Happy Sound Guarantee

Happy Sound Guarantee - 60 Day Returns Period

 

Purchasing an audio product on the internet is not the easiest of tasks when you can't experience the most important factor - how good does it sound?

We only sell quality products that we're happy to have in our own homes.

But we don't expect you to simply trust that the products on our site are good quality, so we've implemented a few things to help give you confidence.

Each of these individual guarantees and warranties have been wrapped up into the K&B Audio Happy Sound Guarantee!

 

THE HAPPY SOUND GUARANTEE

 

1. THE BEST Returns & Exchange Policy

Quite simply, if you are not happy with the quality of the speaker(s) that you buy from us then you can either;

 1) return all or part of your order and exchange or upgrade for a different system/speaker* or...

2) return them for a full refund

The only question we will ask is "Can we help you choose a different system/speaker?".

For full details on our returns policy please click here.

 

2. Extended Returns Period

We know that our products are often project based, we know you might be buying it now for installation a few weeks down the line.

So we've extended our returns period from the industry standard 14 days to an industry beating 60 days!

You can return the system for any reason during this period.** Please keep the packaging :)

For full details on our returns policy please click here.

 

3. Extended Product Warranties

Electronics are usually only covered by a one year warranty.

But we don't think that's good enough considering you have to cut holes in your ceiling!

We've managed to negotiate extended warranties with our best-selling brands that you won't get anywhere else.

 

Lithe Audio - 2 Year Standard, 1 Year Extended  = 3 YEARS TOTAL

Systemline - 2 YEARS TOTAL

KB Sound - 2 YEARS TOTAL

Monitor Audio Passive Speakers - LIFETIME

Q Install Speakers -  5 YEAR WARRANTY

Please check individual product pages for an accurate warranty length for that particular brand/product. If in doubt contact us on 02393 190955

 

4. FREE Tech Support

When you choose to buy from us at K&B Audio you'll also get access to free technical support before, during and after your project.

We can help you with project design, specification of projects, how to wire and install all of the systems we offer.

Once you have your system installed we can also help with how to use it, how to get the most out of it and anything else you need assistance with.

 

* upgrade costs must be paid in accordance with the prices shown on our website.

** unless the goods are damaged on delivery or faulty the return postage costs are to be covered by you.

The QED SS20 2-way parallel speaker switch allows you to switch between two pairs of speakers for your ultimate set up

It enables safe connection and independent switching of two pairs of speakers (in parallel) from a stereo amplifier 


FEATURES

  • Minimum Load Impedance - 4 Ω (Using Two Pairs Of 8 Ω Speakers)
  • Power Rating: 150 Watts Rms
  • Silver Plated Switch Contacts
  • Large Cable Entry Protected Terminals (3.95mm Dia)
  • Dimensions (Hxwxd): 55mm X 157mm X 155mm
  • Suitable For Use With WM14 Wall Mounted Volume Control

 

FAQ'S 


WHAT ARE THE DIFFERENCES BETWEEN THE SPEAKER SWITCHES IN TERMS OF IMPEDANCE?

All the speaker switches are configured so that if you use 8 Ω speakers the minimum impedance seen by the amplifier will be 4 Ω


 

WHAT ARE THE BENEFITS OF SERIES VS PARALLEL ?

The switches which have more than two sets of speakers use a combination of series and parallel switching to achieve the minimum impedance of 4 Ω no matter what combination of speakers are switched on. For the two way switches there is a choice between exclusively series or parallel versions. If you have 8 Ω speakers (and a 4 Ω min amp) you should always use the parallel switch. If you have 4 Ω speakers and a 4 Ω min amp you should always use the series switch.

 


ALL QED SWITCHES LOAD ON 4 Ω USING 8 Ω SPEAKERS. WHAT HAPPENS IF MY SPEAKERS ARE 6 Ω?

1. Check your amp – if it can cope with a 3 Ω load or less (and some can) then you are alright. The rule is you must always use speakers with double the impedance of the amp minimum. 2. If you only have two pairs of speakers then use the two way SERIES switch.

 


HOW DO THE SWITCHES DEAL WITH POWER, E.G. IF I HAVE AN AMPLIFIER WITH MORE THAN 150 WATTS?

These accessories use mains switches which are rated at 6A which means the max power they can handle is 288W given an 8 Ω load

 


IF MY AMP IS RATED 6-16 Ω SHOULD I REALLY BE RUNNING A 4 Ω LOAD?

NO, NEVER – you should use 12 Ω minimum speakers. You can get 16 Ω speakers though – but it may just be easier to change the amp.

 


CAN I USE THEM IN REVERSE E.G. AS AN AMPLIFIER SWITCHER (WE KNOW THE ANSWER IS NO, BUT WHY?)

NO – because the speaker switches are designed to have two sets or more of speakers attached to one amp, if used in reverse there is always the possibility of connecting two amps at once to one pair of speakers resulting in damage to one or both amps.


 

WHAT IS THE TECHNICAL DEFINITION OF 'TRANSMATCH'?

For the 5 way speaker switch we don’t use parallel or series switching but use transformer coupling instead. Again you have to use 8 Ω speakers minimum if your amp is a 4 Ω minimum amp. The impedance is then matched by the transformer (hence the name) so that a net 1.6 Ω load (all 5 sets of 8 Ω speakers switched on)is converted back to a 4 Ω load. One pair of speakers (A) is not connected to the transformer but is directly connected to the amp, these will be the main speakers. The four B pairs are connected via the transformer.
