Balanced cables

The audio inputs are equipped with XLR-terminals (male and female). Balanced signal sources shall

always be connected using balanced cables as shown in Figure 3. The benefit of a totally balanced

system is that any noise superimposed on the signal paths will be cancelled on the input. On the

other hand, when using an unbalanced system there is no control of the noise in the system. This

may cause a high level of out-band, high frequency signals to be applied on the input terminals. Such

high-frequency signals could cause the amplifier to be loaded by high output currents that may

increase the inter-modulation and result in an audible reduction of the overall sound quality.

Unbalanced cables

The DPA 6.4 is equipped with balanced inputs, but can be used with both balanced and unbalanced

control amplifiers. When connecting unbalanced signal sources to the DPA 6.4, a «special cable»

consisting of two inner-conductors and a shield shall be used. All conductors shall be terminated in

both ends as shown in Figure 4.

Authorised dealers of Dynamic Precision's products can help and advice you how to choose the

proper cables to be used.
