1. Introduction Welcome to B! Thank you for choosing the amp one out of the AER bottom-lineseries. This series has been specially developed for the modern bass player who values performance, versatility and easy handling. Please take a few minutes to read through these instructions. We want you to understand just what the amp one can do and how to set it up so that you can get maximum benefit out of it.
2. Safety Instructions The following instructions help to minimize the risk of injury through fire and electric shock. 7. Never install your device close to devices with strong electromagnetic fields such as large mains transformers, electrical motors, neon illumination etc. Do not lay signal cables parallel to power current cables. 1. Read these safety instructions carefully prior to using the device. 8. There are no user-serviceable components inside your device.

4. Starting up 4.1 Cabling and Switching on Before connecting to the mains, please ensure that your local mains voltage is suitable for the voltage of the device (e.g. 120V in the USA, 230V in Europe). The relevant specs and safety symbols are printed on the rear side of the unit. Connect all cables as desired and switch the amplifier on. The green power control LED indicates operational readiness. 4.
5. Functional Characteristics 5.1 Mute The mute switch turns the appliance to mute as required. The function can also be activated by a standard footswitch (on/off switch). 5.2 Tone Control Networks As with all AER products, the amp three is fitted with an excellent basic tone thanks to the selection of components, circuits and pre-equalizations. In addition, various equalizer networks enable you to adjust the basic tone to suit your personal requirements.
level If you turn the balance control to the left (Fig. 2), the bass range is further increased, but the treble is decreased by max. 0dB. intensity max 5.3 Compressor A compressor is an electrical circuit (a device) which you can use to influence the dynamic behaviour of a signal. The aim can be, for example, to minimise the risk of distortion. In use the signal level change can be kept constant at a set ratio from a set threshold. The following figure illustrates the correlation.

Being part of the effect loop path, return represents the input for an external effect device (from the output of the effect device). Return on it’s own may also be used as quasi auxiliary signal input (-10 dbV).
