• Standard types and custom design service to ensure optimum design without the use of taps which can degrade performance.
• Highest grade grain-oriented low loss laminated cores (M6)for minimal distortion.
• Highly sectionised interleaved primary/secondary windings to ensure the best possible high frequency and transient response
• Low insertion loss.
• Windings protected by end shields. Termination is by 12 inch colour coded leads.
• Amplifier impedance (4 or 8 Ohms etc) or different line voltages to your requirement.
• Auto wound, tapped and multi winding transformers available. Just ask for a quote.

POWER BANDWIDTH

Both Music and Speech types are designed to have excellent bandwidth and transient response the only difference being the frequency at which the maximum power can be handled without significant distortion.

NOTES ON SPECIFYING LINE TRANSFORMERS

To order please let us know the parameters listed below. Please call suppport for help with specification if necessary.

1. The power required by the maximum number of speakers driven by the amplifier.  It makes no difference to the transformer how many speakers are actually connected.  If the load used is less than the maximum, the current drawn from the amplifier is reduced but the voltage delivered from the transformer remains at 100V.
2. The nominal impedance at which the amplifier is designed to deliver this maximum power.  If you get this wrong the amplifier could trip because of be over voltage or over current.
3. The lowest frequency at which it is required to deliver the maximum power.  If you get this wrong the transformer will saturate and cause distortion.  Frequencies below the specified value must be filtered at -6 dB per octave.
4. If the speakers have taps for volume adjustment this makes no difference to the amplifier or transformer.  You simply use the proposed power setting of each speaker to arrive at  the maximum power.  Normally the maximum to allow flexibility.
   

MULTI WINDING TRANSFORMERS
We make several types of multi winding transformer to distribute varying levels to individual loudspeakers for Line Source loudspeakers etc.

TAPPED TRANSFORMERS FOR LEVEL ADJUSTMENT
Non-isolating (auto-wound) operating at the line level (100V or customer choice). Input and output taps may be used to provide course and fine adjustment eg: Input tap 0 or -2.5 dB and output taps in 5 dB steps giving 0 dB to -40 dB in 2.5 dB steps.
