{"product_id":"sonifex-cm-bha-ifb-and-commenatary","title":"Sonifex CM-BHA | Belt Pack Headphone Amplifier With Limiter \u0026 Loudspeaker","description":"\u003cp\u003eThe CM-BHA is a portable, battery powered headphone amplifier for use in live applications such as in-the-field news reports. The unit can apply gain of up to +20dB to the incoming signal. The volume control simultaneously modifies the output volume and the input gain, allowing input signals in excess of +24dBu to be reproduced without distortion. The CM-BHA has an adjustable limiter to protect the listener from excessive levels indicated by a blue LED. The limiter is only enabled when an earpiece or headphones are used, and when it is activated by the toggle switch. It is disabled when no jack is inserted, allowing a higher volume to be passed to the speaker for “squawk mode” use.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWide signal range capability.\u003c\/li\u003e\n\u003cli\u003eTransformer balanced inputs \u0026amp;
