Safety instructions Safety instructions Intended use This device is intended to be used for amplification and playback of signals from musical instruments with electromagnetic pickups. Any other use or use under other operating condi‐ tions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.

Safety instructions CAUTION! Possible hearing damage The device can produce volume levels that may cause temporary or permanent hearing impairment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment.

Connections and controls 7 [COMPRESSOR] Pressure switch for enabling the built-in compressor. The [ACTIVE] LED lights permanently during operation, when the compressor is enabled. The [ON] LED indicates that the compressor circuit is active and processes the signal. The signal level at which the compressor processes the signal is affected by the gain controls (the higher the gain, the more the signal is compressed).

In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conduc‐ tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°. HB-160B...

Plug and connection assignment Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise inter‐ ference. 1/4" TS phone plug (mono, unbalanced) Signal Ground, shielding XLR plug (balanced) Ground, shielding...
