THE 20DB PAD
One trend in modern console design that DDA has chosen not to follow is the removal of the traditional 20dB pad in favour of a wide range gain control system.
The reason for this is mostly due to the use of microphone input transformers. Their position in the circuit is always before the input amplifier. Without a pad, the risk of saturating the transformer with high level microphone outputs is extreme, unless very large transformers are used.
DDA's philosophy places the 20dB pad before the transformer to eliminate the risk of transformer saturation.
