Protect your investment with aPlatinum Coverage warranty plan:
There are no products for the condition you selected. Please make another selection.
This instrument or product has been carefully played/used and returned to us in
virtually new condition, however its packaging may not meet the standards set by
the factory. Also, it no longer carries the manufacturer's warranty. If you're looking
for a virtually new instrument in possibly less-than-perfect packaging, this is
a great value. We feel so strongly you'll like what you see, we're including our
60-Day Satisfaction Guarantee on instruments and 30 days on accessories, to this used product making it a no-risk purchase.
Very Good: This instrument or product has been carefully played/used and shows few,
minor signs of use. In most respects it looks and performs like new and may be considered
equivalent to display units found in retail stores. Its packaging may not meet the
standards set by the factory and it no longer carries the manufacturer's warranty.
Condition 2 products are a terrific value and you can buy with confidence knowing
our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories applies to this used product.
This instrument or product is in good working condition but has one or more cosmetic
flaws beyond those of a Condition 2 product. These flaws are typical of an instrument
or product that's seen normal wear and tear, including incidental scratches, chips,
dings, dents or other imperfections. It performs just as well as a Condition 1 or
Condition 2 instrument/product. Its packaging may not meet the standards set by
the factory and it no longer carries the manufacturer's warranty. Condition 3 is
a great choice if you're looking for performance and value and not as concerned
with cosmetics. You can buy with confidence knowing our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories
applies to this used product.
This instrument or product is not in working condition and needs repair, but can
be brought back to full functionality with replacement of parts or some skilled
repair work. If you are a do-it-yourselfer or know a skilled repair person this
is a terrific value. Condition 4 products are sold AS-IS: they do not come with
a manufacturer's warranty and are not returnable.
This instrument or product has been damaged beyond what we judge is reasonably repairable.
It's best used for spare parts or to practice repairs on, and at this price Condition
5 products are sold AS-IS: they do not come with a manufacturer's warranty and are
Accidental damage, normal wear and power surges are no longer an issue with these comprehensive and affordable plans. We even pay to ship your gear for repairs. More details.
Covers much more than the original manufacturer's warranty:
Limit of Liability: The least of the cost of (1) authorized repairs, (2) replacement with a product of similar features, (3) reimbursement for authorized repairs or replacement or (4) the price that you paid for the product.

Benchmark ADC1 USB A/D ConverterThe reference-quality Benchmark ADC1 2-channel 192-kHz 24-bit audio analog-to-digital converter is equipped with Benchmark's UltraLock technology. The ADC1 is designed for maximum transparency and is well suited for the most demanding applications in studios and mastering facilities. A rugged and compact half-wide 1 RU enclosure also makes the ADC1 an excellent choice for location recording, broadcast facilities, and mobile rigs. The internal power supply supports all international voltages and has generous margins for over- and under-voltage conditions.The Benchmark ADC1 achieves outstanding performance over a wide range of input levels. Each channel has a 41-detent variable gain control, a 10-turn calibration trimmer, and a 3- position first-stage gain switch (0, 10, and 20 dB). Each channel has a two-position toggle switch that selects either the 41-detent pot or the 10-turn trimmer. Both the pot and the trimmer have a 20 dB adjustment range. In combination with the first-stage gain switch, these controls provide exceptional SNR and THD+N performance over a 40 dB adjustment range. The 10-turn calibration trimmer may be used to calibrate the ADC1 to precise studio reference levels. It may also be used to optimize the gain-staging between a microphone preamplifier and the ADC1.The ADC1 has four digital outputs (1 balanced XLR, 2 coaxial, and 1 optical). The optical output supports AES, ADAT, and ADAT S/MUX. The two coaxial outputs (Main and Aux) can operate simultaneously at different word lengths and even at different sample rates. The ADC1 has the flexibility to allow simultaneous high-resolution and low-resolution recordings. For example, the main outputs of the ADC1 can be set to 192 kHz 24-bits while the auxiliary output is set to 44.1 kHz 16-bits for a safety backup or CDR demo recording. Both the Main and Aux Outputs originate from the same A/D converter. All outputs are professional format.The ADC1 has a Word Clock output that follows the sample rate of the Main Outputs. The Word Clock output is active in all modes of operation.A multi-format clock input automatically recognizes AES/EBU, SPDIF, Word Clock, or Super Clock signals. This clock input is used to synchronize the Main Outputs. If desired, the Main Outputs may be driven from internal sources. The ADC1 will automatically revert to an internal clock source when the external clock is lost.The ADC1 has two clock modes: Auto and Internal. Both modes support 44.1, 48, 88.2, 96, 176.4 and 192 kHz. The Auto mode allows the ADC1 to lock to an external clock reference. In Auto mode, the ADC1 will follow changes in sample rate, and/or changes in the type of reference signal (AES, SPDIF, word clock, or super clock).When a clock reference is not available, the Internal mode must be used, and a sample rate must be selected (44.1, 48, 88.2, 96,176.4, or 192 kHz). When the Internal mode is active, the ADC1 is acting as clock master, will only operate at the selected sample rate, and will ignore any signal at the clock reference input. If Internal mode is used, all devices connected to the ADC1 digital outputs will need to be configured to lock to the ADC1. Use the clock output on the back of the ADC1 if the connected devices require word clock.The Benchmark UltraLock system is 100% jitter immune. The A/D conversion clock is totally isolated from the AES/EBU, SPDIF, ADAT, WC, and super clock interfaces. This topology outperforms two-stage PLL designs. In fact, no jitter-induced artifacts can be detected using an Audio Precision System 2 Cascade test set. Measurement limits include detection of artifacts as low as -140 dBFS, application of jitter amplitudes as high as 12.75 unit intervals (UI) and application of jitter over a frequency range of 2 Hz to 200 kHz. A poor-quality clock reference will not degrade the jitter performance of the ADC1. In addition, the AES/EBU receiver IC has been selected for its ability to decode signals in the presence of very high levels of jitter. The Benchmark UltraLock system delivers consistent performance under all operating conditions.The ADC1 is designed to perform gracefully in the presence of errors and interruptions at the clock reference input. The ADC1 follows an audio-always design philosophy. Audio is present at the outputs shortly after applying power to the unit. The ADC1 will even lock to and AES/EBU signal that has its sample-rate status bits set incorrectly. Sample rate is determined by measuring the incoming signal. Lack of sample rate status bits or incorrectly set status bits will not cause loss of audio.The ADC1 is phase accurate between channels, and between other ADC1 boxes when locked to AES/EBU or word clock reference signals. The word clock output from one ADC1 may be connected to the clock input on another ADC1 to expand the number of phase-accurate conversion channels.For mounting options, see RM Kit #485682, RM Coupler #485683, and RM Blank #485683.
