JHS Mini A/B Box Pedal
The JHS Mini A/B Box is a passive footswitch designed for simple signal routing. It allows you to switch between two different signal paths or use it as a mute switch.
Funkcijas
- Selects between two 1/4" jacks (A and B).
- Can be used to switch between two amplifiers or two instruments.
- Functions as a tuner isolation switch or a mute switch.
- Compact design for pedalboard integration.
Iestatīšana un darbība
- Connecting Instruments/Amps: Connect your first instrument or amplifier to the 'A' jack and your second to the 'B' jack. The common input/output will connect to your main signal chain.
- Pārslēgšanās: Press the footswitch to toggle between the 'A' and 'B' paths. An LED indicator will show the active path.
- Tuner Isolation: Connect your tuner to one of the outputs (e.g., 'B') and use the footswitch to send your signal to the tuner for silent tuning.
- Izslēgšanas funkcija: By switching to an unused output, the pedal can effectively mute your signal.

Video demonstrācijas
JHS Little Black Amp Box Overview
Video: An influencer demonstrates the JHS Little Black Amp Box, explaining its function as a master volume for an amplifier's effects loop. The video shows the pedal's compact size and how to connect it to an amp's send and return jacks.
Using JHS Black Box for Bedroom Level Practice
Video: A user demonstrates how the JHS Black Box pedal can be used with a high-wattage amplifier (EVH 5150) to achieve desirable tones at lower, bedroom-friendly volumes without needing an attenuator. The video shows the amp's settings and the resulting sound with and without the pedal engaged.
JHS Summing Amp Input Signal Blender
The JHS Summing Amp is a passive signal blender that combines two input signals into a single mono output. This is particularly useful for parallel effects routing.
Funkcijas
- Combines two 1/4" input signals into one mono 1/4" output.
- Ideal for running effects in parallel to maintain clarity and avoid signal degradation.
- Passive design requires no external power.
Iestatīšana un darbība
- Ievadu pievienošana: Connect your two desired signal sources (e.g., two different effects pedals, or two different instruments) to the two input jacks on the Summing Amp.
- Izejas pieslēgšana: Connect the single output jack of the Summing Amp to the next stage in your signal chain (e.g., amplifier input, mixer).
- Parallel Effects: Use the Summing Amp to combine the outputs of two effects pedals that you wish to run in parallel. This can preserve the individual character of each effect.

Vispārējā apkope
- Tīrīšana: Use a soft, dry cloth to clean the exterior of the pedals. Avoid abrasive cleaners or solvents.
- Uzglabāšana: Store the pedals in a dry environment away from extreme temperatures and direct sunlight.
- Savienojumi: Ensure all cables are securely connected to prevent signal loss or intermittent operation.
- Power (Mini A/B Box only): The Mini A/B Box is passive and does not require external power for its primary switching function. The LED indicator, however, requires a standard 9V DC power supply (not included). The Summing Amp is entirely passive and requires no power.
Problēmu novēršana
| Problēma | Iespējamais cēlonis | Risinājums |
|---|---|---|
| No signal output (Mini A/B Box) | Incorrect cable connection; faulty cable; inactive path selected. | Verify all cables are correctly connected. Test with different cables. Ensure the desired path (A or B) is active. |
| LED not lighting up (Mini A/B Box) | No 9V DC power supply connected or faulty power supply. | Connect a standard 9V DC power supply. Test with a different power supply if available. Note: The pedal functions passively even without LED power. |
| Weak or distorted signal (Summing Amp) | Impedance mismatch; faulty cables; excessive input levels. | Ensure proper impedance matching with connected devices. Test cables. Reduce input levels from source devices. |
| Dūņa vai troksnis | Ground loop; faulty cables; interference from other equipment. | Try isolating power supplies. Use high-quality shielded cables. Move pedals away from power transformers or other noisy electronics. |
