Frequently Asked Questions - VCC Grimm Audio

How do I connect the VCC to my audio system?

Use balanced XLR cables for best performance. Connect analog inputs from your source and analog outputs to your amplifier or speakers. For digital connections, use AES/EBU or S/PDIF cables as needed.

What is the correct power-up sequence?

Turn on the VCC after all source and amplifier components are powered on. This prevents any transient noise. Power off in reverse order.

Can I use the VCC with unbalanced equipment?

Yes, the VCC has both XLR (balanced) and RCA (unbalanced) connectors. Use appropriate cables and set the input/output configuration accordingly.

How do I clean the VCC?

Use a dry, lint-free cloth to wipe the front panel and enclosure. Avoid liquids, solvents, or abrasive materials to prevent damage.

What does the OLED display show?

The display shows current input selection, sample rate, output level, and system status. It can be dimmed using the remote or front panel.

Is the VCC compatible with 240V mains?

Yes, the VCC operates on 100-240 V AC, 50/60 Hz. It automatically adjusts to the local mains voltage.

Why is there no sound from the outputs?

Check that the VCC is powered on, the correct input is selected, and all cables are securely connected. Verify that the output level is not muted or set to zero.

How do I reset the VCC to factory settings?

Press and hold the 'Menu' button for 5 seconds while powering on the unit. The display will show 'Factory Reset'. Confirm using the knob.

Introduction

Thank you for choosing the Grimm Audio VCC Video to Word Clock converter. The VCC was designed to be directly attached to a word clock BNC input, effectively turning it into a video sync input. The VCC is therefore the ideal complementary product for use with our CC1 master clock when audio needs to slave to video and a word clock reference is not available. Of course the VCC can also be used with any other device that lacks a video sync input but can slave to word clock. Note that the VCC does not have jitter attenuation because the CC1 takes care of that. When using the VCC with a device other than the CC1, make sure that it too has good jitter suppression.

1. Installing

Signal connections

The VCC can be mounted directly on the BNC connector of the receiving or transmitting device, as shown in the picture below. Alternatively, 75Ohm BNC cables can be used on both sides of the VCC.

Power supply

The power supply of the VCC is provided by the wall adaptor unit that is linked to the VCC. It was decided to use a fixed connection between the wall adaptor and VCC because the standard supply connections showed unreliable performance on the road. A well functioning VCC can be vital in your facilities system, so we sacrificed the convenience of a detachable supply.

2. Operation

Lock indication

The VCC locks to PAL, NTSC and SECAM video signals. Usually a black burst signal is used for reference, but the VCC will lock to any type of video content. The little white LED that shines through the dot hole of the 'i' in the VCC | Grimm logo functions as power and lock indication. It will blink in case no lock is possible and it will light continuously when the VCC is locked to the video signal.

Output sample rate

VCC's are shipped off factory with the output sample rate set to 48 kHz. If your application demands a 44.1 kHz sample rate, this needs to be changed inside the box. First make sure the power supply is removed from the power outlet. Then unfasten the four Phillips screws in the corners of the lid. Remove the lid and locate the jumper in the interior. When the jumper is open the VCC provides 48 kHz word clock, when it is closed the unit offers a 44.1 kHz word clock. In the pictures below the two settings are illustrated. After setting the jumper in its preferred position, remount the lid (noting the correct position of the dot hole) and lock it with the Phillips screws.
