All these circuits make the Model 230 the best sounding and most flexible, yet easy to use, voice processor on the market. On air or in the production room voices will be more intelligible, have greater presence and fullness, and have more consistent levels- all while retaining their unique characteristics.

Instead, the Model 320 gives you the popular more symmetrical while also adding clarity and body. Aphex Big Bottom and Aural Exciter that are proven to not only flatter voices but increase power, punch and intelligibility. As a real COMPRESSOR plus, they are also very easy to adjust.
Why You Shouldn’t Connect a 230’s Output to a Mic Level Input. DEPTH PARAMETRIC EQ The bottom line: you will get an unsatisfactory noise level. The Model 230 is designed to generate a line Lets you set how much attenuation the Works like a standard parametric band level output from a mic level input.
Voice artists are constantly asked for a more compel- they are heard at a constant level. A Model 230 used ling, louder track. TV promos, film trailers, even radio on each microphone will take care of this problem production voices need to be dense, fat, consistent perfectly.

This method and others The standard balanced line wiring recommendation are illustrated in Table 2. from Aphex Engineering is this: In the majority of cases maximum noise rejection occurs when the CONNECTOR WIRING STANDARDS shield is connected to the input ground only (espe- cially in locations with high levels of RFI).

Diagram 3 Balanced to Unbalanced: This configuration should be used with equipment incorporating a conventional active balanced output stage. Most non-Aphex equipment uses this kind of output stage because of its simplicity and low cost. Therefore, you will find yourself using diagram 3 fairly often when interfacing typical equipment together. In this case, the interface gain will be 50% down, giving a 6dB loss of level.
Sidechain Processing Another exclusive Aphex patent, Big Bottom, provides a stronger, more powerful bass, increased sustain and density with- out an increase in the peak output. While static bass-boost EQ’s and subharmonic generators will increase the bass energy level, the resultant large boost in peak level often increases overload distortion.
