The TL Audio EQ-2 is a high-end equalizer offering the same degree of power and flexibility. Like the C-1 and PA-1, the EQ-2 features a raven blue 6mm CNC milled aluminum front panel, General Electric US military-specification valves and high-retention gold-plated ceramic-valve bases, but TL Audio also added two much-requested features: a peaking/shelving switch on the low-frequency and high-frequency bands, and drive/peak LEDs. The internal circuit design has also been refined quite significantly to produce an even fatter, smoother sounding equalizer.
The EQ-2 boasts two channels of fully parametric 4-band valve equalization-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 equalizers, 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 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 equalization of stereo sources and overall mixes. The EQ-2 is one of the best sounding and most versatile equalizers 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 stabilized 250v DC supply.
