The A2D represents a landmark achievement for API: it is the first product ever produced by the company with an integrated digital output. Recognizing the desire for a high quality solution to raise microphone signals to a workable line level, we engineered one of our most popular mic preamp designs into an enclosure with our new proprietary analog to digital conversion. The result is a complete package - a pair of superb mic preamps feeding an A/D section with a set of standard digital interface outputs, multiple sample-rate choices and internal or external clock options. Precise control of both the analog gain as well as the level feeding the digital section means that the mic signal can be maintained super-clean if desired, or driven harder on the analog side for that whallop and impact that can only be achieved by driving the transformer into saturation for that historic API sound!

The A2D analog section consists of the circuitry contained in two, API 312 mic preamps, or one half of the popular 3124 quad mic preamp rack product. A level control pot with an expanded, 20-segment metering system shows precise mic gain levels. Control switches include polarity, 48v phantom power, input pad, 2:1 transformer routing and Mic/Line select. Each analog input contains a balanced, low-level XLR connector and a high-level line input on a 1/4 inch jack.

The Digital section of the A2D includes two level pots to adjust the feed to the A/D converters, each with a corresponding, 20-segment calibrated meter. A multi-position switch selects the desired sample frequency. The External Sync LED will light when an external clock signal is used.

Rear panel Analog connectors include an XLR input and output for each channel, as well as a balanced 1/4" TRS insert to the A/D converter. This allows the A2D to have external analog processing devices inserted in the audio chain (EQ, compression, etc.)

Digital interface connectors provided are SPDIF, single ended RCA connector and AES digital out on XLR. A coaxial BNC accepts external "Super Clock" which will illuminate the front panel EXT SYNC LED when locked.

In addition, there are a pair of 9-pin, D-sub connectors which allow the linking of multiple A2D units, all operating off the first sample-rate clock in the chain.

I agree with the previous comment here... One more great feature is the pad - DI a classic bass guitar with the gain maxed and PAD pressed in and you end up with that perfect bass tone everytime. You don't need anything else. It also works magic as Mic preamp. Versatile and for the price - untouchable.

If you own an interface with s/pdif or AES inputs, this is the best way to add two top notch preamps and professional converters for a reasonable price. One feature this box has that the other API preamps (512c, 3124, 212) lack is the 2:1 transformer switch. This button is pure magic if you're looking to add a lot of transformer saturation to your audio. What this means? Larger than life guitars, crunchy snare drums, and levelled bass tracks. The metering on this unit is very good as well. If you need a serious upgrade to your recordings, but only record a track or two at a time, the A2D IS the best buy out there.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
  • USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
