The A 4154 and A 4156 series of amplifiers are a cost effective solution for demanding commercial audio applications. These non-bridgeable models are designed to be used as standard 2 channel or stereo amplifiers. The design incorporates a fan forced cooling system to ensure reliability under the most intense output drive conditions.
The protection circuitry employed in the design ensures the
integrity of the amplifiers under overload conditions. The circuit even
protects the amp when a total short circuit is applied across the output
terminals. The 'soft start' limiter will immediately shut down the output
drive in overload or short circuit conditions, then will gradually restart
when the fault condition has been removed.
Each channel includes its own recessed front mounted volume control and
standard rear panel mounted RCA & 6.35mm jack inputs. Output connections
are made via heavy duty binding posts or industry standard heavy duty
speaker connectors.

The Q series amplifiers are designed to be installed in the most demanding of commercial audio applications such as pub PA's, nightclubs, mobile DJ's, cinemas and sporting venues. They are uniquely contemporary in appearance and offer high fidelity performance as individual stand alone amplifiers or stereo amplifiers. Each channel is powered by an independent power supply with high efficiency toroidal transformer. They can be configured to operate in bridge mode (mono) providing up to a massive 1200W RMS power to an 8 ohm load (A 4170). They will provide full rated power at less than 0.1% total harmonic distortion.
The design incorporates a thermally cued fan forced cooling system.
The protection circuitry employed in the design ensures the integrity of the
amplifiers under overload conditions. The circuit even protects itself when
a total short circuit is applied across the output terminals. The 'soft
start' limiter will immediately shut down the output drive in overload or
short circuit conditions, then will gradually restart when the fault
condition has been removed.
Each channel includes its own recessed front mounted volume control and rear
panel mounted XLR & 6.35mm phono jack balanced inputs with selectable
sensitivities of 0.77V, 1.4V and 3.5V. This allows input signals from a wide
variety of source equipment. Output connections are made via heavy duty
binding posts or industry standard heavy duty speaker connectors.
