6OPERATING INSTRUCTIONSPlease read the operating instructions before using the Hall & Collins Signature Echofor the first time to understand its features for the best results.The input sensitivity and impedance is suitable primarily for use with an electric guitar,however, other signal sources can be used provided the maximum signal level atthe input does not exceed around 0.6 volts peak (1.2 volts p-p), which could causeunwanted distortion. Keep in mind that distortion on loud signal peaks may not bevery audible with certain sound sources (eg. a distorted guitar) and certain soundreproduction equipment (eg. a guitar amplifier with limited bandwidth).The signal path throughout this echo unit is mono, as was the case with most of theecho units emulated by the Hall & Collins Signature Echo.Please refer to the diagrams below for identification of controls and connections.The amplifier should initially be switched off or set to standby so that it cannot producesound.Check the power adaptor mains input voltage specification is consistent with the knownmains voltage in your location. A socket adaptor may be required in some locations.Connect the power adaptor to a mains power socket. It is best to connect to the samemains power source as your amplifier.
