The new Digitech VTP-1 is indicative of one of the new trends in outboard processing gear: Multiple Functionality at a cost-effective price. The VTP-1 is a stereo (or two separate mono channels) tube microphone pre-amplifier with an equalizer and an 18-bit analog-to-digital converter all in one, two rack-space case.

The tube mic pre-amp stage uses a 12AX7 tube and features both gain and trim controls to precisely set the amount of gain and tube saturation. Both line and mic levels can be put into the VTP-1. So you can record a direct bass guitar or a line level synthesizer with the VTP. There are 48-volt phantom power, phase invert and 20db pad switches. There are also separate "retro" looking analog VU meters for each channel and a red "clip" LED. The VTP-1 has a signal-to-noise ratio of 100db with less than 0.02% THD. Frequency response is stated to be: +0 or -1db from 15Hz. to 300kHz.

The equalizer is a four-band type with two fixed and two sweepable frequency bands. Each band can be boosted or attenuated up to 15dB. The fixed low and high band sections are shelved at 80Hz and 15kHz. respectively. There is also a 75Hz low-cut filter. The post-EQ send and return loop allows for insertion of external processing equipment such as a limiter. You can also order the unit with transformer outputs instead of the active electronically balanced output amps.

Of most interest to me is the internal 18-bit A/D converter. You can now directly digitally record to your DAT or digital multitrack in AES/EBU or S/PDIF digital formats. Sample rates are selectable from either 44.1 or 48kHz. Digital output is simultaneous with analog output.
