Four Channel Zero Distortion Technology Preamp (1 rack space)

ปรีแอมป์ ZDT ที่มีรายละเอียดชัดเจน จำนวน 4 ช่อง ตอบสนองความถี่ตั้งแต่ 1Hz ถึง 200kHz (+ 0.5dB) มี Phantom 48V สำหรับไมโครโฟน และมีความผิดเพี้ยนน้อย ทำให้มั่นใจได้ในเรื่องคุณภาพเสียงระดับมืออาชีพ

The 4 channel Earthworks 1024 Microphone Preamp is based on the philosophy that extended frequency response and faster cleaner time domain performance, will yield more life-like results. The unit is housed in a 1U rackmount chassis.

Earthworks was formed by David Blackmer, the inventor of dbx, to realize his vision of upgrading the entire audio chain to new standards of sonic realism. To that end, the unit is currently the quietest preamp available, particularly evident when high gain is used in recording classical music.

Any change that an electric signal undergoes as a result of passing through electronic components is referred to as distortion - clipping heavy-metal guitar signals being an extreme example - but is not limited to clipping alone. For the audio purist, the goal is to have as little distortion as possible affecting the audio signal.

The 1024 with its Zero Distortion Technology (ZDT) delivers immeasurable amounts of all forms of distortion, with a frequency response that is flat and wideband. Further, the preamp provides the recording engineer with the ability to accurately capture sound exactly as it happens in any sonic environment. This still allows for making sonic coloration and textural choices at a later stage, while retaining the original, life-like recording.

Features:

Zero Distortion – less than one part per million
High output level +30dBu
Very low output impedance will drive long lines without interference or signal loss
True 48 volt phantom, polarity reverse & clip indicator
Separate XLR & 1/4” Phone (t-r-s) outputs, each with its own gain/level controls
1/4” phone connector output will drive balanced or unbalanced inputs
Full differential (balanced) from XLR in to XLR out – no internal conversion to single-ended
All discrete components; Class A amplification (no ICs in the signal path)
Greater transparency with minimum signal path and minimum features
