A 500-Series module that captures the essence of the classic Pultec EQP-1A sound
One of the most venerated equalizers of all time, the all-tube Pultec EQP-1A has been cherished by recording and mastering engineers for its almost magical ability to improve the sound of nearly any signal running through it. Now, after considerable research and development, the A-Designs Audio EM-PEQ has captured the essence of the highly revered Pultec EQP-1A and placed it in the compact and popular 500-Series form*—with no compromise in sonics or build quality.

Dual Mono-Stereo, Pure Class A Opto-Compressor
The AD2044 features 100% discrete, pure class A signal amplifier configured with high speed current monitored optical control elements. These "invisible" opto elements enable the AD2044 to deliver totally transparent, low noise gain reduction within the minimalist signal path design. No VCAs are incorporated. Variable attack and release controls plus side chain access, provide unlimited creative control from soft compression to hard limiting.

Dual Mono, Pure Class A Parametric Music Equalizer
The AD2055 combines 100% discrete, pure class A signal amplifiers with state-of- the-art passive and active filter topologies. The AD2055's unique circuitry delivers very high resolution transient detail at the operational extremes of real world equalization demands. The AD2055 auto-bias DC servo loop control eliminates the need for all interstage capacitor coupling. The AD2055 breathes life into all musical performances!

Let’s take a look at the construction features of the dbx® 223XL. As you turn the controls you will notice that these units are extremely well built. The controls exude great precision, and the feel is a solid "click". Also, when you open the box, you won’t find the external power supply that accompanies most processors in this price range. That’s because we know how difficult external power supplies can be to work with and even though it costs a little more, we put the high quality power supply right in the unit.
