Benchmark Media ADC1 USB 2-CH 24/192 A/D Black Rackmount
The barrier between analog and digital should not limit the listening experience. Benchmark's digital converter technology maintains the sense of musical engagement that was originally present when the sounds were created. The life of the music is never lost in a quagmire of digital artifacts. The depth is never hidden, the image is never smeared. Benchmark converters always deliver faithfully and consistently exceed expectations. The ADC1 USB continues a tradition of excellence.
The ADC1 USB is a 2-channel, 192-kHz, 24-bit analog-to-digital audio converter with an unprecedented feature set. This converter was designed to consistently deliver reference quality conversion in "real-world" conditions. It features Benchmark's, jitter-immune UltraLock(tm) clock system and an extraordinary analog front-end.
Jitter-immune UltraLock
The UltraLock(tm) system delivers consistent, high-quality conversion even when slaved to a poor quality external clock. The performance of the ADC1 USB will not degrade when slaved to an external clock - a claim very few converters can make. Enjoy the convenience of a clock input that automatically recognizes AES/EBU, S/PDIF, Word Clock or Super Clock sources - all with the unsurpassed jitter immunity of Benchmark's UltraLock(tm) clock-isolation system.
Benchmark's Precision Analog Circuitry
Benchmark has a long tradition of building ultra-high performance analog circuits that are designed for maximum transparency. The ADC1 USB extends this tradition by pushing performance to the limits of today's technology. The analog front-end delivers low-noise, low-distortion, high-bandwidth performance over a wide gain range (45dB). Precise gain and calibration controls allow for accurate channel matching. Capture exact imaging, difficult transients and subtle details with stunning realism.
Intelligent Meters
The nine-segment, dual-range, digital LED meters enable high-precision level monitoring. Meter response times are matched to the response of the human eye so that every peak is clearly visible. All metering is fully-digital and is not subject to calibration errors. A peak hold function allows an infinite hold to verify that an over has not occurred. Dual ranges allow signal presence monitoring or precise headroom indication. The meters even use an upsampling technique to detect and display inter-sample peak overloads. This upsampled metering warns of potential overloads that may not be detected by conventional digital meters.
Flexible Digital Outputs
The ADC1 USB has a total of 5 digital outputs (1-XLR, 2-coax, 1-optical, and 1-USB). These can operate simultaneously at up to three independent sample rates. One of the coaxial outputs can be configured for 16-bit, TPDF dithered output. This unique flexibility allows simultaneous recording to a CDR while recording high-resolution to a digital recorder and a DAW. For example, the CDR may operate at 44.1/16 while the DAW operates at 88.2/24 while the digital recorder operates at 192/24. Backup and/or reference recordings can be created with ease, while high-resolution outputs are fed to primary recording devices. The optical output supports AES or ADAT formats at resolutions up to 192/24. In ADAT mode, high sample rates are supported using SMUX2 and SMUX4.
Benchmark's Advanced USB
Benchmark's Advanced USB solution provides a bit-transparent computer interface that is capable of streaming at rates up to 96 kHz/24-bit without installing any drivers. This reduces CPU loading, eliminates driver compatibility issues and greatly improves the reliability of the data transfer. Benchmark's unique, driver-less Advanced USB(tm) solution is compatible with Mac OSX and Windows 2000, XP and Vista. Benchmark's UltraLock(tm) clock system insures the audio will never be contaminated with jitter-induced artifacts from a poor-quality, computer-based clock. With the Benchmark ADC1, the performance of the USB interface matches the quality of the AES and ADAT interfaces. The convenience of a direct computer interface no longer comes with a performance penalty!
Consistent Performance
Often specifications only indicate how a product will perform under the most optimal conditions. The ADC1 USB is designed to deliver consistent performance even in adverse conditions. The ADC1 USB is fully specified at all gain settings, all sample rates, through all digital outputs and even when locked to a high-jitter clock signal. This performance insures reliable and predictable results in the "real world". A full list of specifications and performance charts can be found in the ADC1 USB manual.

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: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 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.
