JDSLabs CmoyBB Headphone Amplifier V2.03
JDS Labs’s success is due to cMoyBB’s legendary bass boost switch. Switched off, your original audio signal is amplified. Switched on, bass increases up to 9.4 dB for a perceived 2x increase in bass volume.
PRINTED CIRCUIT BOARD (PCB)
Older cMoys use thin wires or protoboard to transfer audio signals. cMoyBB uses a carefully designed PCB with attention to detail that cannot be achieved in protoboard amplifiers, or even in circuit boards designed by experienced hobbyists.
cMoyBB handles more than twice the voltage of most cMoys and supports dual rail splitters. The result is over 200% higher power handling than the original cMoy! Decoupling capacitors on all power pins significantly enhance opamp stability and sound quality.
POWER INPUT JACK
cMoyBB’s power input jack allows you to power the amp from your desk. Optional charging support also provides convenient, integrated 9V NiMH battery charging.
Standard, 2x9V: Recommended for high volume listening with 120+ ohm headphones. Does not charge batteries. Battery run time is identical to the 1x9V edition. Higher voltage enables higher volumes for high impedance headphones
