![]() ![]() This card is equipped with a pair of RJ45 sockets, a USB‑B port, a couple of BNCs, and a miniature button associated with a trio of LEDs. The optional digital card is bolted in place on pillars above the motherboard, to which it connects with a ribbon cable. Power comes from an external line-lump which accepts 100-240 V AC via its IEC socket, and delivers ☑6V and +48V to the main unit via a five-pin XLR. Once recognised, all of the unit's facilities are controllable and can be stored/recalled from the app via a graphical mimic of the front panel.Ī quad DIP switch beside the network socket is reserved for 'a future product update'. The process, which is pretty painless, is done via the gain encoders in the relevant configuration mode. DHCP network IP assignment is available, but Neve recommend setting a fixed IP address. The rear panel includes a space for an optional bolt-in card, which adds both Dante and USB interfacing.Ī single RJ45 socket caters for remote-control over Ethernet - up to eight OPXs can be controlled simultaneously from the Mac/Windows control software. While it's possible to use the OPX as a unity-gain summer, via the monitoring output, there are no transformers on the line input to monitor output signal path. There are no insert points between the mic/line/instrument inputs and the digital card. Another D‑sub provides electronically balanced analogue line outs, and a quartet of XLRs accepts an external stereo input to the monitoring and provides the stereo monitoring output. On the rear panel, a pair of AES59 (Tascam) 25-pin D‑subs accept the eight balanced mic inputs (with phantom power), and eight electronically balanced line inputs. With eight versatile inputs and stereo monitoring, a lot of sessions could be handled very comfortably with no more than a 1073OPX and a laptop! Connectivity Naturally, these facilities can all be remote-controlled. ![]() The last button on each channel introduces a 12dB/octave 80Hz high-pass filter. Phantom power only appears on the front and rear mic connectors, of course, and the DI is apparently balanced, with a transformerless class-A buffer amp presenting a 650kΩ input impedance. The gain ranges for the three input modes are +20 to +70 dB for mic, ☒0dB for line, and +30 to +60 dB for DI inputs, and the gain setting is shown on a large, red, seven-segment LED meter.Īn 'FNT' button selects the front panel's combi XLR input instead of the rear-panel connectors and, handily, this accepts mic, balanced line, or instrument inputs. Three illuminated buttons select phantom power, a 25dB pad (for all three input modes), and a low-impedance mic input option, reducing the default 1.3kΩ to 300Ω.Ī button selects the input mode, the current selection indicated by one of three coloured LEDs, and pressing and holding this button for a few seconds inverts the input polarity. On each channel, a familiar red, winged gain knob operates a detented rotary encoder. Differential line-receiving ICs replace the line input transformers of the original design. ![]() #VOLTAGE OUTPUT OF A NEVE 1073 PREAMP DRIVER#The original output driver and big transformer have been replaced with an electronically balanced configuration, which has lowered the overall distortion (from around 0.07 to 0.002 percent) and reduced the power consumption. While the OPX preamps clearly incorporate new technology and look a little different from most 1073s, they share the same heritage, most obviously at the front end, which is balanced with a low-noise version of the Neve Marinair TF10003 mic input transformers, encased in mu-metal cases to ensure the original EIN specification of -125dB has been maintained, and the preamp's maximum output level (+26dBu) remains the same too. ![]() The digital card caters for both Dante and USB connections at up to 192kHz, and enables the 1073OPX to serve as an eight-in, two-out Core Audio/ASIO USB audio interface. The remote-control facilities build on those developed for a version of the 1073 preamps first employed in Neve's Genesys Black console. Perhaps the biggest change is that the preamp gain is now controlled using MDACs (Multiplying Digital to Analogue Convertors), with 1dB increments, to enable exact resetting and accurate alignment of stereo pairs. Neve now offer several variations of the 1073 but the latest, launched to mark its 50th birthday, is like no other: with the eight-channel, rackmounting 1073OPX, Neve have reinvented the 1073 to suit modern DAW-based workflows, and to that end, it boasts remote-controllable preamps, stereo monitoring facilities, and an optional digital interface card. The Neve 1073's alluring sound quality and legendary associations with some of the greatest music ever recorded mean that this preamp has remained consistently popular for many decades. Could this be the perfect partnership between vintage vibe and contemporary convenience? ![]()
