If you’re looking for a microphone that captures its subjects accurately, with a complete low-end response and a smooth, beautifully detailed high-end presence, then the HELIOS is for you. This precision allows you to transparently position your subject within a mix, without having to resort to heaps of EQ and dynamics processing to do the job for you.

The HELIOS is a triumph of design.

Like its sister, ORPHEUS, the HELIOS uses the same highly sensitive 1.07" dual-diaphragm capsule, but also employs the inherent warmth of valve circuitry.

If you’re looking for a microphone that captures its subjects accurately, with a complete low-end response and a smooth, beautifully detailed high-end presence, then the HELIOS is for you. This precision allows you to transparently position your subject within a mix, without having to resort to heaps of EQ and dynamics processing to do the job for you.

In our laboratories, we have spent many hours working with some very famous vintage microphones in order to understand what makes them sound so nice. As a result of this research, the gain structure and frequency response of the HELIOS has been engineered to closely simulate these characteristics, without adding unnecessary noise or colouration to the sound.

The SPS-1 power supply has a variable pattern control allowing a smooth transition from OMNI to Figure 8 pattern, and anything in-between. Allied to this are switches for a low-cut filter and -10dB pad, making the HELIOS one of the most flexible microphones available in any class. We’ve even added a TUBE READY light - in cool blue, of course - to let you know when you can start working.

Again, we felt that this microphone should have a special name, something with relevance like the ORPHEUS. Greek mythology heralds HELIOS as the god of the sun, bringing light and warmth to the earth. We think that this fits the personality of this microphone perfectly…

The microphone is supplied in a luxury wooden box and, together with its power supply and cables; it is protected by a high quality aluminium flight case.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
