Benchmark MPA1 Rack Mount Black.

The 2-channel Benchmark MPA1 microphone preamplifier is meticulously designed to Benchmark standards of transparency, ultra-low distortion, and ultra-low noise performance. The MPA1 mic pre is a perfect choice for stereo pairs, ribbon mics, and any other application where audio purity is the goal. Pristine Input Stage The Benchmark MPA1 mic pre's input stage offers high-voltage headroom (+29 dBu) and single-stage gain control to maximize the signal-to-noise ratio. The MPA1 maintains superb noise performance across the entire gain range (74 dB) by utilizing precision-matched, low-noise, transistor quad-arrays. A servo-controlled circuit minimizes DC-offset and maximizes headroom. Complete Low Frequency Response The MPA1 exhibits exceptional low-frequency performance with a clever dual-capacitor AC-coupling design. This dual-capacitor design defeats the limitations of single-capacitor AC-coupling designs, achieving an exceptionally low corner-frequency with excellent subsonic phase-accuracy. Innovative Stepped-Resistor Gain Control The gain control of the Benchmark MPA1 is completely unique. The gain is controlled via a 38-position, switched resistor ladder, set up in a continuously rotating orientation via relay control. This gain control circuit offers 2 dB per step, 0-74 dB of gain without attenuation, and inter-channel gain precision of +/- 0.03 dB. A make-before-break scheme creates a silent switching circuit. Elegant Phantom Power Protection The transistor stage is protected from phantom power surges with an ultra-fast, multistage protection circuit. This circuit utilizes the high-speed capabilities of low-capacitance Schotky diodes and the high-current capabilities of TVS diodes to absorb the phantom power surges caused by shorts and plugging/unplugging microphones with +48V on. This circuit is pre-biased so that it is isolated from the circuit in normal operation and activated when a surge occurs.

Benchmark DAC1 HDR Silver.

The reference-quality Benchmark DAC1 HDR preamplifier brings together all the best features and performance of the award-winning DAC1 family with the convenience of intelligent remote control. The all-in-one stereo DAC1 HDR combines some of Benchmark's finest engineering accomplishments into a single preamp: the DAC1 digital-to-analog audio converter with UltraLock clock system, AdvancedUSB computer audio playback (USB DAC) interface, and the legendary HPA2 headphone amplifier. The DAC1 HDR preamp's unique remote control is built around Benchmark's new HDR-VC (High Dynamic Range Volume Control). Benchmark's pro audio product designs have achieved unprecedented sonic purity due to an uncompromising engineering philosophy: eliminate digital distortion artifacts, establish a pristine analog path, and maintain sonic integrity regardless of external factors. The DAC1 HDR continues this tradition of excellence. The DAC1 HDR preamp's remote control solution is an intelligent implementation of dimming and muting. The Dim (quiet) and Soft-Mute settings of the remote control can easily be adjusted independent of the normal volume setting. The DAC1 HDR remembers and recalls your specified 'Dim' setting. This feature is ideal for HDTV users, as it allows you to set your preferred 'Dim' level for commercials, etc. The 'Soft-Mute' function fades down the volume to the 'Dim' level before muting and smoothly raises the volume to the normal level after un-muting. With a generous offering of inputs and outputs, the DAC1 HDR serves as the heart of expansive media and entertainment systems, optimizing the signal path from the various sources to the amplifier. The DAC1 HDR will enhance the audio performance of your digital television, digital cable box, DVD/CD player, computer, music/media server, satellite radio, and any other device with a digital audio output. Also, the HDR-VC will control the pristine path for an analog source, such as a phono stage, FM tuner, iPod, VCR, tape deck, etc. All digital inputs on the DAC1 HDR (including the USB) feature Benchmark's jitter-immune UltraLock clock system. The USB interface operates with Benchmark's AdvancedUSB native 24-bit, 96-kHz USB technology. The DAC1 HDR features a high-current output stage designed to drive even the most difficult loads. Other features include selectable headphone gain ranges and an auto-mute function for muting the main outputs when headphones are being used. HDR-VC High Dynamic Range Volume Control The DAC1 HDR features Benchmark's HDR-VC (High Dynamic Range Volume Control). The HDR-VC is achieved with a custom-built motorized Alps potentiometer. The DAC1 HDR's motor-driven volume control maintains the dynamic range of the converter and audio output. In contrast, digital volume controls reduce dynamic range, and analog volume IC's introduce distortion and noise. The acclaimed DAC1 D-to-A conversion system Recording studios. ...details

Benchmark DAC1 PRE Silver.

The reference-quality Benchmark DAC1 PRE stereo preamplifier, headphone amp, and computer audio playback device (USB DAC), use the 24-bit, 192-kHz DAC1 digital-to-analog conversion (DAC) system. The DAC1 PRE is the culmination of years of high-precision analog and digital audio circuit design. Benchmark has achieved unprecedented sonic purity in their pro audio systems through an intelligent engineering philosophy—establish a pristine analog delivery path and eliminate digital distortion artifacts. The Benchmark DAC1 PRE continues this tradition of excellence.With 6 stereo inputs and 4 stereo analog outputs, the DAC1 PRE anchors expansive media systems and provides a pristine audio path from source to amplifier. The 6 stereo inputs include an analog input, a USB computer input, an optical input, and 3 coaxial digital inputs. The output section includes stereo XLR balanced, RCA unbalanced, and 2 headphone jacks driven by Benchmark's HPA2 0-ohm headphone amplifier.The acclaimed Benchmark DAC1 D-to-A conversion system Engineers and audiophiles have grown to rely on Benchmark for critical digital audio conversion for more then 10 years. They are consistently finding themselves engaged in the music when using Benchmark digital analog converters—engaged in a way that is rarely achieved with digital converters.The award-winning DAC1 PRE's superior performance has made it the 'Benchmark' of D-to-A converters. The DAC1 PRE gracefully merges the Benchmark DAC1 conversion system with elegant analog circuitry, Benchmark's HPA2 0-ohm headphone amplifier, and essential features and functions.Jitter-Immune UltraLock Clock System Benchmark's proprietary UltraLock clock system achieves an unprecedented immunity to jitter. Many modern (and expensive) converters suffer from significant jitter-induced distortion. If jitter is not effectively addressed, a converter will generate nonmusical sideband tones and digital distortion. Benchmark's highly regarded UltraLock clock system ensures that jitter is never a problem, even under extreme conditions. Even in the presence of extremely high input jitter, no jitter-induced artifacts can be detected on the outputs of the DAC1 PRE (using state-of-the-art testing equipment by Audio Precision). UltraLock will block more then 12.5 UI of jitter (@ 1 kHz). With the UltraLock clock system, the D/A conversion-clock in the DAC1 PRE is totally isolated from the clock of the digital audio source. The UltraLock clock system easily outperforms most well-designed two-stage PLL designs. The bottom line is this: Benchmark converters will consistently and faithfully deliver truthful audio without jitter-induced artifacts, no matter what variables are present.AdvancedUSB Audio Technology The USB interface of the DAC1 PRE operates with Benchmark's unique AdvancedUSB technology. Unlike many USB equipped D/A converters, Benchmark's AdvancedUSB technology supports 24-bit audio at sample rates. ...details
