It will accept inputs from Bass Guitars, Acoustic Guitars, electric Violins, Pianos, Keyboards and Microphones etc. It also features a quality music player system with cabinet compensation and adjustable tone controls to enable a balanced sound to be obtained across a variety of sources. At this point it will be worth understanding the various signal flows through the amplifier and what has been done to each in terms of compensation etc. Starting with the instrument inputs, Channel 1 flows through from either the input jack sock- ets or from the built in wireless receiver. In both cases the raw signal from the instrument is passed directly to the Left channel of the stereo codec and therefore into the computer at- tached to the B Social unless you are using the Apptek in which case the effected signal will be used. Similarly Channel 2 jack input is passed directly to the Right channel of the codec, once again the signal is in the raw state. It therefore follows that any controls on the B Social such as Gain and the EQ will not affect the recorded sound, All level settings etc. will be performed by the software you are using independent of the B Social. Any sound you have recorded or are monitoring can be accessed independently via the return from the codec. In this case the L and R outputs are internally summed and passed through the Audio channel, the input gains on the instrument channels should be set to Zero to do this. The more processing reduces the quality of any Audio signal carried out on it; it is recom- mended that the highest quality recording will therefore be obtained with a WIRED connec- tion in preference to the Radio system. When using the B social as an instrument amplifier you can use either instrument channel or both simultaneously, the mix is obtained by juggling the Input controls, at the same time it is possible to Jam along with tracks sourced either from your computer connected via the USB or via another device connected by the LINE input or by Bluetooth. Using the appropriate leads a CD player may also be connected via the LINE in. As before Direct WIRED connections will give the best results with a progressive loss in quality when using Bluetooth and Downloaded Audio. B-SOCIAL - USER MANUAL B-SOCIAL - USER GUIDE The Audio channel The Audio channel deals with signals from the Codec Return i.e. sound sent from the com- puter, Audio from the LINE in and Bluetooth inputs. All these sources are internally mixed at a fixed ratio and there exists a preference order within the mixer. Signals can be used from the Codec at the same time as signals from the LINE in OR Bluetooth: note that the LINE takes preference over the Bluetooth in the same way as the Wired input to Channel 1 takes preference over the Wireless system. The mix of these signals can be optimised by controlling the Output levels on the Source de- vices. A comprehensive 3 band EQ follows next and finally the Volume control for the Audio section. During its passage through this EQ the Audio is compensated for cabinet response to give a balanced sound with the EQ set Central , neither boost or cut and with any loud- ness and bass compensations turned OFF on any connected devices. Once again the best results will be obtained with any equalisers in these devices set to FLAT. At lower listening volumes or to compensate for room acoustics the Tone controls can be adjusted to either Boost or Cut the sound according to taste. At this point the signal from the instruments is split into two for the left an…
