EQ-2

2-Channel Tube Equalizer

No other high end equaliser can offer the same degree of power and flexibility as the new TL Audio EQ-2. Like the C-1 and PA-1, the EQ-2 features a raven blue 6mm CNC milled aluminium front panel, General Electric US military specification valves and high retention gold plated ceramic valve bases, but we've also added two much-requested features: a peaking/shelving switch on the LF and HF bands, and drive/peak LEDs. The internal circuit design has also been refined quite significantly to produce an even fatter, smoother sounding equaliser.

The EQ-2 boasts two channels of fully parametric 4 band valve equalisation - which in conjunction with variable high and low cut filters offers unlimited control of any audio source. But that's not all - unlike many valve equalisers, the EQ-2 provides continuously variable frequency controls, so choice of frequency is not limited to switched selections. It also features a pair of the acclaimed TL Audio mic preamps (with phantom power), to enable high quality direct-to-tape microphone recording, and a pair of front panel auxiliary inputs enable a guitar or keyboard to directly access the EQ-2.

Another brilliant refinement is the "stereo mode" switch - when activated, the EQ controls of channel A automatically process the signal on channel B in an identical fashion - thus the audio signals through both channels have the same EQ applied to them: ideal for precise equalisation of stereo sources and overall mixes. Quite simply we believe that the EQ-2 is one of the best sounding and most versatile equalisers currently available!

The EQ-2 employs a total of six valve stages per channel: one in each of the four EQ bands, followed by a pair in the output stage. General Electric US military specification valves are used throughout, run from a stabilised 250v DC supply.
