Author Topic: BIEMA Power Amp Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 09-22-2006 04:01 AM                     Hi Any of you guys heard of or used these power amps. They are supposed to be "engineered in the USofA:. They are selling pretty cheap on Ebay down here. They have the Q series Professional and the W series Professional. Cheers Ian  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 09-22-2006 09:27 PM                     Biema is made in china and I beleive in australia Hoyts is useing them I have heard they are very good  |  IP: Logged Cameron Glendinning Jedi Master Film Handler Posts: 845 From: West Ryde, Sydney, NSW Australia Registered: Dec 2005 posted 09-22-2006 10:57 PM                     Hi Ian. Yes I have heard them, they are imported by www.altronics.com.au. I have heard them in a P.A configuration in the Store Demo Room and all I can say is that they are not bad. I was impressed. I would like to test them some day. website says Q series is designed for mixed use including cinema. Does this have something to do with Bi Amping?  |  IP: Logged Ian Bailey Master Film Handler Posts: 317 From: Nambucca Heads, Australia Registered: Jun 2003 posted 09-24-2006 05:12 AM                     It says in the ad that they are "engineered in the USA"-does that mean the Chinese put them together with American screwdrivers?? They look really good and the price is excellent. It would be a cheap way to start Bi-amping. I'm going to Tri-Amp my home Hi-Fi speakers first and if that impresses me then I'll definitely get into Bi-amping some stage speakers.

Face it... none of the dimestore electronics outlet stuff is going to be of really high quality.....

All one has to do is look at who and where they are being sold.... Good equipment costs $$.

The sound in Hoyts cinemas is not as good as other companies. Even their new locations have problems (well the ones I have being to anyway).  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 09-27-2006 07:52 AM                     Mark I strongly dissagree with some of your comments There are many cases where cost vs performance doesn't justify using a particular product For what they are the Pyramid amps have proven reliable and suitable for the size of rooms they have been used in The Biema products have proven themselves where I have had limited contact with them Far better than Crown And on the issue of offshore then QSC should be in your bad books as the RMX amps are made in Asia  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-27-2006 08:26 PM                     quote: Gordon McLeod And on the issue of offshore then QSC should be in your bad books as the RMX amps are made in Asia Gord, My issue isn't offshore products... Just crap in a box offshore products. With the RMX's at least they are a QSC design and QSC quaity controled... actually they are very well made too. The Asians are also capable of building great stuff.

Cheers Ian  |  IP: Logged Cameron Glendinning Jedi Master Film Handler Posts: 845 From: West Ryde, Sydney, NSW Australia Registered: Dec 2005 posted 09-28-2006 10:02 PM                     mmmm cannot agree with you on that last post, did you ever hear the yellow brick that Associated Sound made, yuck!!!!!! no bass, scratchy highs. Many country cinemas still unfortunately feature them. Ian I have heard the Biema, It sounds to me like its worth trying potentially great value for money, sounded OK to me. Altronics to me seem to have an extremely high quality control, unlike Jaycar ect. Their own brand Redback tends to be badged Timpony speakers ect.(sorry about the spelling Mark) The photo in the above post is infact one of Marks pet projects, a recreation of a Krell Amp, I found on another web sight. The quality of his workmanship is first class . I value his opinion greatly.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-29-2006 08:40 AM                     Cameron..... No that IS the original Krell power amp,not one that I Kloned..... Thats a factory original KST-100(class AB). The one we are Kloning is very similar except it will be true Class A and it will deliver 160 watts into 8 ohms and double that power each time the load impedance is halved all the way down to 1 ohm. The pcb is now well along in the design stage with everyone hashing over what devices and the exact layout we will be using. With people from all over the globe bulding these and different types of parts available in different countries we have to try to include all options if possible. Its nice having all those REAL electronics engineers from all over the world over at that other web site assist us with their tips and pointers during the board design. We have done the KSA-50 and that has proven to be the most popular thread at the audio site with close to half a million views. I have sold close to 400 PCB's for building that amp so far. In case you're interested in building one the builders guide is here. Give it a min. to dwnload!
