Frequently Asked Questions - V-400 Valcom

How do I connect the V-400 microphone to my Valcom paging system?

Connect the V-400 to a Valcom V-9939A microphone adapter using the provided 4-conductor shielded cable. Wire color coding: red (positive), black (negative), white, green, and shield (strap shield to positive lead). Refer to Figure 1 in the manual for terminal layout.

What is the difference between High Z and Low Z output?

The V-400 has a switch for selecting High Z (high impedance) or Low Z (low impedance, 400 ohms) output. Use Low Z for balanced connections typical in professional audio. High Z may be used with older or unbalanced inputs. Select the appropriate position for your system.

How do I use the lift switch on the V-400?

The lift switch on the bottom of the microphone enables or disables the push-to-talk function. When set to 'Enabled', the microphone will only transmit when the push bar is pressed. When 'Disabled', the microphone remains active continuously. This allows for hands-free operation if desired.

Does the V-400 require phantom power?

No, the V-400 is a dynamic microphone and does not require phantom power. It operates passively without external power. The power terminals on the V-9939A adapter are for other purposes, not for the microphone itself.

What is the frequency response of the V-400?

The frequency response is 50 Hz to 12 kHz. This range is suitable for voice reproduction in paging and public address applications, providing clear and natural speech.

Why is there no sound from the microphone?

First, ensure the push-to-talk bar is pressed (if lift switch is enabled). Check that the lift switch is in the correct position. Verify all cable connections are secure and correctly wired (see Figure 1). Test with a known working system. If still no sound, contact Valcom Technical Support at [phone], option 1.

Can I use the V-400 with non-Valcom equipment?

The V-400 is designed for Valcom paging systems and is optimized for use with the V-9939A adapter. While it may work with other low-impedance microphone inputs, performance is not guaranteed. For best results, use with Valcom equipment.

What is the warranty on the V-400?

Valcom provides a one-year limited warranty from the date of shipment, covering defects in materials and workmanship under normal use. It does not cover damage from misuse, alteration, or unauthorized repair. Contact Valcom for warranty claims.

How should I clean the V-400 microphone?

Clean the exterior with a soft, dry cloth. Avoid using liquids or abrasive cleaners. Do not expose the microphone to moisture. The dynamic element is robust but keep the grille free from dust. For deep cleaning, consult Valcom.

Where can I get my V-400 repaired?

The V-400 is not field repairable. If repair is needed, send the unit to Valcom, Inc. at 5614 Hollins Road, Roanoke, VA 24019-5056. Attach a tag with your company name, contact person, and problem description. Call [phone] for a return authorization if required.
