VPRE 562A

Fuse Audio Labs released VPRE-562A VINTAGE TUBE AMPLIFIER. Based on the 562A which is a rare all-tube amp built around the early 1960s. Originally designed as a PA amplifier but often re-purposed as a bass or guitar head by UK bands from that era, the 562A delivers its signature tone through a Mullard EF86 gain stage, ECC82 phase splitter and two 6L6 push-pull pentodes as well as custom input and output transformers.

The plugin kicks serious life into your tracks, adding beautiful vintage vibes from the sixties or even some pleasing old school grit if needed. It rocks as a spice booster for guitar and bass, no matter if used stand-alone or in combination with full-blown amp simulation. Precisely because of its vintage roots it’s amazing how beautifully the 562A can beef up modern instruments, too.

In this video, I tackle my most ambitious electronics project to date: building a mic preamp.

My vocal processing chain for this song was as follows: Rode M5 (matched pair) into 2 DIYRE CP5 Preamps with the CTX Colour module. On the software side, I used Waves CLA Vocals (mostly to add some reverb).

Heritage Audio Improves 500 Series 73-style mic Pre-Amp with 73JR II

3JRII The 2021 Update

The 73JRII  is the 2021 update to the already classic 73JR, a true 73 style mic preamp in a single 500 series slot with some added features that will cover all the recording needs for engineers and musicians that don´t find the need to track with eq. European pro audio manufacturer Heritage Audio announced the availability of the 73JR II — advancing its already classic 73JR single-slot 500 Series true 73-style mic preamp module with additional features surely set to satisfy the most demanding of recording engineers.

  • Microphone input impedance: HI, 1200 Ohm minimum, LO, 300 Ohm minimum. Higher gain positions gradually have greater impedances, optimum for lo gain ribbon mics. Input is transformer balanced and floating.
  • Line input impedance: 10K Ohms bridging, transformer balanced and floating.
  • DI input impedance: Greater than 2 Megohms, unbalanced.
  • Output impedance: Less than 75 Ohms, transformer balanced and floating, to drive a load of 600 ohms (factory terminated).
  • Maximum output: Greater than +26dBu into 600 ohms.
  • THD: Less than 0.025% at 1 Khz, less than 0.05% at 100Hz.
  • Frequency response: 20Hz ( +0.3dB ) to 20Khz (-0.2dB)
  • Maximum gain: Slightly greater than 80dB
  • Noise: Less than -125dBu EIN.
  • Power consumption: 86 mA per rail @+-16VDC.

Compromises can be made when trying to adapt a 73-style mic preamp into the smaller 500 Series format fit for compact enclosures — such as API’s popular ‘Lunchbox’ (letting space-restricted discerning users choose to house however many modules they wish from a seemingly-endless selection of manufacturers) or, of course, Heritage Audio’s own OST range of 500 Series enclosures— but this is far from the case with Heritage Audio’s 73JR II. By boasting heritage quality through and through, it uses only discrete, through-hole traditional components combined with hand labour to create a great-sounding Seventies-vintage vibe. As a faithful three- stage, all Class-A 73-style preamp, it is the real deal, with Styroflex and tantalum capacitors used throughout, and no corners cut.

Indeed, it uses the full three-gain stage circuit for up to 80 dB of gain with noise of -125dBu EIN (Equivalent Input Noise) over all the gain positions, and a true 24v onboard power supply for identical performance and distortion point. The output transformer is a custom Carnhill, manufactured for Heritage Audio by the renowned British company concerned in its St Ives factory in Cambridgeshire, while the input transformer is another custom Carnhill, this time manufactured in Oxfordshire — the same one found in Heritage Audio’s higher-end 80 Series modules, in fact, so hugely impacts the musical mojo of the 73JR II as a direct result.

Readily saying all that, then, the 73JR II itself is an update to Heritage Audio’s already classic 73JR single-slot 500 Series true 73-style mic preamp module with added features surely set to satisfy the most demanding of recording engineers. Enter an all-discrete Class-A hi-pass filter, sweepable from 20 to 220 Hz — making it easier to tighten the low end without affecting desired frequencies; a LINE mode, allowing for reamping of prerecorded tracks — perfect for adding some color to lifeless recordings; and a D.I. (Direct Input) — itself automatically switching to DI mode when inserting a 1⁄4” TS cable — that is an all-discrete Class-A JFET circuit fronting the microphone transformer to provide all the color and weight anyone could conceivably ask for!

Finally, Heritage Audio has paid particular attention to power handling by implementing internal +24v slow-turn-on-regulation — hugely healthy for any 500 Series enclosure’s power supply since it keeps the 73JR II’s power independent from other slots.

Simply speaking, anyone adding a 73JR II to their 500 Series recording setup is assured of a real deal 73-style sound.

British-style B173 mkII and American-style B12A MkIII Pre-Amps

Boutique audio company Black Lion Audio announce availability of the B173 mkII and B12A mkIII — British-style (1073) and American-style (312A) portable preamps packed into convenient half-rack-sized units, respectively, allowing users to mix and match as they sonically see fit,

Simply speaking, Black Lion Audio’s B173 mkII is the most portable 1073 ‘British sound’ around! As such, it uses the same Cinemag input and output transformers that are found in the company’s ‘full-size’ B173 Quad mic preamp to duly deliver a whopping 70dB of gain, alongside a revamped gain stage and a lower noise floor for a cleaner, lower distortion sound.

Sonically, the front panel-positioned Hi-Z IN (high impedance input) brings a harmonically rich tone to guitars, keyboards, and synthesizers, while the stepped input 1073-style GAIN and variable OUTPUT LEVEL attenuation knobs allow for flawless control over transformer saturation. 48V phantom power and phase inverse controls round out the front panel with self-explanatory XLR IN (input) and TRS OUT (output) connections literally bringing up the rear.

Representing the most portable 312A ‘American sound’ around, Black Lion Audio’s B12A mkIII uses the same Cinemag input and output transformers that are found in the company’s ‘full-size’ B12A Quad preamp to duly deliver a whopping 70dB of gain — just like its B173 mkII half-rack-sized sibling. Similarly, the front panel- positioned Hi-Z IN input also brings a harmonically rich tone to guitars, keyboards, and synthesizers, while the stepped 312A-style input GAIN control allows for perfect recall. Remaining on the front panel, there are also 48V phantom power and phase inverse controls, plus an 18dB PAD, while the B12A mkIII’s rear panel-positioned XLR IN and TRS OUT connections mirror those found on the B173 mkII.
