SUBJECT: Bryston Speaker Cable
August, 2010
Hi All,
Bryston is pleased to announce the introduction of a Bryston Speaker cable.
The Amplifier/Speaker interface is a 'low impedance' connection. Therefore, in a speaker cable you are looking for low 'self inductance' (because inductance rolls off the top end) as opposed to 'low capacitance' required in the RCA or XLR analogue interconnect. For speaker cables we use a stranded 12 gauge linear crystal copper terminated with 'Heavily Gold plated' Spade lugs or Expandable Banana plugs specially made for Bryston if required.
A speaker cable should have very low series resistance (R), and series inductance (L), while shunt capacitance (C), is relatively unimportant in this low impedance, high current application. Shielding is almost a non-issue in speaker cables as signal levels are very large and circuit impedances very low. Speaker cables, however, should be kept as short as possible to minimize power losses and the associated dynamic compression of the music signal. If a choice must be made as to which of your cables should be made longer, always let the additional length be taken up with your interconnects.
The Bryston speaker cable utilizes Four 12-gauge multi-strand conductors of OFC copper with advanced insulation. Bryston SC4 speaker cable provides accurate signal transfer and an ideal match to any Bryston amplifier. It provides power and control for maximum performance especially over long lengths. The SC4 employs twisted combined opposing conductors (red and white) to positive and black/gray) to negative for very low self inductance. Also the cable can easily be configured for utilization in Bi-Wired applications.
