Productbeschrijving
Audison SR 4.500 is a 4-channel Class D amplifier with a total power of 880 W and output powers of 130 W x 4 at 4 Ω and 220 W x 4 at 2 Ω.
The minimum impedance is 2 Ω in 4-channel operation and 4 Ω in 2-channel operation.
The integrated Crossover covers 50–3.2 kHz with 12 dB/oct.
for high-pass and low-pass.
There are Pre-In and Speaker-In with input sensitivities of 0.2–5 VRMS and 0.8–20 VRMS, respectively.
Features include PRE OUT Full Range, ART Automatic Remote On/Off, Remote IN/OUT, and built-in USS.
Controls include Bass Boost on channel B (0–12 dB) and Sub-CH level from −20 to +6 dB; optional VCR-S1 remote control for subwoofer level −20/+6 dB.
The housing has rounded corners and generous heat sinks without internal fans.
Bandwidth is 10 Hz–35 kHz, S/N ratio A 105 dBA, damping factor 200.
Power supply is 11–15 VDC with 2 x 25 A Fuses, weight 2.12 kg; dimensions A 264 mm, B 234 mm, C 155 mm, D 135 mm, E 47.5 mm.
