Analog single rack unit packed with vintage sounds.

The Heritage Audio BritStrip is the culmination of 50 years of analog design in a single rack unit. Britstrip nails the sound of yesterday’s iconic recordings for today’s demanding engineers and combines a real-deal 73 mic preamplifier, an expanded 73 equalizer, a discrete Class-A DI and the infamous diode bridge compressor from the Heritage Audio Successor. It's essentially like chaining together a 73JR, 73EQJR and mono Successor but with added routing flexibility. The BritStrip starts with the same preamp as our 73JR, with a custom input transformer co-designed with Carnhill and exclusively made for HA. The preamp also features a custom Carnhill output transformer, which completes it’s all discrete, Class-A, 3-gain stage design. The preamp features 80 dB of gain, 20dB pad, phase reversal and an impedance switch for 1200 or 300 ohm input. The DI is also taken from the highly acclaimed design found in the Heritage Audio 73JR, an all-discrete Class-A JFET circuit in front of the microphone transformer, giving you all of the color and weight you could ask for. The DI also includes a passive thru output to feed a separate amplifier.

The BritStrip EQ features three Vinkor pot core inductors in the mid band and high pass filter sections. The mid band is great for sculpting fat and punchy snare, kick, guitars and vocals. The inductor-based low-pass filter, directly taken from the 73 design, lets you control out of range low end without affecting the quality of your desired frequencies. The high and low shelves have been extended to include a bell mode, making them more versatile than ever before. The diode bridge bus compressor needs little introduction, as it’s the same compressor found in the multi award-nominated Heritage Audio Successor.  With BritStrip, this powerful compressor design is perfect to use for tracking, thanks to its blend control and elaborate sidechain filter. This gives you plenty of tracking potential, as you can give instruments that “record-ready” dynamics as performers monitor. The compressor section provides plenty of sidechain flexibility, with five frequency options and an external input. If that's not enough flexibility, two BritStrips can have their compressors linked for the ultimate stereo tracking solution.
