What are the dimensions for the mounting opening for the TOA YM-4CM?
To fit the electrical box for the TOA YM-4CM in the wall or ceiling, make an opening with the following dimensions:
Width: 46 – 50 mm (1.81 – 1.97 in)
Height: 83.5 mm (3.29 in)
The overall height for the electrical box placement is 90 – 98 mm (3.54 – 3.86 in).
What precautions should I take if a low-voltage circuit and a low-power circuit are housed in the same box for the TOA YM-4CM?
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 are the applicable cables for the TOA YM-4CM and related models?
| Model(s) | Cable Type and Specifications |
|---|---|
| YM-1J, YM-3CF, YM-3CM | Microphone vinyl cable, Cross-sectional area: 0.75 – 2.0 mm² (AWG 18 – 14) |
| 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) |
Are there any special instructions for handling cables during the installation of the TOA YM-4CM?
Yes, please follow these notes when handling cables:
• 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 TOA YM-4CM and other connectors in this series?
Below are the connection diagrams for the different models. The legend for the connections is as follows:
H: Hot
C: Cold
E: Shield
[YM-1J]
• Connection of balanced double pole plug: H (+), C (-), E (Shield)
• Connection of unbalanced single pole plug: H (+), C (-), E (Shield) (-). Short terminals C and E.
[YS-4CF] & [YS-4CM]
These models have four connection points. Wire the corresponding numbered pins to the terminals.
[YM-3CF] & [YM-3CM]
• Terminal 1: E (Shield)
• Terminal 2: H [USA type: – (C)]
• Terminal 3: C [USA type: + (H)]
Is there a warning about using phantom power with any of the TOA YM-4CM series connectors?
Yes, there is a specific note for the YM-1J model. As H, C, and E are shorted when not used (for an unbalanced connection), mixers or amplifiers using phantom power cannot be used with this configuration.
