The Zähl EQ1 Stereo Equalizer is a highly detailed parametric stereo equalizer occupying only two spaces in a 500 series rack. Each channel is equipped with a true bypass button, frequency selection and output trim/gain.
The HI band ranges from 2 kHz all the way up to 20 kHz with the option of being a shelf or bell curve EQ.
The Hi-Mid channel ranges from 600 Hz up to 6 kHz, engaging the button above the Q on this channel will change the shape of the EQ curve. LO-MID ranges from 200 Hz to 2 kHz, same as the high mid channel. Engaging the button above the Q on this channel will change the shape of the EQ curve.
The LO channel functions the same as the Hi channel, ranging from 30 Hz up to 300 Hz with the option of a shelf or bell curve EQ. Engaging the LO-CUT gives you a high-pass filter ranging from 25 Hz to 250 Hz.
The EQ GAIN button will expand the trim or gain of each EQ channel by 5 dB or 15 dB. I/O gain will boost the overall signal level either on the Input or Output of the EQ1 by 5 dB or 15 dB.
A true bypass switch will remove the EQ1 from the signal path entirely. The small O/L Signal LED allows you to keep an eye on a proper audio level into your DAW or Tape Machine.

Design Features
– stereo design for mix & mastering as well as voices & instruments
– highly musical design
– intuitive, user-friendly, self-explaining layout
– lowest noise and distortion signal paths built with highest quality components
– audio switching on EQ gain potentiometer zero position for bypassing unused stages
– no microprocessor, no clock pulses, sequential logic only

– SIGNAL LED (green) level present
– O/L LED (red) overload warning driven by 10 checkpoints throughout signal chain

HI EQ
– gain range +/- 15 dB or +/-5dB, bypass in mid position
– individual ON/OFF switch
– frequency 2 kHz to 20 kHz
– BELL/SHELF characteristic switchable for effective treatment or sensitive adjustment with very soft slope and ‘airy’ character

HIGH MID EQ
