have had one Markbass unit that has had to remain unrepaired because Markbass do not help the independent repairer.

Correct David. My mains voltage is close to 250 in Dorset and some amp modules don't like it. 253V is the upper limit and I had 240V module that did not always work. of course in Norway the mains could be down to 203V.

I have had a Vox AC30 Bass Combo and a Fender Bassman 50 in my day and by modern day standards they are crap.

I would not bother. Put an FMV tone stack in front of a decent SS amp and it will serve you much better.

The point I was trying to make was that, in my experience, if a Markbass, unit goes faulty you are in for a hefty repair bill. Only one authorised service centre. This does not always mean there is a problem. Music Tribe (Behringer et all) also have a policy, like Markbass (one that I believe is illegal), to withhold all service information form anyone but the Authorised Service Agents but at least the Beringer Service agent is as helpful as can be, subject to the constraints that Music Tribe hold them to. Its not about whether it does go wrong, rather that if it does, it is uneconomical to repair.

Alesis MIDIVerb 4 Price Drop £90 - *SOLD*
Chienmortbb replied to Chienmortbb's topic in Effects For Sale
I will just add that the Midiverb was very popular as it has a very natural sounding reverb and echo. I cannot comment on the Chorus etc as I only used the Reverbs and Echoes -
Markbass CMD 121P combo. Loud enough for stuff?

Just pray it does not go wrong. -
This is the Alesis Midiverb 4. An ideal addition to any studio, installation or live setup. I used it for years with a mixer (the inbuilt effects with most analogue mixers are poor). Comes complete with the Alesis power supply. It has a few scratches around the rack mount holes (rack rash) but is generally in very good condition. It can be used with a footswitch to turn effects on and off, although there was no footswitch supplied. Postage will be about £5. Sound On Sound review here https://www.soundonsound.com/reviews/alesis-midiverb-iv ALESIS say: "The MidiVerb™ 4 is the perfect effects processor for professional project studios and musicians who require an affordable solution for fully-programmable, high-fidelity effects. Its excellent effects algorithms produce dense, natural reverb, rich chorus, flange, delay, pitch effects and up to three simultaneous multieffects. The MidiVerb 4 offers 18 bit A/D and D/A converters and 24 bit internal processing for a 20Hz-20kHz bandwidth and 90dB dynamic range, making it ideal for digital recording. Plus, its valuable Auto Level Sensing™ feature can instantly set the optimum input levels...a great time-saver. MidiVerb 4's thirty-two effects algorithms give you a complete arsenal of fully programmable effects, many using true stereo parallel processing. You can take advantage of the 256 powerful programs with 128 spaces for user-created effects. With its easy-to-use graphic interface, programming your own effects is a snap. And by using MidiVerb 4's MIDI controller routing and assignable footswitch input, you'll have complete creative control over every aspect of your sound."

Chauvet OBEY 4 DMX lighting controller. Almost immaculate condition. Price includes postage. This is a 16/4 channel DMX controller. It controls lighting fixtures or groups that operate on 4 channels of DMX. Below is a picture of the actual unit. Specifications DMX Channels: 16 DMX Connectors: 3-pin XLR Strobe Rate: 0 to 33 Hz Input Voltage: 9 VDC, 500 mA (external power supply: 100 to 240 VAC, 50/60 Hz) NB the unit has 12V DC printed on it but this is in error. The Chauvet website confirms that the unit needs 9V dc. Weight: 3 lb (1.4 kg) Size: 12.8 x 5.5 x 2.1 in (325 x 140 x 52 mm) Approvals: CE What's Included External power supply Quick Reference Guide -
The story that one amp class is superior or inferior to another. Are the different? Yes when driven into severe distortion. We all go into the discussion with biases and preconceptions* but when blind listening tests are conducted you get a truer reflection of what an amp or audio system can achieve.. *except me of course 😇
-
Don’t let the truth spoil a good story.🤪

They look as though they would work very well.
-
Yes I sort of realised that just after I hit enter. So my savings pot has been started.
-
Oh Dear. I don't buy from BD so that's a problem.
-
Those backbeats look great but they are not cheap at $399US excluding everything. That probably equates to close to £500 including shipping, handling duties and VAT. In saying that, for me the need for the instant feedback as Billy Sheehan describes in the promo, probably makes them a necessity.
-
Ah keyboard players. So often they wonder why the rest of us are needed as they can do it all.

I have measured the frequency response of two Class D amps. One the Bugera BV1001M the other was an Ashdown MiBass 2. Both were well withing =/- 1dB from about 70 Hz to well over 10KHz when the EQ/Tone controls were set at 12 o'clock. The MiBass 2 has a more aggressive High Pass Filter and although lower powered was prbably more suited to my needs, of course I sold it. As for blind tests, I agree they are worthwhile but suspect you would be surprised at the results. We all hear as much with our eyes as with our ears and taking the visual clues out mean that the visual heft of bigger amps is negated.
-
I feel like Cameron and Brown here but I agree with Bill and Phil. The first problem to address is the cabinet vibration and the second is the type of feet. Ask Orange about that. Third problem is the foam/rubber mat underneath. It may restrict the airflow as some amps will draw cold air from below AND the case may become warm and the close proximity of the foam/rubber matting could stop heat escaping.

Yes power amp compression in valve amps sometimes allied to power supply sag in earlier valve rectified models. It leads to a more pleasing sort of distortion (compression is distortion). With solid state amps (most Class A/B, G,H and D) the amps keep getting louder until the start clipping which tends to sound harsher than from a valve amp. Some A/B amps use MOSFET outputs that distort/compress more like a valve amp, think Ashdown ABM and Trace Elliot SM. I suspect Handbox also use this topology.
-
There are always exceptions to every rule.
-
I have to disagree, the main benefit is a valve amp is its inherent compression.
-
There was a common misconception that the ICE in ICEPower meant "In Car Entertainment" when in fact it meant cool as ICE.
-
Class H is basically Class A/B but has a complex power supply/power stage design that can almost instantly use more power when required. Most of the Ramsa Amps I have owned were Class H and sounded great. All bar one now sold as they are too heavy to move around at 70.
-
Class C is not used in audio, it is designed for radio transmitters.
-
Just a thought. Would an ABM in a slightly narrower format be worthwhile? My cab is about 40cm wide and the overhang is an issue. The width was originally decided by the width of 19" racks but realistically very few us 19" racks now.
