7. IEC Power Cord Receptacle

This is used to connect the AC power source to your equalizer. Power requirements: 115/230VAC, 50/60Hz

8. AC Voltage Selector

Set this slide switch to match your line voltage supply.

CAUTION: For new installations and portable sound systems, or in any situation in which the AC power is suspect, it is wise to confirm appropriate voltage and line polarity BEFORE connecting the instrument to the power source.

9. Fuse Holder

This fuse holder contains an AC primary fuse. This fuse should be replaced with the same type fuse when this is blown out. If they continuously blow, stop replacing the fuse and refer servicing to qualified personnel.

CAUTION: After checking the AC supply voltage, be sure that the correct fuse is in the fuse holder: 1 Amp for 100-130VAC and for 220-240V AC.

10. Ground-Lift Switch

This switch is used to disconnect the signal ground from the AC power and chassis earth ground. This switch should be put in the LIFT position if the speakers produce humming sounds caused by a ground loop.

11. Input/Output Connectors

See INPUT/OUTPUT CONNECTIONS section (page 5) for proper wiring of the XLR, 1/4” TRS and RCA connectors for desired active balanced or unbalanced operation.Paralleling inputs and outputs may be accomplished by using any of the 3 connectors.

Note: while you can use any input connector with any output connector, only one of these connectors is to be used at a time.

GEQ 215 specifications

The Nady Systems GEQ 215 is a powerful graphical equalizer designed to enhance the sound quality and performance of audio systems. Renowned for its versatile application in live sound reinforcement, broadcasting, and studio recordings, the GEQ 215 exhibits robust features that make it essential for audio professionals and enthusiasts alike.

One of the core features of the GEQ 215 is its 15-band equalization, which allows users to tailor the frequency response of their audio signals with precision. Each band offers a range of ±12 dB of gain adjustment, empowering users to effectively boost or cut specific frequency bands. This level of control is vital for addressing common audio issues such as feedback, resonance, and tonal imbalances, ensuring that every sound source in the mix shines through clearly.

The GEQ 215 utilizes a 1/3-octave frequency center spacing, allowing for fine-tuned adjustments across the audible spectrum, from 20 Hz to 20 kHz. This wide range ensures that both low-end and high-end frequencies can be manipulated effectively, making it suitable for various applications, including musical performances, corporate events, and public speaking engagements.

Another standout feature of the GEQ 215 is its user-friendly interface. The front panel is equipped with backlit sliders that provide clear visual feedback, making it easy to identify settings even in low-light environments. Additionally, the unit has a bypass switch, allowing users to compare the processed and unprocessed audio signal quickly, which is essential for making informed adjustments during live performances or studio sessions.

The GEQ 215 also boasts high-quality components and construction aimed at ensuring reliability and durability. Balanced XLR and 1/4" TRS inputs and outputs allow for seamless integration into various audio setups, minimizing noise and maximizing signal integrity. Its rugged metal chassis is designed to withstand the rigors of both touring and permanent installation, making it a reliable choice for any sound engineer.

Furthermore, the device incorporates advanced technologies that enhance its performance. With a low-frequency response that features a high-pass filter, the GEQ 215 can effectively reduce rumble and unwanted low-frequency noise. It also includes LED level metering for each band, allowing users to monitor signal levels visually, preventing distortion and overload.

Overall, the Nady Systems GEQ 215 stands out as a high-performance equalizer that combines superior sound quality, user-friendly operation, and robust construction. With its comprehensive features, it remains an invaluable tool for achieving optimal sound in any audio environment. Whether for a live concert or a recording session, the GEQ 215 is equipped to deliver outstanding results.
