5D Architectural specifications

The amplifier shall be four channel incorporating a digital signal processor (DSP) to provide loudspeaker specific configurations and functions and dedicated protection circuits.
It shall be equipped with Dante network audio and analog signal inputs as well as remote control and monitoring capabilities via Ethernet (OCA/AES70).
User interface shall be front panel Led indicators and via remote control software.
Analog inputs shall be electronically balanced with an input impedance of 15 kOhm.Connector type for the analog audio inputs shall be 3-pin Euroblock 3.5 mm male connectors.
Signal processing shall utilize 48 kHz sampling rate with 24 Bit ADC/ DAC conversion while the latency shall not exceed 1.1 msec.
The output connectors shall be 2 x 4-pin Euroblock 5.08 mm female connectors.
Four GPI lines shall be provided on a 6-pin Euroblock 3.5 mm male connector as digital control lines. The GPIs shall allow either level (Hi/Lo active) or edge (rising/falling) triggering and shall also provide a VCA functionality. In addition a DC-Out with 12 V/50 mA shall be provided.
A FAULT contact shall be provided on a 3-pin Euroblock 3.5 mm male connector to allow a general device error to be remotely indicated.
The amplifier shall incorporate one user definable 8-band equalizer for independent application to each channel allowing parametric filters, notch, hi- and lo- shelve filters as well as asymmetric filters.
A signal delay capability of up to 300 msec (100 m / 328 ft) shall be incorporated for independent application to each channel.
It shall contain a signal generator offering pink noise or sine wave program.
Load monitoring and System check functions shall be included to ascertain the status of the loudspeaker impedance. Load monitoring shall allow impedance monitoring to determine the status of an LF or HF driver in systems with multiple elements, even if these are crossed over passively.
Input monitoring shall be included to allow detection of incoming pilot signals.
A Fallback function shall be available to enable the definition of primary (Regular) and secondary (Fallback) signal paths for analog and network audio input signals with two different modes (Manual or Auto). It shall ensure that any secondary or emergency signal fed to the Fallback inputs is transmitted when required.
An Override function shall be available to allow a dedicated input to be set as a major signal path with highest priority for general messages or emergency services.
An AutoStandby function shall automatically switch the amplifier to Standby mode after a predefined time when the incoming signal level at the individually specified inputs drops below a defined threshold. The function shall be independent of the mute status of the respective channels.
An AutoWakeup function shall automatically repower the amplifier, when an input signal is present and exceeds a defined threshold.
A universal range switched mode power supply shall be incorporated and allow mains range of 100 to 240 V AC, 50 - 60 Hz mains power supply voltages. Mains inrush current limiter, self-resetting overtemperature and overvoltage protection shall be incorporated. Power factor compensation (PFC) shall be incorporated to provide a clean and efficient sinusoidal current draw.
It shall have a temperature-controlled fan for cooling the internal assemblies.
The power amplifier channels shall have output pop-noise suppression, DC offset protection, output HF voltage limitation, output current limitation/protection and self-resetting overtemperature protection. The fan noise emission shall not exceed 42 dB(A).
The output voltage shall be 120 Vpeak. The output power rating shall be 4 x 600 W into 8/4 ohms at a crest factor (CF) of 12 dB, all channels driven.
The S/N ratio (unweighted, RMS) shall be > 108 dBr (analog input) and > 111 dBr (digital input).
The dimensions (H x W x D) shall not exceed 1 RU x 9.5" x 435 mm (1 RU x 9.5" x 17.1") and shall weigh no more than 4.6 kg (10 lb).

The amplifier shall be the 5D by:
