Frequently Asked Questions - CDM8:4 mkV Citronic

How do I clean the blender jar?

The jar is dishwasher safe (top rack recommended). Alternatively, fill halfway with warm water and a drop of dish soap, then run on pulse for 30 seconds. Rinse thoroughly.

Can I blend hot liquids?

No, hot liquids can create pressure and cause the lid to blow off. Let liquids cool to 60°C before blending.

The blender stops suddenly during use.

This indicates overload protection has activated. Unplug, remove some contents, let the motor cool for 15 minutes, then restart.

What is the maximum capacity?

The jar has a total capacity of 1.5 L. Do not fill above the max line (1.25 L for liquids, 1 L for thick blends).

Are replacement parts available?

Yes, you can purchase replacement jars, blades, and lids from Citronic authorized dealers or our website.

How can I reduce noise?

Place the blender on a non-slip mat to dampen vibration. Using lower speeds also reduces noise.

Is the blender suitable for crushing ice?

Yes, use the pulse function on speed setting 3 or 4. Do not overfill with ice; use max 1 cup at a time.

What does the pulse function do?

Pulse gives short bursts of high speed for precise control, ideal for chopping or mixing without over-processing.

The blade seems loose. Is that normal?

A slight movement is normal for safety. If the blade wobbles excessively, stop use and contact customer service.

How long is the warranty?

Citronic offers a 2-year limited warranty covering manufacturing defects. Register your product online to activate.

Operation:

- Check mains for correct voltage as indicated near to the IEC mains inlet on the rear panel.

- Connect to mains supply using the IEC cable provided.

- Connect the Main unbalanced RCA and/or balanced XLR outputs to the main PA and ensure that the volume levels are turned down to avoid damage.

- Connect the BOOTH outputs to powered booth monitors or separate PA zone.

- Connect any turntables to the RCA PHONO inputs on ch.1 and ch.2.

• Earth turntables to the case grounding point on the rear panel

- Connect CD players or other line output sources to the CD inputs.

- Connect CD, CD+G, laptop, TV decoder, DVD or MP3 players to LINE inputs.

- Connect DJ mic and Vocal mics 1 + 2 to the top panel jack/XLR combo sockets

• If required, connect personal MP3 player to top panel 3.5mm input

- Connect headphones to the HEADPHONE jack

- With MASTER LEVEL down, switch the power on.

- Ensure microphone levels are turned down

• Gradually increase MASTER LEVEL and channel levels to check input signals.

- Be aware that the CROSSFADER also operates across assigned channels - this can be bypassed by pressing DEFEAT.

- To use crossfader, select channels using the ASSIGN levers, ensure DEFEAT is off and the crossfader will then seamlessly blend between these 2 channels.

• Gradually increase microphone channel levels to check microphone signals.

• Monitor each stereo channel via headphones selecting using the CUE switches

- Whilst a channel is on CUE, adjust the GAIN so that LED meters show a full signal without showing "in the red" (overload)

- Adjust Hi, Mid and Lo EQ settings to the desired tonal effect

- When using the DJ mic, push the ON AIR switch and if required, push MANUAL OVERRIDE to drop the music level by a fixed amount whilst talking.

- Adjust Hi and Lo EQ and DJ MIC level settings to suit.

- For singers and karaoke, increase the levels of Vocal mics 1 + 2 and adjust Hi and Lo EQ settings to suit.

- For each vocal mic, adjust DELAY level to the desired amount, variation in the time between delay repeats can be adjusted via the TIME rotary.

- Should a different effect (eg. Reverb, compression, DSP) be required, connecting SEND on the rear panel to an external processor's input and the processor's output(s) to the rear panel RETURNS will serve as an effects loop, overriding the internal delay effect. The DELAY controls will now act as an external effects mix.

- When not being used, turn down the Vocal mic levels to avoid unwanted noise.

Troubleshooting

NO OUTPUT -

Check mains power is on

Check leads and connections

Check MASTER LEVEL and mic or channel fader is turned up

Check CROSSFADER by trying the DEFEAT switch

DISTORTED OUTPUT -

Check line input isn't connected to PHONO

Check channel and MASTER faders are not too high

Check volume control of amplifier, active speakers or recording equipment

MICROPHONE FEEDBACK

Eliminate "line-of-sight" between mic(s) and speakers

Check DELAY is not set too high

Adjust Hi or Lo EQ and/or level controls

MICROPHONE OUTPUT

No output – check if mic switched off

No output – check if phantom power source is required

Low output – ensure mic is not switched to "pad" or "Hi Z"

Quiet vocals – ask singer to sing closer to mic.

DELAY EFFECT

Metallic effect but no delay – increase TIME control to produce more natural echo

No delay effect – increase DELAY controls, check nothing is plugged into RETURNS

TOO QUIET -

Check turntable is not connected to line input

Check channel and MASTER faders are not too low

Check for volume control on sound source
