INTRODUCTION
LDVIBZ10C – 10-channel Mixer with Compressor
The VIBZ 10 C is a versatile mixer with four balanced microphone inputs
featuring high-quality preamplifiers, a low-cut filter and switchable phantom
power. Two microphone inputs are equipped with inserts for individual signal
processing, two more can alternatively be used as stereo line channels.
For an effective sound adjustment, the VIBZ 10 C has very precise 3-band EQs
with conveniently selected mids; two stereo channels can be adjusted with
2-band EQs. The built-in compressor can be continuously adjusted for effective
dynamics processing.
The master section of the mixer features an effects loop, adjustable monitor
outputs and a headphone jack. The VIBZ 10 C also has inputs and outputs for
recording and playback devices; the input signal can be set on the master or
monitor output and the volume adjusted.
QUICK START GUIDE WITH CABLING EXAMPLE
- Make sure that the mixer and all devices to be connected to the mixer are turned off.
- Connect the devices to the mixer using appropriate cables.
- Adjust the input gain of the channels 1 to 4 and all level controllers channel LEVEL and MAIN MIX to minimum. Place all equalizer controllers in the central position (stop). Adjust the volume controller on the active loudspeaker to minimum. Turn on the +48 V phantom power on the mixer only if you are using a condenser microphone.
- Turn on the devices in the following order: Microphone and keyboard (or other source devices), then the mixer and lastly the active speakers.
- Always adjust the gain control of the channels 1 and 2 or 3/4 and 5/6 so that the peak LED of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED by reducing the input gain (Gain).
- Channels 7/8 and 9/10: Adjust the output level of the keyboard (or other source devices) so that the peak LED above the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED.
- Bring the volume controllers (Fader) of the channels in use and of the sum channel MAIN MIX approximately to the 0 dB mark.
- Now increase the volume of the active speakers for the incoming signal (e.g. speaking, singing, keyboard) to the desired level.
- Fine-tuning can now be achieved by adjusting the volume ratios of the channels and by using the equalizer, compressors and effects device as desired.
NOTE: When turning off the devices, please follow these steps: First, set the volume of the active speakers to minimum and turn them off, then the mixer and connected devices can be switched off.
CONNECTIONS, CONTROLS AND INDICATORS
-
MIC IN CHANNEL 1 – 2 & 3/4 – 5/6
Balanced inputs of the channels 1 and 2, or 3/4 and 5/6 with 3-pin XLR sockets for connecting microphones. Channels 1 and 2 are mono channels, the channels 3/4 and 5/6 can be used as both mono and stereo channels depending on the incoming signal (XLR and jack L IN = Mono / jack L and R IN = Stereo) . A 48 V phantom power supply is available for operating condenser microphones, and it can be switched centrally to the XLR sockets (N° 30). Please set the Gain controller (N 4) to minimum (left stop) before connecting or disconnecting a microphone; and switch on the phantom power only after connecting the microphone, or off before disconnecting. -
LINE IN CHANNEL 1 / 2
Balanced inputs of the mono channels 1 and 2 with 6.3 mm jack socket to connect a source device with a line level. Please set the Gain controller (N
- to minimum (left stop) before connecting or disconnecting jack cables.
-
INSERT CHANNEL 1 / 2
3-pin 6.3 mm jack socket for inserting an external signal processing device (Compressor, Gate, etc.) in the respective mixer channel. A special insert cable is required for the connection (Y-cable, 1 x stereo jack to 2 x mono jack or XLR). The assignment is as follows: TIP = Send, RING = Return, SLEEVE = Masse. -
GAIN CHANNEL 1 – 4
Adjusting the gain of the microphone input from 0 to 50 dB, or the sensitivity of the line input from +15 dBu to -35 dBu. Adjust the Gain controller so that the peak LED of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED by reducing the input gain or input sensitivity. -
LOW CUT CHANNEL 1 – 4
Low cut filter for suppressing low-frequency signals. Especially with voice and singing transmissions, an activated LOW CUT feature (switch in the down position) can reduce disruptive bass frequencies and thus increase speech intelligibility. The cut-off frequency is 95 Hz. -
COMPRESSOR
Sliding compressor controller for channels 1 or 2. Depending on the setting, the signal is more or less compressed, i.e. the dynamics of the signal is restricted (controller to the left stop = compressor is disabled, controller to the right stop = maximum compression). The level loss caused by the increasingly stronger compression is automatically compensated by the compressor unit. The use of the compressor can provide for an improved clarity of a singing voice in the mix. -
EQUALIZER HI CHANNEL 1 – 9/10
Equalizer high band for channels 1 to 9/10 (12 kHz, +/-15 dB). When turned to the left, levels are lowered, when turned to the right, they are raised. In the centre position (resting point), the equalizer is inactive. -
EQUALIZER MID CHANNEL 1 – 5/6
Equalizer mid band for channels 1 to 5/6 (2.5 kHz, +/-15 dB). When turned to the left, levels are lowered, when turned to the right, they are raised. In the centre position (resting point), the equalizer is inactive. -
EQUALIZER LOW CHANNEL 1 – 9/10
Equalizer bass band for channels 1 to 9/10 (80 kHz, +/-15 dB). When turned to the left, levels are lowered, when turned to the right, they are raised. In the centre position (resting point), the equalizer is inactive. -
LEVEL AUX POST CHANNEL 1 – 9/10
Volume controller for adding the signal from channel 1 to 9/10 to an external effects device (Effect Send, Post Fader). Use the line output AUX SEND (N 29) to control the effect and the stereo line input ST RETURN (N 17) for routing the effect signal to the mixer. -
PAN CHANNEL 1 / 2 & BAL CHANNEL 3/4 – 9/10
PAN channel 1 and 2: Using the Panorama controller, position the signal of the corresponding channel in the stereo field of the total signal (Centre position = perception of the signal in the middle of the stereo field). BAL channel 3/4 to 9/10: Use the balance controller to set the relative volume between the left and right part of the connected stereo signal. When only the XLR socket or left socket L (MONO) of the line input is in use, the controller performs the function of a Panorama controller. -
PEAK LED CHANNEL 1 – 9/10
PEAK channel 1-5 / 6: Once the red Peak LED lights up, the corresponding channel is operating at the distortion limit. Adjust the Gain controller (N 4) so that the peak LED of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED by reducing the input gain or input sensitivity. PEAK Channel 7/8 and 9/10: Once the red Peak LED lights up, the corresponding
channel is operating at the distortion limit. Adjust the output level of the source device so that the peak LED of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the peak LED. -
