Why is our JOB Better ?

The JOB Amplifier's Technology.

• The JOB Amplifier circuit is one of the fastest amp circuit in the world with nearly 3 MHz bandwidth !!!!
  Why is that speed so necessary?
  Because live music and speech are both essentially made of transients. And transients are only sounding accurate when they are rebuilt into the ear with exactly the time coherence they had initially. Only extra-large amplifier bandwidth can rebuild time coherence accurately.
  The audible effect ? A real frequency-balanced time response brings Intelligibility which is extremely important for the ear to recognize musical instruments, and understand speech. This is why it is so essential for Computer Games and Home-Theater applications. You have to understand a whispering voice in the middle of a large explosion !
• The JOB Amplifier is DC coupled with a new type of DC Servo Control avoiding any DC offset.
  DC coupling is the only way to avoid time error in low frequencies. It avoids the usual boominess of the speakers bass response. So you get Tight Bass.
• The JOB Amplifier is very powerful for its diminutive size: 210W on 8 Ohms per channel for the JOB 225. This is the perfect power for a small amp : enough power to respect the High Dynamics of real music and speech. The limited-power amps usually found in computer extensions are not able to reproduce these transients. Neither are the cheap amplifiers used in low-cost Home-Theater equipment. Be careful reading specification. When JOB means power, it's real power, not a marketing argument like it is too often in cheap designs ! You know, Swiss are making understatement one of their key marketing arguments..

To achieve these results, JOB uses high-tech solutions, more often used by space or military industry than by hi-fi manufacturers :

• JOB uses ultrahigh frequency printed board design with matched lines, constant impedance tracks, etc...
• SMD technology components are used as much as possible to shorten the signal path and increase the circuit speed.
• A minimum number of components are used in the signal path to minimize components coloration, specific distortion and group delay distortion.
• Only top quality or even military grade components are used : Minimelf German resistors, ultrafast capacitors including the latest development for filtering capacitors, etc...

If you are not convinced, look at the measurements. Here are some pictures taken of a high frequency signal reproduced by different amplifiers :

• The response provided by a highly-rated luxury Audiophile amplifier costing over $10'000 and weighting over 150 lb. !
• The tiny, inexpensive 1996 JOB's response.

The JOB Amplifier has other practical advantages :

• A very small size, allowing an easy location anywhere in a room, close to the speaker or on a computer desk.
• A light weight, allowing transport in portable systems.
• A very low level of magnetic radiation (use of high quality toroidal transformer) so the amp can be located close to a computer monitor or a TV set.
