1. Introduction 2. Amplifier Overview Danley DSA power amplifiers have been designed Danley DSA125X4 amplifiers are half rack width, 1U format power amplifiers that can drive both conventional low to provide configurable, consistent and reliable high impedance (Lo-Z, 4Ω to 16Ω) loudspeakers and high impedance performance audio power amplification for residential, (Hi-Z, 70V/100V) transformer coupled loudspeakers. -

- Page 15 Configuration 5.4 Setup and Signal Routing Thanks to their network based configuration features, Danley DSA amplifiers offer considerable versatility in terms of sources, signal routing, installation zones and output modes. Inputs can be freely assigned to installation zones, and those zones assigned freely to the available amplifier outputs in either Lo-Z or Hi-Z modes.
- Page 16 Note:: Only dynamic microphones are suitable for connection. Phantom power for condenser microphones is not provided. Note: When configured in Hi-Z mode Danley DSA amplifiers operate in ‘bridged’ mode where the output of two channels is combined. • If necessary, adjust the input gain using the slider or up/ This means that the number of output channels available in Hi-Z down icons.

The GPIO connector pin functions are described in the GPIO Settings menu illustrated in Diagram 5l. The connection of GPIO based remote volume control and standby/mute are illustrated in Diagram 5m and Diagram 5n respectively.
