Laney CA SERIES Power Amplifiers OPERATING MANUAL V1
Laney 2 INTRODUCTION Congratulations on your decision to purchase a Laney amplifier. Laney products are designed with ease of operation as a primary objective, however to ensure you derive the best from your new amplifier, it is important you take time to read this user manual and to familiarise yourself with the control functions and facilities available BEFORE SWITCHING ON After unpacking your amplifier check that it is factory fitted with a three pin 'grounded' (or earthed) plug.
Laney 3 IMPORTANT SAFETY INSTRUCTIONS WARNING: When using electric products, basic cautions should always be followed, including the following. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17.
Laney 4 Indroduction The CA range of amplifiers use a new power output topology. This enables a design which has all the high efficiency benefits of a class D type digital topology but without the usual draw backs of poor distortion and difficult to control EMC problems. The CA design uses microprocessor-controlled high frequency switching of state of the art output power FETs. Most switching amplifiers work at frequencies of around 200kHz.
Laney 5 Input Wiring The CA amplifier is factory set to +4dB input sensitivity, and internally selectable to either 0dB, +4dB or 26dB system. Setting the input sensitivity requires the removal of the top cover. If in any doubt, consult a qualified service engineer. For details on changing sensitivity setting see page 13 The 1/4“ Jack and 3pin XLR inputs are wired in parallel, 1 2 3 Pin1. Ground Pin2. Hot Pin3.

Reset Button: Should the unit be connected in error and experience a continuous overload situation such as connecting the unit to an incorrect supply voltage or should the amplifier experience a catastrophic component failure then the reset button will trip. This will cause the unit to completely shut down and all power to the amplifier will be removed. Once the unit has tripped the reset button needs to be pushed in.

This will cause the unit to completely shut down and all power to the amplifier will be removed.
Laney 37 11 Power amp mode switch: The CA3000 is a four channel power amplifier, Arranged as channels 1,2,3 and 4. These are configured as two totally separate stereo amplifiers. Channel 1 and 2 are treated as a pair, Channel 3 and 4 are treated as a pair. These channels can be used:(A) Stereo Mode. All channels run independently (B) Dual Mono. One signal sent to both amps. (C) Bridge.
Laney 42 43 44 12 Speakon Connector Bridge Speakon connector for connecting external speaker. The signal present at this connector is determined by the power amp mode setting (48) for this power amplifier. The Bridge speakon connector should only be used when the power amplifier mode switch (48) is set to Bridge. When in Bridge mode the signal present at the connector is derived from the input of Channel 3. Speakon Connector Amp 3: Speakon connector for connecting external speaker.
