A150.4
Description
The A150.4 is compact power amplifier that fits in a 19″ 1U rack. This four channels power amplifier has been developed to drive four independent channels in fixed installations requiring limited space in the bays.
The A150.4 has a high efficiency thanks to his Class-D technology and can deliver 4 x 150 W RMS/4 Ohms or 2 x 150 W RMS/4 Ohms + 300 W RMS/8 Ohms(Bridged).
Inputs (balanced or unbalanced) can be connected to the Euroblock socket using the female free part connectors supplied with the device
Summary
- Class-D,
- 4 x 150 W / 4 Ohms or 2 x 400 W / 4 Ohm Bridged,
- Balanced inputs on Euroblock connectors,
- Speaker outputs on Euroblock connectors,
- 19″ 1U Rack
TECHNICAL SPECIFICATIONS
Crossover Frequency
Cut off frequency selectors for hi-pass (CH A, CH B) and low-pass (SUB) filters. The value can be set from 50Hz to 250Hz.
X-OVER FREQ is available in Mode 7 and Mode 8 only.
Mode selector:
- Mode 1: All channels stereo
All input and output channels are independent. - Mode 2: All channels parallel
All outputs are the same with channel input. - Mode 3: A/B bridged C/D bridged
Input the signal to channel A, connect the speaker’s “+” to the output A+, connect speaker‘s ‘-’ to the output B+. Then you get a 300W(8Ω) power. CH C and CH D are the same. - Mode 4: A/B parallel C/D parallel
CH A output and CH B output are the same whether input from CH A or CH B. The CHC and CH D are the same. - Mode 5: A/B stereo C/D bridged
CH A’s input and outputs are independent from CH B. CH C and CH D are bridged. - Mode 6: A/B parallel C/D bridged
CHA and CH B are parallel. CHC and CH D are bridged. - Mode 7: A/B stereo C/D SUB
CH A and CH B are stereo. CH C and CH D are bridged. SUB output signal is low frequency from CHC input. X-OVER FREQ is available. - Mode 8: A/B stereo C/D SUB
CH A and CH B are stereo. CH C and CH D are bridged and the device filters and amplifies signal A+B to feed the Subwoofer with the low frequencies only. X-OVER
FREQ is available. - Mode 9: Amplifier Mute
Amplifier is Mute.
