Heritage Audio RACK2 – 2-Slot 80 Series Frame The Heritage Audio RACK2 is a high-end powered rack frame designed to host two classic 80-series modules, providing a compact and professional solution for running vintage-style modules outside of large-format consoles. Handcrafted in Europe using the same ISEP mechanical components found in original 80-series consoles, the RACK2 ensures perfect compatibility and authentic integration of both vintage and modern modules. Design Concept The RACK2 acts as a standalone platform with integrated power supply and full signal routing for 80-series modules. Each channel features its own output control and illuminated phantom power switch for precise signal management. In addition, two discrete Class-A JFET DI inputs allow direct connection of instruments without external preamps. Integrated link buses (A/B) enable stereo linking of compatible compressor modules such as the 2264—ideal for professional bus processing.

Heritage Audio 6673 The Heritage Audio 6673 is a high-end single-channel channel strip in 80-series format, combining the legendary sound of classic British console circuits into a compact modular system. Designed for professional recording, mixing, and hybrid studio environments, it integrates a microphone preamp and equalizer into a complete analog processing solution. Built around a fully discrete Class-A circuit with custom Carnhill transformers, the 6673 faithfully recreates the character of classic 1073 and 1066 designs—enhanced with expanded EQ flexibility for modern workflows. Sound Character The 6673 delivers classic British console tone with added versatility. The microphone preamp provides up to 80 dB of gain, delivering a powerful and detailed sound with rich mids and a solid low-end. Driving the input stage introduces transformer saturation, adding harmonic density and analog depth. The integrated EQ blends the musical warmth of a 1073 with the flexibility of a 1066, offering both bell and shelving options for precise tonal shaping—from subtle corrections to creative coloration. Highlights ✔ single-channel channel strip (preamp + EQ, 80-series format) ✔ combination of 1073-style preamp and expanded 1066/1073 EQ ✔ fully discrete Class-A circuitry ✔ Carnhill input and output transformers ✔ microphone preamp with up to 80 dB gain ✔ 3-band EQ with extended bell and shelf modes ✔ high and low shelving plus selectable mid frequencies ✔ inductor-based filters for musical shaping ✔ switchable high-pass filter ✔ output control for saturation shaping ✔ compatible with all 80-series racks (e.g. RACK2 / FRAME8) Typical Applications ✔ vocal recording with classic console tone ✔ instrument tracking with integrated EQ ✔ drum and instrument processing ✔ building modular high-end channel strips ✔ hybrid and analog studio workflows Technical Specifications ✔ type: single-channel channel strip (mic preamp + EQ, 80-series module) ✔ circuit: discrete Class A, transformer-coupled ✔ gain: up to >80 dB (mic) ✔ EQ: 3-band inductor-based (1073/1066 hybrid) ✔ frequency response: approx. 20 Hz – 20 kHz ✔ max output: > +26 dBu ✔ THD: < 0.025% @ 1 kHz ✔ input impedance: switchable (LO-Z) ✔ inputs: mic (XLR), line (XLR) ✔ outputs: XLR ✔ format: 80-series module
