USER MANUAL 8 channel mixer Skytec

Congratulations on the purchase of this SkyTec mixer. Please read this manual carefully prior to using the unit.

Warning:

• Read the manual prior to using the unit.
• Keep the manual for future reference.
• Keep the packaging for safer transport in its original packaging
• For indoor use only.
• Prior to the first use, have the unit checked by a qualified person.
• The unit contains voltage carrying parts. DO NOT open the mixer.
• When you unplug the unit from the mains always pull the plug, never the lead.
• Never plug or unplug the unit with wet hands.
  If the plug and/or mains lead are damaged, they need to be repaired by a qualified technician.
  If the unit is damaged to an extent that you can see internal parts, do not plug the unit into a mains outlet.
• Repairs and lamp replacement has to be carried out by a qualified technician.
• Only connect this unit to an earthed mains outlet of 230Vac / 50Hz and 10-16A.
• Do no place the unit near heat sources.
• Always unplug the unit during a thunderstorm or when it is not in use.
• If the unit has not been used for a longer period of time, condensation can occur inside the housing. Please let the unit reach room temperature prior to use.
• Keep out of the reach of children.
• All channel controls and the master volume control must be set to zero prior to switching the unit on.
• Set the channel slider controls slowly. Fast variation can overload the speakers.
• To prevent clipping of the amplifier do not set the volume level too high.
• Switch the amplifier on at latest and switch it off at first.
• Do not use cleaning sprays for the slider controls. The residues of these spray cause dust deposits in the controls. If a problem occurs, please consult a specialist.

INTRODUCTION

Channels 1-2 (172.558) / 1-4 (172.561) are mono channels. They are fitted with balanced and unbalanced Mic/Line inputs. The 4 other channels are stereo channels. They are convenient for MIDI signals and signals from electronic instruments. The AUX Send function of this mixer is post-fader. The AUX Return function has 2 outputs that can be linked to a MIDI receiver or an electronic instrument. All numbers below in brackets refer to figure 1.

MONO INPUT CHANNELS

Every mono channel is fitted with an XLR microphone input (1) and a balanced 6.3mm line input (2). Phantom power can be switched on at the rear panel (29). The trim circuit features a large range from -10dB to +60dB.

Set the strength of the mic input signal via the trim control (3). Every channel is fitted with a PEAK LED (9). If it flashes or lights up, you have to reduce the signal otherwise the channel will be overloaded. Watch this LED especially if you use very heavy EQ settings (these LEDs show the post EQ signal).

Every mono input channel has its own 3 band EQ. The high button (4) sets the high frequencies ("0" value is 12kHz ), the Mid button (5) the medium frequencies (peak response via the EQ on 2 octaves, "0" value of 2.5kHz ) and the Low button (6) the low frequencies ("0" value is 80Hz ). All three bands have a cut and boost up to 15 dB and a center position of "0".

The AUX Send (7) on both units (172.558 and 172.561) is post-fader. This button controls the signal strength to the AUX terminal. The gain to the master is set via the channel volume button (10).

The channel Pan (8) sets the position of the stereo output. Whatever the position may be, there should be no difference in the volume level.

STEREO INPUT CHANNELS

Every stereo channel has two 6.3mm balanced inputs for a stereo line input signal. As only the left input is connected, this channel will work exactly as a mono channel.

The stereo inputs are designed for any line input signal. Most line sources such as MIDI instruments and FS units have their own output level control. The units without output level control such as CD players have an output level which is within the range of the 172.558 and 175.561. If the channel and master faders are set to the same level, the Vu-meters will display a value between -4 and -7 dB.

The only difference with the mono EQ is that a stereo channel includes no low-cut filter as this equalizer is stereo and not mono.

The AUX Send function on a stereo channel works exactly as on a mono channel. The stereo signal should be bridged to a mono signal.

The only difference with a mono channel is the implementation of a balance/pan button (11). This button determines the balance between the left and right signal that is sent to the right and left master output. If a stereo channel is used in mono mode (only the right input is connected), the balance button operates as a pan control in mono mode.

MASTER SECTION

The AUX Send signal is applied to unbalanced 6.3mm jacks (21). Set the input level of the effect unit to the output level of the mixer. If your effect unit is not fitted with a gain control, you can amplify the signal via the AUX Send button (7) up to 15 dB.

There is an additional stereo input (AUX Return) on your mixer. The level of this input can be set via the AUX Return button (12). This input is permanently affected to the master output. If a connector is plugged into this input, the AUX Return function works with a mono signal. This input allows you to create a 'wet mix'.

The output level of the master section is displayed via a 10 LED bargraph vu-meter (13). Two other LEDs give you an indication about ON/OFF (14) and phantom power ON/OFF (15).

Peaks are shown on the vu-meter around the 0 level. If the vu-meter displays over a longer period of time +10dB for the signal, the master volume and/or the channel volume must be reduced. If this is not sufficient, you can still reduce the gain of that channel and/or the output level of the instrument of effect unit.

The RCA inputs are for connection of a CD player or a turntable. You can now route the signal via the "tape/rec to control room level" push button (17) to the studio monitors or to the master routes via the push button "tape / rec to master" (18). Make sure however that the push button (17) is in the up position otherwise the signal will be input twice.

Connect the mixer to an amplifier via the balanced "stereo out" sockets (22). Use 2 6.3mm mono jacks for this connection. The total output volume is set via the master volume button (19).

The mixer is fitted with a separate headphone output (23). The signal is the same as from the control room output (27). The volume control (16) sends the signal to the headphones and the monitors. The L/R meters are the same as the master output

INSTALLATION

Do not mix up the cable in order to avoid wrong connections. Connect the leads one by one and not all leads on one side first and then all on the other side. In the worst case, you might permanently damage the unit. Figure 2 shows an example of possible connections.

Prior to connecting the mixer, set all controls to "0". You can connect microphone or line units to the mono channels, all kinds of line units to the stereo channels and effect units to the AUX Return. You can also connect Midi instruments to the AUX Return.

If you connect a microphone, make sure that the phantom power is switched OFF. DO NOT use unbalanced units when the phantom power is switched on. Do not short-circuit the 48V circuit of the phantom power to the ground. You might heavily damage the unit.

If you record something on a DAT or ADAT recorder, do not set the maximum level. If your recorder can support a level of 96 dB, record at a maximum level of 86 - 91 dB. The peak level must always be 5 - 10 dB lower than the maximum level of your recorder.

CONNECTIONS

On a balanced in/output, always use balanced equipment. You can use either balanced or unbalanced equipment on an unbalanced in/output. See the drawings below for the equipment that you can use:

If possible, connect the balanced outputs to other balanced units to avoid interference.
