Any two channels may be used in the bridged mode for higher power (20W/8 Ohms or 12W/16 Ohms).
Thermal limiting is also integrated into the power amplifier, with an intelligent shutdown mode that minimizes thermal shock to the device under extreme operation. Each power amplifier is internally power limited to protect itself from short circuits, excessively low impedances, or highly reactive loads. The level control feeds a monolithic power amplifier. The input to the PA8 is fully balanced and RF filtered. This is particularly important when the PA8 is used in close proximity to microphone pre-amplifiers. The toroidal transformer generates less heat than a comparable non-toroidal type, and emits considerably less 60Hz energy. The heart of the power supply is a low radiation toroidal transformer. The PA8 uses a straightforward, low parts count design for long term reliability. The amplifier outputs are muted at turn-on and turn-off to eliminate transients.
#8 CHANNEL POWER AMPLIFIER FULL#
The PA8 is passively cooled, and features full short circuit and thermal overload protection. The PA8 8 Channel Power Amplifier is a unique single rack-space solution for zoned, distributed loudspeaker systems with eight separate power amplifiers, each with an output power capability of 10W (4 Ohms) or 6W (8 Ohms.)
Other features included on the MI128 are: Power Guard ® signal overload technology that prevents overdriving the speakers our Sentry Monitor ™ short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal BUS input & outputs to easily distribute a stereo signal to multiple outputs and/or multiple amplifiers individual channel inputs 12 Volt triggering capabilities and eco-friendly on/off signal sensing that turns the unit off if no input signal has been detected for a set amount of time or automatically turns the amp on when it senses a signal. Robust and efficient professional-grade amplifier AMPI-8150 is engineered to work natively with Crestron Avia DSPs to provide. Also located on the back are volume controls for volume balancing, along with 2 digital audio inputs (either coax or optical) that can be bussed, and channel summing circuits for easy mono signal distribution.
#8 CHANNEL POWER AMPLIFIER PLUS#
On the back are unbalanced inputs for each channel plus 2-pole Phoenix style push-in speaker terminals. On the front panel, multi-color LED indicators display the status of each channel. As a highly efficient Class D amplifier, it does not require noisy cooling fans to maintain nominal operating temperature.
Parallel, bridged and parallel-bridged drive modes with 70/100V/140V/200V and low impedance operation. Dante and OCA integration via OMNEO with fallback options. Fully integrated DSP with high-resolution 96 kHz processing and FIR Drive. It has installer-friendly physical dimensions and is 2U rack mountable via the included mounting ears (the mounting ears are removable for non-rack installations). 8 x 1250 W multi-channel installation DSP amplifier with digitally controlled PFC supply. It delivers 120 Watts into 8 Ohm speakers or 150 Watts into 4 Ohm speakers via highly sophisticated closed loop digital switching amplifiers that are paired with extremely robust power supplies to produce performance levels that are rarely achieved in distributed audio. 8 x 100-watt, 8-channel Power Amplifier for 70-volt Distribution Systems with 2U Rackmount Enclosure, Independent Channel Gain Controls, Highpass Filters, Clip Limiters, Bridge Mono Operation, and Q-SYS Networked Capabilities. The versatile MI128 8-Channel Digital Amplifier can be used in many applications ranging from distributed audio to home theater to stereo listening. QSC CX108V 8-channel 100W 70V Power Amplifier.
