Crest Audio Ci™ Series Power Amplifiers
The multi-channel power amplifiers has a hardware configurations of eight analog input channels and powered output channels. Each channel output is
individually selectable as low impedance or 70-volt constant voltage outputs. Adjacent pairs of channels are bridgeable. Input signals are connected via eight 3-position Euro
style detachable terminal blocks, and can be configured as balanced or unbalanced inputs. Amplified outputs are connected via four 4-position barrier strip terminal blocks with
screw terminals.
The power amplifier sections is of a highly efficient amplifier design yielding 200 watts per channel for the eightchannel configuration into 8-ohms or 70 volts. Bridged channel 400 watts per bridged channel pairs for the eight-channel configuration into 16-ohms or 140 volts. Frequency response at 1 watt under an 8-ohm load is 5 Hz to 20 kHz.
Each model configuration is capable of accepting and hosting either of two networked modules to support connection of CobraNet® or Dante™ networked audio transport streams of four or eight channels. Audio, control and monitoring signals are conducted to and from the power amplifier via Ethernet connections.
Attenuation controls for each channel are located on the rear panel, along with output impedance and channel bridging selection switches. Control voltage inputs are provided
for each channel to allow for external gain control. Fault outputs on each channel are provided to allow monitoring of the operation of individual channels. Power sequencing
connections are provided via three-position Euro-style connectors. Instantaneous Gain Modulation provide overload protection for each channel.
