Dynacord V600:4 4-Channel 600W Power Amplifier 4Ω / 8Ω / 100V
The Dynacord V600:4 is a compact 1U 4-Channel 600W Power Amplifier with powerTANK flexible load sharing, ecoRAIL low-consumption idle mode, dualCOOL thermal management and support for 4Ω, 8Ω, 70V and 100V operation — a versatile, easy-to-install and energy-efficient power amplifier for commercial background music and announcement installations.
The Dynacord V600:4 is a four-channel 600W Class D power amplifier designed as the recommended go-to solution for consultants, installers and specifiers working on small to mid-sized commercial installation projects. Covering education, hospitality, retail, houses of worship and more, the V600:4 combines best-in-class features with innovative Dynacord technologies in a compact 1U form factor — delivering real professional performance, flexible power allocation and resource-efficient power consumption at an attractive price point.
Quick to install and designed to run trouble-free even under demanding power conditions, the V600:4 is the ideal choice for background music and announcement systems wherever a sturdy, versatile and energy-conscious power amplifier is required.
powerTANK — Flexible Power Allocation Across All Zones
At the heart of the V600:4 is Dynacord's proprietary powerTANK technology — a power reservoir that makes the full 600W of total amplifier power available flexibly across all four channels, rather than fixing a rigid power allocation per channel. With 4 x 150W rated power and up to 300W maximum output per channel via power sharing, the V600:4 can simultaneously serve zones with very different power requirements — for example, driving compact loudspeakers in a small kitchen area alongside larger loudspeakers in an auditorium from the same amplifier, with powerTANK automatically allocating power where it is needed without any manual configuration. Variable Load Drive (VLD) ensures that powerTANK capacity is utilised efficiently, providing consistent power to any channel at any impedance. In conjunction with a DSP matrix such as the Dynacord MXE5 Matrix Mix Engine, the V600:4 can also be specified for larger distributed installations as a distribution amplifier for smaller zones.
ecoRAIL & Auto Power Down for Energy Efficiency
The V600:4's ecoRAIL technology delivers power consumption similar to a regular standby level whilst still producing audio output suitable for background music applications — significantly reducing the energy cost of running a permanent installation compared to a conventional amplifier operating at idle. Auto Power Down (APD) mode reduces power consumption to less than 1W when no signal is present for extended periods, making the V600:4 one of the most energy-efficient amplifiers available in its class.
dualCOOL Thermal Management
The dualCOOL thermal design allows the V600:4 to operate as a convection-cooled amplifier in typical conditions — making it completely silent in normal use — whilst an intelligent multi-speed fan engages automatically in extreme thermal conditions to ensure maximum performance and reliability. This makes the V600:4 suitable for both open rack and close-packed rack installation environments, with forced cooling available from side to rear when spacing between units is not possible.
PFC Power Supply & Comprehensive Protection
The V600:4 is equipped with a Power Factor Correction (PFC) switching power supply and a comprehensive protection suite — including audio limiters, high temperature, DC, HF, short circuit, back-EMF, peak current limiters, inrush current limiters and mains over/under voltage protection — ensuring the amplifier resists complete shutdown situations and performs reliably under all mains conditions. Front-panel signal, limit and fault LEDs per channel alongside a power LED provide clear at-a-glance system status monitoring, and a galvanically isolated READY/FAULT relay output and remote on/standby contact closure provide system integration and monitoring capability.
