Frequently Asked Questions - Receive 2 Joranalogue

What is the gain range of the Receive 2?

The gain range is from unity (0 dB) up to +40 dB per channel, adjustable via the gain knobs. For +4 dBu balanced signals, set gain around 25% (+10 dB) to reach 10 Vpp. For -10 dBV consumer signals, use about 75% (+30 dB). Passive sources like dynamic microphones may require the full +40 dB.

Can I use balanced inputs with the Receive 2?

Yes, the external inputs accept both balanced and single-ended signals via XLR or 6.35 mm jack connectors. The built-in balanced receivers provide excellent interference rejection, similar to a transformer.

What is the maximum input level?

The module can handle a wide range of signal levels. The gain is adjustable, and the LED meters show output levels up to +6 dB relative to 10 Vpp (Eurorack nominal). Clipping occurs shortly beyond +6 dB, so avoid excessive gain.

How do I connect external instruments like a guitar or microphone?

Connect your instrument using a standard XLR or 6.35 mm jack cable to either of the two input sockets. Adjust the gain knob to achieve a suitable level, monitoring the LED meter. For guitars, start with higher gain (~75%). For dynamic microphones, max gain may be needed.

What does the mix output do?

The mix output provides a sum of both input channels, attenuated by 6 dB to prevent clipping. This allows you to blend two external sources into a single Eurorack signal without needing an external mixer.

How do I read the LED meters?

The peak-responding LED bar meters display output level from -18 dB to +6 dB. 0 dB corresponds to 10 Vpp, the nominal Eurorack level. Since Eurorack headroom is limited, +6 dB is near clipping. Aim for occasional peaks around 0 dB.

My module picks up hum or interference. What should I check?

Ensure your Eurorack case is properly earth-connected. The Receive 2 has separate signal and chassis ground planes. If issues persist, try shorting the ground planes via the solder bridge on the rear of the PCB (marked 'ground short'). Also check cable quality and avoid ground loops.

What are the power requirements?

The module draws +12 V: 35 mA and -12 V: 35 mA. It has reverse polarity protection via a MOSFET. Always use a standard Eurorack power cable and ensure your power supply can deliver sufficient current.

How should I clean the module?

Use a dry, soft, lint-free cloth to gently wipe the front panel and connectors. Do not use water, solvents, or abrasive cleaners. Avoid moisture entering the module.

What if my module is not working correctly?

First, check all power connections and verify your Eurorack power supply is functioning. If the issue persists, contact your dealer or [e-mail]. Include your serial number (found on the product card or module rear). Do not attempt to repair the module yourself.

USER MANUAL Receive 2 Joranalogue

While modular synthesisers are most often used as stand-alone instruments, they also present exciting opportunities for processing external signals. Anything from an electric guitar to an effects send on a studio mixing desk can benefit from the unique sonic capabilities of even a modest Eurorack system.

However, patching in an external source usually requires an adapter cable and plenty of clean gain to bring the signal to Eurorack level. If the signal source is balanced, a balanced input is required as well to provide the best possible interference rejection.

Receive 2 (or RX2 for short) provides a convenient all-in-one solution. It offers two universal external inputs, which accept both balanced or single-ended signals via XLR or 6.35 mm jack connectors.

The circuit incorporates low-impedance design practices, RF filtering and premium balanced receivers to provide transformer-like interconnect performance in a compact and affordable module. And thanks to the electrostatic discharge (ESD) protection, it's rugged enough to survive the rigours of performing on the road.

The very clean integrated pre-amps feature variable gain, ranging from unity to +40 dB on each channel. As a result, Receive 2 can handle just about any signal source you may encounter, including electric instruments, piezoelectric pickups and many dynamic microphones.

Adjusting the gains is a breeze thanks to the dual peak-responding LED meters. A mix output is included as well, so external signals can be easily mixed directly in the module.

CONTENTS

In the Receive 2 box, you'll find:

• Product card, stating serial number and production batch.
  ■ 16-to-10-pin Eurorack power cable.
• Mounting hardware: two black M3 x 6 mm hex screws, two black nylon washers and a hex key.
• And finally, the module itself, in a protective cotton bag.

If any of these items are missing, please contact your dealer or [e-mail].

CONTROLS & CONNECTIONS

1 LED METERS

The peak-responding LED bar meters give a visual indication of the output levels on the 3.5 mm sockets. The scale ranges from -18 to +6 dB, with 0 dB corresponding to the 10 V_pp nominal Eurorack level. Be aware that since Eurorack has limited headroom, +6 dB is very close to clipping.

2 GAIN KNOBS

Use these knobs to adjust the input gain for each channel, from 0 (unity) to +40 dB. With +4 dBu balanced 'professional' input signals, they will typically be set at about 25% (+10 dB) to reach 10 Vpp on the main output sockets. For -10 dBV 'consumer' single-ended input signals, you can expect about 75% (+30 dB) to be the ideal amount of gain. Passive sources such as dynamic microphones may require the maximum gain of +40 dB.

3 MAIN OUTPUTS

These are the main Eurorack outputs. Connect them to the modules you'd like to process the external signal(s) through.

4 MIX OUTPUT

Both input signals are also mixed together internally, and the result is available from this output socket. The signals are attenuated by 6 dB before mixing to avoid clipping.

5 EXTERNAL INPUTS

Connect your external signals here. Just about any signal source may be connected: balanced or single-ended, via XLR or 6.35 mm jack connectors.

Note that the inputs are DC-coupled, so any DC offset that may be present is retained. This makes it possible to receive external CV signals, although DC accuracy may not be sufficient to process pitch CV.

Receive 2 features separate signal and chassis ground planes, joined together at the front panel. This helps to avoid ground currents running through the circuitry and causing audible interference, provided the module is installed in a Eurorack enclosure which is properly earth-connected at its chassis.

In sub-optimal installations, shorting together the ground planes on the rear of the circuit board at the 'ground short' solder bridge point may improve performance.
