What are the mounting opening dimensions for the TOA YM-4CF electrical box?
To fit the electrical box for your TOA YM-4CF in the wall or ceiling, make an opening with the following dimensions:
Width: 46 – 50 mm (1.81 – 1.97 in)
Height: 90 – 98 mm (3.54 – 3.86 in)
The vertical distance between the mounting holes is 83.5 mm (3.29 in).
What should I do if a low-voltage and a low-power circuit are housed in the same box for my TOA YM-4CF?
When a low-voltage circuit and a low-power circuit are housed in the same box, you must provide a partition to isolate them from each other.
What cables are applicable for use with the TOA YM-4CF?
| YS-4CF, YS-4CM | 600 V vinyl-insulated cable or equivalent, Diameter: 0.8 – 1.6 mm (AWG 20 – 14) or Cross-sectional area: 0.9 – 2.0 mm² (AWG 17 – 14) |
| YM-1J, YM-3CF, YM-3CM | Microphone vinyl cable, Cross-sectional area: 0.75 – 2.0 mm² (AWG 18 – 14) |
Are there any special instructions for handling cables when installing the TOA YM-4CF?
Yes, please follow these notes when handling cables for your TOA YM-4CF:
• For cables with a sectional area of under 0.75 mm², fold back their cores to increase the sectional area before connection.
• If a thick cable is used, the circuit board can be damaged when mounting the connector in an electrical box. Take care that excessive force is not applied to the circuit board when mounting.
How do I wire the connections for the TOA YM-4CF?
The TOA YM-4CF (model YS-4CF in the manual) is a 4-pin connector. The wiring diagram shows a direct connection from each of the numbered pins (1, 2, 3, 4) on the connector front to the corresponding numbered terminals (①, ②, ③, ④) on the back.
What do the H, C, and E labels represent in the TOA YM-4CF connection diagrams?
The labels in the connection diagrams correspond to the following signals:
H: Hot
C: Cold
E: Shield
Can I use mixers or amplifiers with phantom power with the TOA YM-4CF and related connectors?
For certain connector types, such as the YM-1J, the Hot (H), Cold (C), and Shield (E) terminals are shorted when not in use. Because of this, mixers or amplifiers that use phantom power cannot be used with those specific models.
