BAE 1023L

BAE 1023L

500 series Microphone preamplifier with DI Input and Equalizer

The 1023L — based on the classic 1023 — takes the preamp and EQ from the 1073 and expands upon it with significantly more frequency options in the high and mid sections, even allowing users to play the mid bell curve directly against the high and low shelves where they overlap. The 1023L is completely handwired using Carnhill (St. Ives) transformers. It has the exact same mic/line preamp as the 1073, but with significantly more frequencies in the mid and high sections. Aside from simply offering more frequency settings to play with, these expanded EQ sections also allow you to play the mid bell curve directly against the high and low shelves where they overlap. This capability opens the tone shaping possibilities in very interesting and musical ways.

• High Frequency: +/-16dB shelving with selectable frequencies of 10kHz, 12kHz, 16kHz, 20kHz and 24kHz.
• Low Frequency: +/-16dB shelving with selectable frequencies of 35Hz, 60Hz, 110Hz & 220Hz.
• Mid Range: +/-12dB or +/-18dB peaking with switchable selectable centre frequencies of 160Hz, 270Hz, 360Hz, 510Hz, 700Hz, 1.6kHz, 3.2kHz, 4.8kHz, 7.2kHz, 8.2kHz, 10kHz.
• High Pass Filter: 18dB per octave slope, switchable between 45Hz, 70Hz, 160Hz & 360Hz.
• EQ Button: Switches the equaliser on or off
• Phase Button: 180°
