Technical
G1 Mk II employs an advanced filter circuit which provides exceptional performance when coupled to the
rest of the signal chain of the Sub-Bass System. A second-order variable low-pass filter approximating a
Bessel function was chosen for its linear phase response, which equates to flat group delay. This means that,
unlike other filter functions, the amount of delay the signal is subjected to during processing is constant
through the entire pass-band, which improves the frequency response and allows for better integration
of the sub with the main speakers. An additional fixed second-order Bessel filter follows the variable filter,
removing unwanted midrange signals that, if left unfiltered, cause the midrange of the main speakers to
become muddy or congested. All filtering is performed in the analog domain using high-quality components
with tight tolerances to ensure the highest possible performance and consistency.
The amplifier is fully DC coupled to avoid phase shifts and compromises in its low end performance. It is
inherently stable and will retain its characteristics over very long periods of time – important in a unit
designed for an exceptionally long working life. These amplifiers are designed to withstand reasonable
abuse and overloads. If in doubt, please contact your dealer.
We believe that the importance of the electronics, cabinet and drivers being designed to work in harmony is
paramount. This belief allows G1 Mk II to achieve the highest possible level of fidelity.
Overload Protection
All REL Sub-Bass Systems are designed as true Sub-Bass speakers. They are designed to reproduce those
exceptionally deep notes that are felt as well as heard. This it will attempt to do at whatever volume level
you set. If set too high no damage should result because the built-in electronics will limit the cone movement.
This electronic control is called Set-Safe™. It constantly and instantaneously monitors the output from the
power amplifier and is totally transparent in operation until required. This means it has absolutely no effect
on the sound quality of your REL until an overload is detected.
