INTRODUCTION Thank you for your decision to purchase Stanton’s innovative new A Series professional power amplifier! Engineered for superior sound reproduction, the A Series line of professional amplifiers deliver top quality audio at an affordable price. The A Series offer a standard of reliability and efficiency that makes them the perfect solution for every DJ, musician, and sound engineer.
FRONT PANEL CONTROLS 1. Rack Ears These ears are used to mount the amplifier in any standard 19” rack. 2. Fan Vent The A-Series amplifiers are cooled by two rear-mounted fans (except for A.900 which is cooled by a single rear mounted fan). Cool air flows through the front fan filters, reducing the temperature internal components while forcing the heat out the rear vents. Never block these vents and keep them clean at all time. 3. AC Power Switch This switch powers the unit on and off. 4.
REAR PANEL CONTROLS 1. Fan This is a variable speed cooling fan. Cool air enters the amplifier through the fan filters located on the front of the amplifier. Be sure not to block these ports when installing the amplifier or other equipment. 2. Input connectors Connect the input source to the balanced combo connectors using either XLR or 1/4” TRS plugs. They are configured as follows : Pin 2 (Tip) hot, Pin 3 (Ring) cold, and Pin 1 (Sleeve) ground.
PROTECTION Every model in the A-Series incorporates protection features. The front panel Protection LED indicates the activity of the relay speaker connection circuitry in each channel. When the protection LED turns on, this circuitry is active, and all connected speakers are muted. Initial power-up : For approximately five seconds after initial power-up, the protection circuitry is activated and the speaker outputs are muted.
SETUP Mode Select CONNECTIONS Stereo Mode (5-Way Outut Binding Posts) Stereo Mode In stereo mode, both channels operate independently with individual input gain controls. Signal at channel 1’s input produces output at channel 1, while signal at channel 2’s input produces output at channel 2’s output. Recommended minimum nominal load impedance for stereo operation is 2 ohms per channel.
