Zbal =

R8

R1

x Zline = k x Zline

Where k is scale factor; k =

R8

R1

The scale factor k, dependent on the value of R8, is chosen to meet the following criteria:

·

compatibility with a standard capacitor from the E6 or

E12 range for Zbal

· |

Zbal//R8|<<R8 fulfilling condition (a) and thus

ensuring correct

anti-sidetone bridge operation

· |

Zbal + R8|>>R9 to avoid influencing the transmit gain.

In practise Zline varies considerably with the line type and length. The value chosen for Zbal should therefore

be for an average line thus giving optimum setting for short or long lines.
