The EQ4M rides on extremely clean +-18v rails without the need of any supporting chassis or power source. Just plug it in and make music.
More power, means more headroom. The EQ4M has an extra 2v compared to the EQ4 and boosts headroom to +29 dBu.
The EQ4M offers more control with its true in/out bypass, a transparent INPUT ATTN (attenuator), and an extra 15 kHz selection on the AIR BAND. All controls are stepped (detented).
