5.3.1.2 High SPL Profiles
High SPL profiles do not use the adaptive release time feature. High SPL profiles optimized for high frequen-
cies use less of the look-ahead delay peak-rounding feature; this feature is used most in the Sub profile and
least the HF profile.
▸ Sub - The Sub profile is optimized for frequencies between 20 - 200 Hz
▸ LF - The LF profile is optimized for frequencies between 20 - 1200 Hz
▸ MF - The MF profile is optimized for frequencies between 300 - 6000 Hz
▸ HF - The HF profile is optimized for frequencies above 1 kHz
Table 5-3 shows the theoretical maximum output power for a given load impedance and ISVPL setting.
An ISVPL-to-load calculator that will assist in generating the
appropriate ISVPL setting for a desired power load is available

Load Impedance (ohms)
ISVPL SETTING (V peak)
These ratings shown in Table 5-3 are limited by the
CPL (Current Peak Limiter) functions, not by ISVPL
settings, due to power output channel current
capacity.
