Used / Vintage EQs

If youʼre in search of unique sounds, vintage equalizers are a good starting point.
Before the days of unlimited audio channels, vintage tube EQs and graphic
equalizers were used to shape the final mix and bring out individual instruments
within a mono track. Some of these techniques are lost today, but the gear lives
on in the Sonic Circus vintage EQ department, where you might find a racked
pair of EQs from a classic console, or a sophisticated parametric mastering unit.
Keep your ear on this space if youʼre a fan of unique sounds.

Fairchild Model 673 Dynalizer (Vintage)

Vintage Dynamic Equalizer This is a Fairchild 673 ‘’Dynalizer’’ Dynamic Equalizer. According to John Klett, it uses the same slow optical system as the Fairchild 661 and 663 and operates as an automatic loudness control, applying a Fletcher-Munson Loudness curve which boosts the highs and lows as the level drops. The 673 was a staple in Joe Meek’s studio in the early ‘60s along with the Fairchild 660 and 661 limiters.
