Effectrode Leveling Amplifier(LA-1A)

电子管 录音室压缩

产品概述:

Effectrode LA-1A的设计初衷只有一个——让音乐人和录音师可以毫不妥协地从音乐演奏中提取到每一个细节。电子管以其无与伦比的音色增强而闻名,为录音和现场演奏增添了温暖、深度和清晰度,Effectrode希望将其性能超越目前的限制,为此我们采取了“平行管板”设计。平行管板设计可以最大限度地抑制噪音,并提高乐器的信噪比。这是一种实现降噪的昂贵方法,但是它可以产生一流的音质,而不需要靠噪声门来妥协或通过均衡“削减”某些频率。平行管的设计从来没有内置到一个踏板中,这让LA-1A如此与众不同。

产品特点:

  • Peak Reduction旋钮设置临界值和信号压缩量。调整压缩或维持的一个良好起点在9点钟的位置,细微的调整将增强音符细节,营造出更饱满,更温暖的音色。当旋钮顺时针调整是,高音量的音符相对于低音量的音符将被降低,演奏动态会被压缩,这是很多乡村和放克音乐的标志性音色。

  • Gain旋钮提供增益补偿,匹配旁路和受影响信号的相对电平。当Peak Reduction旋钮完全关闭时(逆时针拧到底,无压缩状态),还可以提供+15dBu的电子管激励。

  • Boost旋钮提供额外的+6dB增益(在Gain旋钮之上)。红色灯亮时Boost为开启状态。

  • Attack和Knee旋钮允许定制压缩品质,以适应更具有挑战性的设备。比如,主动拾音器的五弦贝司、配备压电拾音器的尼龙弦吉他或钢弦吉他,以及更特别的扬琴、羽管键琴或者西塔琴。顺时针旋转Attack旋钮增加侧链的反应速度,即压缩响应的速度,Knee旋钮改变输入和输出的曲线,即LA-1A如何过渡到压缩——顺时针旋转LA-1A为限幅器;逆时针旋转LA-1A为压缩。

  • 当Dynamic EQ拨档在下面时,将提升LA-1A的高频动态。当Peak Reduction完全关闭时,Dynamic EQ处于非活动状态,当顺时针旋转Peak Reduction时Dynamic EQ的效果将越来越明显,十分接近美秒的12弦Rickenbacker音色。

  • 平衡输出可以直接将LA-1A连接到桌面声卡、调音台和PA系统。这是完全平衡输出和变压器隔离,消除接地回路和减少噪音。增益选择拨档(+6dB、+12dB、+18dB)可以将LA-1A与任何线路和设备匹配。三磁感应音频变压器也赋予了LA-1A自己的特点,以加强和优化直接输出的音色。

The Effectrode LA-1A is a formidable piece of guitar and bass hardware” – Vintage Guitar

DESCRIPTION

The Effectrode LA-1A Leveling Amplifier was designed with one purpose in mind: to enable artists and engineers extract every last nuance from a musical performance… without compromise. Tubes are renowned for being unparalleled tone enhancers, adding warmth, depth and clarity to recorded and live instruments and Effectrode wanted to push their performance beyond current limits. To that end we based our LA-1A on a parallel tube plate design – the type of tube circuitry only ever found in high-end tube phono preamp stages for turntables (remember those?).
Parallel tube design minimises the noise floor and maximises the signal to noise ratio of your instrument. It’s an expensive way of achieving noise reduction, as four identical input tube stages are required, however it yields stellar tone quality without the compromise of noise gates or ‘cutting’ certain frequencies with equalisation. The parallel tube design has never been built into a stompbox or even a professional studio leveling amplifier/compressor before, making the LA-1A something truely special.

FEATURES

  • Peak Reduction knob sets both the threshold and the amount of signal compression. When adjusting the compression or sustain a good starting point is the 9 o’clock position where subtle leveling enhances note detail, creating a fuller , warmer tone. As the knob is rotated clockwise the volume level of loud notes is reduced relative to quieter ones, squashing playing dynamics – this is the definitive sound of many country and funk-style guitar riffs.

  • Gain knob adjusts the ‘make-up gain’ and is used to match the relative levels of bypassed and effected signal. It can also provide +15dBu of tube boost when the ‘Peak Reduction’ knob fully counterclockwise (zero compresson).

  • Boost knob gives an additional +6dB of gain (on top of the make up gain) – this is useful when soloing on guitar or bass and can push the input stage of a tube amp into overdrive very nicely too. The ‘Boost’ footswitch engages (red LED lit) and bypasses (green LED lit) the boost.

  • Attack and Knee knobs allow the compression character to be tailored perfectly to suit instruments that are challenging to amplify or record. For example, active 5-string bass guitars, nylon and steel string acoustic guitars fitted with piezo pickups and even especially ‘difficult’ stringed instruments such as hammered dulcimer , harpsichord or tar . Rotating the ‘Attack’ knob clockwise increases how fast the side-chain reacts, i.e. the speed at which compression kicks in. The ‘Knee’ knob alters the input/output curve, i.e. how the LA-1A transitions into compression – rotate clockwise and the LA-1A becomes a limiter and counter-clockwise for compression.

  • When the Dynamic EQ toggle switch is in the ‘down’ position the LA-1A dynamically boosts high frequency material. With the ‘Peak Reduction’ knob fully counter-clockwise (zero compression) dynamic eq is inactive, however as the knob is rotated clockwise, and the pedal begins compressing, the effect becomes increasingly pronounced. Fabulous for jangly 12-string Rickenbacker guitar sounds.

  • Bypass Footswitch utilises quiet true bypass switching to minimse ‘pops’ or ‘thump’ when engaging the pedal and ensure there is no loss of guitar tone when the pedal is bypassed.

  • Balanced Direct Out ¼” TRS (stereo) jack socket allows connection of the LA-1A to mixing desk, computer soundcard or external audio capture device. This output is fully balanced and transformer isolated, eliminating earth loops and reducing hum to an absolute minimum and features a gain pad (+6dB, +12dB and +18dB) to facilitate matching with any line or instrument level gear . The Triad Magnetics audio transformer also imparts it’s own character to enhance and sweeten the direct sound.

  • External Select ¼” TRS (stereo) jack socket. This enables an external footswitch, such as the Fender® ‘Twin Reverb’ Amp tremolo/reverb dual latching footswitch), to be utilised for remote bypass switching and activating the tube boost.

  • Includes 12V Wall-wart Power Supply: High quality low-noise switched mode 12VDC at 1.5A wall-wart compatible with all our pedals.
