Four channel preamp with ZDT
The ZDT preamplifier series is based on all new discrete circuitry designed
by David Blackmer, establishing a new standard of sonic excellence in
electronics. This exacting new standard provides frequency response from
1Hz to 200kHz +0.5dB, an incredible rise time of 0.27 microseconds and
distortion of less than 1 part per million (0.0001%) - eliminating all
possibility of sonic degradation. These preamps are so fast, so clean
and so transparent that you don't even know they are there. It is like
plugging your microphone into a piece of "wire with gain." You
will hear clarity and detail with the ZDT preamps that is not available
in any other preamp at any price.
Features
- Zero Distortion - less than one part per million
- Lowest Noise of any preamp on the market
- 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)
- No Electrolytic Capacitors in the signal path
- Greater Transparency with minimum signal path and minimum features
|
- High output level +33dBu
- 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
