VOLUME CONTROL As we said in the first pages of this guide, all DPA leave the factory calibrated with the same power and equipped with a pre-calibrated volume control on the rear. However, it is possible to connect an external potetiometer for each input, with which you adjust the volume of each single channel. - Page 9 BRIDGE USE To use this mode, two BF inputs must be connected in parallel and use a “+” of a output channel and a “-“ of the other (see image). Do not drop under 8Ω impedance. OPTIONAL TR150 OUTPUT TRANSFORMER TR150 is a autotransformer that allows you to adjust the DPA output impedance with lines that have different impedances.
