Dolby Lake Processor Model LP4D12 4in 12out Loudspeaker Management Description: Dolby Lake Processor Model LP4D12 4in 12out Loudspeaker Management Today up for sale I have a Dolby Lake Processor Model LP4D12 4in 12out Loudspeaker Management. This unit is loaded with 1 x XLR 4 channel Input card and 3 x XLR 4 channel Output cards. The Dolby Lake Processor marked the next generation in digital loudspeaker and equalization technology. With unsurpassed audio quality and the most advanced loudspeaker processing available, it will improve the sound of any system. Effortless control is provided through the Dolby Lake Controller software, or the exclusive front-panel Portal metering and control interface. The Processor platform offers complete, native-digital signal processing functionality, with support for up to 4-in, 12-out loudspeaker applications and 8 in, 8-out EQ applications. The signal processing can also be changed to provide an EQ 4×4 configuration together with a loudspeaker 2×6 configuration. The Processor includes several advanced technologies for improving sound quality. These include Raised Cosine Equalization (the foundation underlying the Ideal Graphic EQ and Lake Mesa EQ interfaces), plus linear phase crossovers, LimiterMax loudspeaker protection, and Iso-Float ground isolation.
PA amplifers(public address amplifiers) have two types of loudspeaker outputs,one is constant resistance with 4-16 ,the other is constant voltage with 70V/100V
MARK LEVINSON 533H USED------5000$ The No 533H shares the same basic amplifier module as the No 531H and No532H but is a semi-monoblock design. With power supplies that can be shared across multiple channels, this design lends itself well to multi-channel environments where one channel might need more power at times than others. All other features of the No 533H are identical to the No 531H and No532H and the common design creates a consistent sonic signature for use in multiple amplifier system configurations. SPECIFICATIONS Inputs one balanced XLR input per channel; one unbalanced RCA input per channel Speaker Connections one pair “Hurricane” loudspeaker outputs with banana-plug sockets per channel (banana-plug socket not available on the 230 VAC models) Communication and Control one Ethernet 10Base-T port; one 3.5mm mono (tip/sleeve) mini plug trigger input, 3-12Vdc; one 3.5mm mono (tip/sleeve) mini plug trigger output, 3-12Vdc; 3-pin IEC standard power connector Rated Output Power into 8 ohms 300W/ch (20Hz to 20kHz at 85dB, reference level: 2.83 Vrms Input Sensitivity 2.83Vrms output at 130mVrms input Gain 26.8dB Input Impedance 60 kO (balanced); 30 kO (unbalanced) Power Requirements 100V~, 120V~, 230V~, factory set for destination country; Power Consumption 900W Height (with feet): 7.65?

LAB GRUPPEN PLM20000 DSP AMPLIFIER - USED The power amplifier platform of the PLM 20000Q integrates several new developments to maintain reliable, sustained output at unprecedented power levels. The Regulated Switch Mode Power Supply (R.SMPS) is a new universal design that connects to any mains supply in the world. (Operating range is 100 V - 265 V, but new Under Voltage Limiting extends operation down to 65 V with reduced output power.) The design also incorporates power factor correction (PFC) to reduce peak current draw from the mains. Tech Spec:- 5000 W per channel 2.2 – 3.3 ohms 4400 W per channel 4 ohms 2U chassis weighing only 17 kg (37 lbs) Class TD® output stage Universal (70 - 265 V) Regulated Switch Mode Power Supply (R.SMPS )works anywhere in the world Power factor correction (PFC) helps maintain full output during extended power bursts Copper-finned Intercooler with transverse-mounted output devices Comprehensive loudspeaker preset database LoadSmart load verification and SpeakerSafe™ continuousloudspeakerperformance monitoring Dante low-latency digital network included as standard Compatible with Lake LM 26, Dolby® Lake Processor and other legacy Lake devices Primary and secondary network connections Digitally controlled “amplifier gain” adjustable in 0.1 dB steps Digital output attenuation in 0.25 dB steps from -inf to 0 dB Binding post or Neutrik® speakON® output connectors Digitally implemented, zero-overshoot Inter-Sample Voltage Peak Limiting (ISVPL™) adjustable in 0.1 V steps from 17.8 to 194 V Power Average Limiter (PAL) with software-controlled Breaker Emulation Limiter (BEL) prevents mains fuse tripping Under-Voltage Limiting (UVL) enables continued operation with mainsvoltage sags as low as 65 V High-brightness front-panel LCD display Moisture resistant silicone touchpad
