ART TPS II 双路 电子管 话放 带压缩 前级话筒放大器

2680720

ART DPSⅡ更新了ART以前的真空管话筒前置放大器，加入了输入阻扰连接可调功能，LED输入表，自选用话筒/乐器转换，浮动的OPL（输出保护限制）以及更多的电子管音色到DPS中。
两个高品质独立的前置放大器和局部反馈，连接浮动的V3（可变的，真空管，声音）12AX7A真空管增益级（这是为续性调节二者的浮动设置）和选取择模拟/数据的输出设置，此种新增强的话筒前置放大器能承受20DB的信号峰值，动态范围达120DB，并且几乎无任何的失真效果，LED输入表可随时监控输入放大信号的大小。
增强的真空管增益级的性能的提高维持着我们经典的温暖音色，而且增加了胆味，尤其是在人声、吉它、贝司以及原声乐器，增强型的OPL可以控制过敏，使之在发生削波之前就能恢复到正常水平，一个通用的插入回路，在每一个通道上都有一个通和的INSERT接口，他们可以为加入的外部信号处理器提供回路，或是直接旁路，或是为高品质的转换器提供回路，模拟信号和数码信号独立控制增益，数码输出可以优化这些单元达到与外部设备同步的效果。数码输出包括S/PD4F，TOSLINK或是ADAT（在前板上可供选择）格式，前面板上的A/D转换采样频率可从44.1KHZ到96KHZ之间进行调节，或同步ADAT，或是外部的时钏码（从32KHZ到100KHZ），并可以通过补丁程序兼容任何的ADAT数据流，或是选择一个或所有的DPSⅡ通道传输这些信号。
DPSⅡ与ART的横/戴转换，ART的真空管技术和ART的1/0前置放大器系统的技术相同，这样就保证了从横根的前置设备转换到数码处理时，信号将变得与你的期望是一样：胆味和乐感。

Designed as the ideal preamp for any application, the tube driven TPS II and DPS II add warmth and texture to any audio source. These two-channel high performance preamps use a hand selected 12AX7A tube in the low noise input circuitry. This, coupled with ART's proprietary V3?(Variable Valve Voicing) and variable input impedance allow the TPS II and DPS II to deliver incredible performance from cost effective single space rackmount solutions.

V3?Technology
V3?provides optimized reference points to begin the recording process. The V3?presets were created and fine-tuned by some of the industry's top studio and live-sound engineers. V3?technology allows you to select between a multitude of presets designed for guitars (electric and acoustic), keyboards, bass guitars, drums, vocals and more.

Variable Input Impedance
Variable input impedance increases the sonic potential of the TPS II & DPS II even further. It delivers entirely new sonic textures and tone by varying the input impedance of the preamp, which in turn varies the way the microphone reacts to the load of the preamp. This creates a wide range of new sonic possibilities with any modern or vintage condenser, ribbon or dynamic microphone.

The variable impedance control is infinitely variable allowing much finer control and the ability to tune the preamp to the microphone抯 ideal sweet spot. A feature usually only available on far more expensive and exclusive microphone preamps.

Extremely Wide Dynamic Range
The DPS II and TPS II can accept up to +20dB peaks while maintaining over 120dB dynamic range with incredibly low distortion. Input LED metering monitors the signal level of the input amplifier so maximum gain can be achieved without clipping the preamp at the input.

OPL?(Output Protection Limiter)
ART's OPL?(Output Protection Limiter), which precisely and accurately controls and maintains the output peak signal. The OPL?circuitry is crucial in protecting the next link in a signal chain - such as a hard-disk recording system or a sound card - because unlike analog clipping that sounds musical and sometimes pleasing, digital clipping is nasty and often fatal for your monitors?tweeters.

A versatile insert loop on each channel provides access for additional signal processing or direct access to our high quality A/D converter. Separate gain controls on analog and digital outputs allow you to optimize the unit for simultaneous applications.
