Allow the EQF-100 to warm up for at least 15 minutes before using it in your
processing chain. The tubes and other circuitry need time to reach an electronic
equilibrium before they will operate at optimal specifications. For the longest life, it is
recommended that you turn off the unit when it is not in use.
Please mount the unit in your rack, making sure that there is sufficient ventilation,
especially on the right and left side of the chassis. The EQF-100 will generate a
significant amount of heat; therefore, it is necessary to have good air flow to prevent
damage to your EQF-100 or any other pieces of gear housed in the rack with it.
The tubes in your Summit Audio EQF-100 have been intensely screened for
desired distortion and gain characteristics. We recommend that you do not replace the
tubes with “guitar amp” tubes. Please consult your dealer about availability of
appropriate replacement tubes. These can also be ordered directly from Summit Audio.
Please fill out the enclosed warranty card. If you have any questions about the operation
of your EQF-100, please do not hesitate to call our customer service department at 775-
782-8838 or contact us on the internet at: [email protected].
Specifications:
Note on specifications: Summit Audio is uncompromisingly committed to excellence. All
of our specifications are made with the latest technology and are UNWEIGHTED
measurements. What does this mean? When measurements are “weighted” (e.g. “A”
weighted, dB (B), dB C weighted, etc.), the measurement devices are basically EQed or
filtered before the measurement is taken. This filtering was developed so that sound
pressure level (SPL) measurements can more nearly match human’s non-linear hearing
characteristics. However, when used in noise, frequency response, and distortion
