Following his successful big brother, the 1073/500, the new´73JR is a mic preamp in a single 500 series slot with some added features that will cover all the recording needs for engineers and musicians that don´t find the need to track with eq.
Employing only discrete circuitry and conventional components, the’73 junior is a faithful 3 stage all class A 1073 preamp. Styroflex and tantalum capacitors have been used throughout. No corners were cut.
A useful all discrete class A hi pass filter has been added, essential for recording everything with the exception of probably kick drum and and bass.
The Line mode allows for reamping of prerecorded tracks and it´s perfect for adding some class A color to lifeless recordings.
Умный переключенный DI¼&Rdquo;
Наконец, особое уход был привлечен к обработке мощности, внедряя Интернет +24 В медленного включения регулирования (около 20 секунд, чтобы достичь полного напряжения) ваш пипс на ланч -боксе здоровее и делает 73JR независимым от остальных слотов.
• 80dB Class A Microphone preamplifier, HI-LO selectable minimum input impedance, balanced and floating. High gain positions show a higher impedance, ideal for old ribbon mics.
• 50Db Class A Line preamplifier, bridging input impedance, balanced and floating.
• All discrete Class A Ultra High Impedance J-Fet Direct Input on a high quality Neutrik Jack. The DI circuit is ahead of the Mic Input transformer, so the transformer is ON when in DI mode. DI is automatically switched on when inserting a jack.
• Class A single ended, 2N3055 driven, high headroom output stage.
• PAD: 20dB Mic input attenuation ahead of the input transformer to avoid overloading it.
• HI PASS FILTER: Active all discrete Class A 3rd order Bessel, 80Hz Hi Pass Filter. 18dB/octave slope.
• OUTPUT control to allow overloading of the preamp.
• Internal slow turn-on +24v power supply for lower inrush current, which improves your lunchbox performance.
• Carnhill Input and Output transformers.
• 3 gain stage, genuine modular card construction. All active circuitry is on pluggable cards for easier service.
• Marconi style knobs and vintage style engraved pushbuttons.
• Microphone input impedance: HI, 1200 Ohm minimum, LO, 300 Ohm minimum. Higher gain positions gradually have greater impedances, optimum for lo gain ribbon mics. Input is Carnhill transformer balanced and floating.
• Line input impedance: 10K Ohms bridging, Carnhill transformer balanced and floating.
• DI input impedance: Greater than 2 Megohms, unbalanced.
&Бык;
• Maximum output: Greater than +26dBm into 600 ohms.
• THD: Less than 0.025% at 1 Khz, less than 0.05% at 100Hz.
&Бык;
• Maximum gain: Slightly greater than 80dB
• Noise: Less than -100dBm.
• Power consumption: 88 mA per rail @+-16VDC.
