IMPORTANT CARE & SAFETY INFORMATION
As with all sensitive electrical equipment, your DELTA 2 microphone
should be treated with care and respect at all times. Here are a few tips
to help extend the life of your mic and keep it working at its best…
• When you’re not using your microphone, always keep it in its protective flightcase.
• Keep your microphone away from moisture, liquid, naked flame, direct heat or
powerful light sources, and take care to avoid any knocks or bumps. Do not
place hot or cold drinks near your microphone, in case of spillage or heat transfer.
• Avoid transferring the microphone from cold to warm environments as this can lead to condensation forming
inside, which will adversely aect its performance. Should condensation occur, leave the microphone to reach
room temperature before using it again.
• When recording vocals, ALWAYS use a popshield to help prolong the life of the ribbon element.
• Do not turn on phantom power before the mic is plugged in as this can lead to damage to the sensitive
components inside the microphone. Similarly, when you’ve finished using your mic, turn o the phantom
power BEFORE disconnecting the mic.
• Use a soft cloth to clean your microphone after use (especially when recording vocals or wind instruments).
Do not use any solvents, thinners, chemical cleaners or aerosols as they could cause damage to the mic body.
• Due to its mechanical nature, the ribbon element will naturally stretch over time (and the ribbon motor itself is not
covered by our warranty). If you notice the sound of your microphone becoming distorted or duller than usual,
contact us to arrange for a non-warranty ribbon replacement.
• If subjected to sudden impact or a sudden loud sound source, the ribbon may break or disintegrate completely,
resulting in no signal at all. Please contact us to arrange for a new ribbon to be fitted.
• Under no circumstances should you attempt to open or service the microphone yourself. There are no
user-serviceable parts to the microphone and it will invalidate your warranty and may result in danger to you
and to the mic. Contact us or your local stockist or distributor for advice and help if you need it.
• If your mic exhibits any unusual behaviour, noise, smell or smoke, STOP USING IT IMMEDIATELY, disconnect
it from any other device and contact us or your local stockist/distributor for advice as soon as possible.
All our microphones are designed and developed
here in the UK by SONTRONICS’ founder and designer
Trevor Coley. We spend a long time creating and
crafting our microphones with extreme care and
attention, and all our new models are beta-tested with
top artists, musicians and producers (including the
engineers at Abbey Road Studios) before they
go into production.
Each circuitboard is constructed using the highest
quality components to ensure that your microphone
delivers you many years of worry-free use.
The capsules in our condenser microphones are
diligently hand-made using gold-sputtered Mylar
film which is no more than 6 microns thick (seven
times thinner than a human hair) and then artificially
pre-aged to ensure stability and to also give each
microphone its specific characteristics
Our ribbon microphones employ a microscopically
thin strip of corrugated aluminium ribbon and the
most powerful rare-earth magnets to achieve class-
leading sensitivity and audio reproduction. They are
built with British-made circuitboards, CNC-engineered
metal parts and precision-moulded grilles made from
British stainless steel mesh. The APOLLO 2 stereo
ribbon mic uses a top-quality Mogami® cable with
premium Neutrik® connectors.
SONTRONICS valve microphones (ARIA & MERCURY)
also employ UK-made circuitboards and utilise
hand-selected, European-made (or vintage British-
made), dual-triode vacuum tubes chosen for their
consistency in delivering a balanced frequency
response without over-colouring the original signal.
Our ribbon, dynamic and valve microphones are
hand-built in our UK headquarters, where our
experienced engineers put all of our mics through
several levels of quality control tests using specialist
laboratory equipment to ensure they meet (and
surpass) a series of strict performance targets.
In-depth audio tests are also carried out to ensure
each mic is working perfectly.
You can be sure that your microphone has been
lovingly crafted, expertly put through its paces,
stringently tested and hand-packaged so that you
can simply plug it in and start making professional-
quality recordings straight out of the box. We hope
you enjoy your microphone!
