About Manley Labs Stereo Pultec EQ

Just imagine having the power to control your audio with precision and clarity. The Enhanced Stereo Pultec EQP-1A Equalizer, a high-quality product from the reputable Manley Labs, is designed to do just that. This professional-grade, dual-channel stereo equalizer is perfect for audio mixing and processing, offering a 3-band equalization capacity for superior sound control.

This innovative equalizer features two channels for stereo, both the PEQB and the SPEQ, offering transformer-coupled balanced output and direct capacitor-coupled unbalanced outputs for easy interface and sonic variety. The Manley input transformer with nickel laminations is potted in a mu-metal case, ensuring durability and long-lasting performance.

The Enhanced Stereo Pultec EQP-1A Equalizer is equipped with a Phase Reverse switch for balanced XLR input and an alternate transformerless 1/4" HI-Z (5K Ohm) input. It also includes a Bypass switch & Auto-Mute with warmup delay for added convenience. The silent conductive plastic Boost & Cut controls, along with sealed gold-contact Grayhill frequency select switches, ensure absolutely silent operation and long life.

This advanced equalizer is powered by a high-current drive and balanced Transformer-Coupled XLR Outputs via MANLEY 9611. It operates on mains voltage, with units purpose-built for the original destination country's mains voltage. Please note that the power transformer must be replaced to change the mains operating voltage.

The Enhanced Stereo Pultec EQP-1A Equalizer is Manley Labs' interpretation of the historic Pultec Equalizer, originally produced by Pulse Techniques, Inc. It employs a simple and clean all-tube make-up gain block to reamplify the signal after the passive EQ circuit. The EQ can be set to 'flat' positions or bypassed entirely.

This equalizer is housed in a single rack unit monoblock, occupying only one-third of the space of the 'antique Pultecs', making it a space-efficient choice for your outboard rack. It also features a rear-mounted input switch that selects 0 degrees or 180 degrees Phase Invert for the balanced gold pin XLR input or the transformerless unbalanced bridging input (1/4" jack).

The Enhanced Stereo Pultec EQP-1A Equalizer, available in both single and 2-channel versions, uses 1 x 12Ax7WA and 1 x 6414 (or 5965) in its all-tube single-ended line amplifier for the gain make-up and extra-beefy sound. Like 40dB Mic Preamps, the Manley Pultecs offer both transformer-coupled balanced and direct capacitor-coupled unbalanced outputs for easy interface and sonic variety.

Experience the power and magic of the Enhanced Stereo Pultec EQP-1A Equalizer and discover why it's a preferred choice for professionals seeking superior sound control.
