Selling this unit for downsizing and streamlining my studio rack, works and sounds as it should!

This is the upgraded Ivory 2 (Series 2 / MkII) version of the 5013—a really nice unit to warm up digital samples and shape your tracks with real tubes. Always kept racked in the same studio location.

Specs:

Changes from Version 1 (MkI) to Version 2 (Ivory 2 / MkII):

• Push-Pull Peak/Shelf Switching: Pulling the Q knob on the LF and HF bands switches them from peaking to variable-frequency shelving filters (the MkI only had peaking filters on all four bands).
• "Fat" Contour Switch: Adds a dedicated per-channel contour (+2 dB at 50 Hz, -0.9 dB at 720 Hz, +1.8 dB at 10 kHz) to sweeten stereo mixes or drum busses instantly.
• Enhanced Tube Drive & Bypass Warmth: Features two valve stages per channel (pre-EQ and post-EQ) at 150V DC; the input tube stays active even with EQ bypassed to warm up signals, paired with new Drive and Peak LEDs.
• Redesigned DI & Line Circuitry: Upgrades the front-panel Instrument/DI inputs to a 1 MOhm high-impedance design and lowers the noise floor across the line-level I/O.
• Digital Expansion Slot: Adds a rear expansion bay for the optional DO-2 24-bit S/PDIF digital output card.

Other Specs:

• Form Factor: 2U 19-inch rack-mount chassis (483 × 200 × 88 mm, 2.5 kg)
• Valves: 2 × Sovtek ECC83 / 12AX7A twin-triode tubes (2 stages per channel, pre-EQ and post-EQ) running on a stabilized 150V DC supply
• Line Inputs: Electronically balanced XLR and unbalanced 1/4" TRS jacks, +/- 20 dB variable gain, switchable +4 dBu / -10 dBu nominal level (+26 dBu max)
• Instrument / DI Inputs: Front-panel 1/4" high-impedance (1 MOhm) auxiliary inputs per channel with -2 dB to +38 dB gain range
• Outputs: Balanced XLR (+26 dBu max, 47 Ohms) and unbalanced 1/4" jacks (+18 dBu max), with center-detented +/- 20 dB Output Gain control
• LF Band: +/- 15 dB, sweepable from 30 Hz to 1 kHz, variable Q (0.5 to 5), push-pull Q knob for Peaking or Shelving mode
• Low-Mid (LM) Band: +/- 15 dB fully parametric peaking, sweepable from 100 Hz to 3 kHz, variable Q (0.5 to 5)
• High-Mid (HM) Band: +/- 15 dB fully parametric peaking, sweepable from 1 kHz to 12 kHz, variable Q (0.5 to 5)
• HF Band: +/- 15 dB, sweepable from 3 kHz to 20 kHz, variable Q (0.5 to 5), push-pull Q knob for Peaking or Shelving mode
• Controls & Metering: Global EQ Bypass per channel (leaves input tube stage active), "Fat" contour switch, and Drive / Peak LEDs
• Frequency Response: 10 Hz to 40 kHz (+0, -1 dB)
• Dynamic Range & Noise: 106 dB dynamic range, -80 dBu noise floor (22 Hz to 22 kHz), less than 0.5% THD at unity gain
• Power Supply: Internal linear PSU (selectable 220-240V / 110-120V) with detachable IEC cable
