Operation

Connection

Your new DELTA-50 desktop PA unit may arrive with you with the internal battery charged. Before connecting the 12Vdc

adaptor to the mains, switch the unit on and see if the power LED lights. If not, you will need to charge the battery

before using away from a mains supply (see "Charging the battery" below)

Connect the QR-series portable PA unit to the mains using the fig.8 lead supplied or to a car 12Vdc outlet with the

supplied cigar lighter lead. You may otherwise opt to use the internal battery if charged.

Power Up

Turn VOLUME, ECHO and MIC VOLUME controls down (anti-clockwise) and turn the POWER switch on (the power LED

should light). BASS and TREBLE controls should remain pointing vertically (12-o-clock position) – these can be altered

later to give the overall appropriate tone shape. Your DELTA-50 desktop PA unit should now be ready to operate.

VHF Handheld Microphones

Insert the supplied 9V batteries into the handheld microphones by carefully unscrewing the base of each and connecting

the "+" and "-" terminals of the battery to the corresponding clips inside the mic body.

Take care to observe the correct polarity when installing the batteries.

With the VHF VOL control turned down, press the VHF ON/OFF button on the DELTA-50 so that the VHF POWER LED

lights.

Switch on each wireless mic in turn – the RF LEDs on the DELTA-50 unit should light as a result

If the LED on the handset does not light or stays on dimly lit, change the battery

Gradually increase VHF VOL control, testing each microphone in turn for output through the speaker.

Take care not to incur "feedback" (howling or screeching sound through the speaker) by keeping the microphone a

"hear"

sensible distance from the speaker and pointing away from the speaker so that it doesn't

the speaker output.

Turning the ECHO control clockwise introduces the echo effect for singing and special effects.

A DELAY rotary control changes the delay time of this echo effect.

The CONTOUR control varies the overall EQ shape of all the microphones

Rotating this control alters the microphones' tone from mid-focused to bass + treble enhanced.

When not in use, switch the wireless microphones off. Remove batteries if not being used for long periods of time.

External Inputs

In addition to the unit's own VHF microphones, 6.3mm jack inputs are provided to connect external microphones, which

are both governed by the MIC VOLUME control.

Mic 1 input can also serve as an input for an electric or electro-acoustic guitar.

A VCV switch activates the Voice Controlled Volume feature.

This function gives priority to microphones over playback, so that announcements are more easily heard

When the VCV is on, any sound through the microphones will cause the music playback to "duck" (drop in volume)

The music volume is restored after there is no sound through the microphone (after a short, preset period of time)

Also, an AUX twin RCA input is provided for line input sources such as CD player or personal audio player.

To use these inputs, select the AUX input mode using the media player MODE button

The AUX input is governed by the VOLUME control at the top of the panel and volume settings in the media player

Adjacent to this twin RCA input is a twin RCA line output carrying the overall main mix.

This can be used to connect onto other sound systems or for external recording.
