• CDT SQA-4140 is a superb four-channel amp constructed with 46Hz-3.5kHz variable 24db crossovers. The amplifiers are logically grouped into pairs for bridging and for the routing of filtered input signals appropriate for each of many configurations possible. Amplifiers 2 and 4 of pairs, 1+2 and 3+4 operate with the signal inverted allowing the choice between individual and bridge mode to be made simply by changing the speaker connections. A dedicated four-channel mixer for all inputs may be selected within the system also. Two input sensitivity levels provides for each pair of amplifiers. Amplifier inputs 3+4 can be filtered to include band-pass and bass EQ (up to 18dB bass-boost at 44Hz) and may optionally be routed to all four, amplifier channels. There are 54 basic switch configurations and many connection schematics allowing almost any installation to be configured.

• CDT SQA-2400 is a powerful two-channel amp constructed with a 46Hz-3.5kHz variable 24db crossover. The amplifiers are logically grouped into pairs for bridging and for the routing of filtered input signals appropriate for each of many configurations possible. Amplifier 2 operates with the signal inverted allowing the choice between individual and bridge mode to be made simply by changing the speaker connections. Input sensitivity level provides for each amplifier. Amplifier input signals can be filtered to include band-pass and bass EQ (up to 18dB bass-boost at 44Hz). This is a basic two-channel amp with a configurable line out for possible multi-amp configurations. This unusual feature allows internal electronic crossover of multi-amp configurations. All amplifiers are turned on from a signal from the head unit marked REM, signifying remote turn on.
