Operation

Your new DELTA-200 portable PA unit may arrive with you with the internal battery charged. Before connecting the unit to the mains supply, 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 DELTA-200 to the mains supply (38) using the supplied IEC power lead or alternatively, by connecting a battery or power adaptor to the 12-15Vdc power input (39). Observe the LEDs (40) adjacent to the DC power input.

The POWER LED shows green when power is on and red when the battery is low.

Power Up

Turn all VOLUME controls down or off (8, 14 20, 25, 31, 37) and turn the POWER switch (41) on

All BASS, TREBLE and EQ controls (7, 8, 10, 11, 12, 27, 28, 34, 35) should remain pointing vertically (12-o-clock position)

These can be altered later to adjust the tone character of each input.

Your DELTA-200 portable PA unit should now be ready to operate.

Instrument Input Channels

The DELTA-200 has 2 dedicated input channels for electric instruments, such as electric or electro-acoustic guitars, basses, mandolins or ukuleles, which have magnetic or piezo pickups. Note: these are more sensitive than line inputs.

Connection from the instrument is via 6.3mm jack (9). Once connected, ensure that the volume is turned up on the instrument and gradually increase the channel VOLUME for the relevant input (14), checking for output to the speaker.

Each instrument channel has 3-band EQ for tone shaping.

The HI control (10) adjusts the level of high frequency content (treble) for the relevant instrument input.

The MID control (11) adjusts the level of mid frequency content (middle) for the relevant instrument input.

The LOW control (12) adjusts the level of low frequency content (bass) for the relevant instrument input.

Turning any of these controls anti-clockwise will cut these frequencies or clockwise will boost these frequencies.

The 12 o’clock position is the neutral, unaffected setting.

Both instrument inputs are also served by an EFFECT level control.

Turning the EFFECT (13) control clockwise introduces more of the echo level. MIN = no echo and MAX = full echo.

For further information, see the “Delay Effect” section further along in this document.

UHF Handheld Microphones

Insert the supplied AA batteries into the handheld microphones by carefully unscrewing the base of each and aligning the “+” and “-” ends of each cell as imprinted in the battery compartment. Take care to observe the correct polarity.

On the rear panel, turn the UHF A and UHF B controls (25, 31) clockwise to switch power on to the receivers.

The “ON” LED for each UHF receiver should now be lit (26, 30) – the “RF” LEDs are only lit when the handheld mic is on.

Turn up each of these controls part way for checking each UHF microphone.

Switch on each handheld mic by sliding up the switch fully (halfway is “muted”) – the “RF” LEDs (26, 30) for UHF A and B should light in turn. If the LED on the handset does not light or stays on dimly lit, change the batteries and try again.

Gradually increase UHF A and UHF B controls, 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 sensible distance from the speaker and pointing away from the speaker so that it doesn’t “hear” the speaker output.

Both UHF A and B microphones are served by a pair of EQ controls and an EFFECT level control.

The HI-MID control (27) adjusts the level of high and mid frequency content (treble + middle) for both microphones.

The LOW control (28) adjusts the level of low frequency content (bass) for both microphones.

The 12 o’clock position is the neutral, unaffected setting. Clockwise boosts the EQ. Anticlockwise cuts the EQ.

The EFFECT level control adjusts the amount of UHF mics signal feed to the delay section, from no effect up to full effect.

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

Additional Inputs

In addition to the unit’s own wireless UHF microphones, a MIC/LINE IN combo XLR/jack input (32) is provided to connect an external microphone or line input. A MIC/LINE switch (33) sets the input sensitivity to suit which type of input is used.

On the top panel, a VCV switch (16) activates the Voice Controlled Volume feature when pressed in.

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

When the VCV is on, any sound through the UHF microphones or Mic/Line input will cause the playback to be muted.

The music volume is restored after there is no sound through the UHF or mic/line input after a short time.

Alongside the VCV switch is a 3.5mm AUX stereo jack input (15), which may be used to connect a smart phone or mp3 player for playback of audio tracks. This input is played through the media player, selected via the MODE button.

A further input is provided for connecting an electronic KEYBOARD or DRUMKIT via 6.3mm jack (18). This can instead be used simply as a LINE input (e.g. CD, radio tuner, mp3 player) via the L+R RCA sockets (17) or 3.5mm jack (19).

This input is shared by all three input types and is governed by a single VOLUME control (20).

Alongside the KEYBOARD / DRUMKIT / LINE VOLUME control is an OUT/REC 3.5mm jack line output (21), which can be used to connect onto a recorder or further amplifier, carrying a mix of all inputs heard through the DELTA-200 speaker.

Delay Effect

The DELTA-200 is equipped with an internal digital delay effect unit for microphones and instrument inputs to share.

There are separate EFFECT level controls on each input channel that control how much signal is fed to the delay section.

The overall delay effect level to the output is determined by the EFF LEVEL control (24). MIN = off, MAX = full output.

The DELAY control (22) changes the time between echo repeats. MIN = short slap-back echo, MAX = long delay.

The REPEAT control (23) varies the number of regenerated repeats. MIN = single repeat, MAX = many fading repeats.

Internal Media Player

The DELTA-200 onboard media player can play audio from USB/SD media, FM radio, AUX input or a Bluetooth device.

Any audio source from the media player is governed by the media player VOLUME control (8).

The media player also has dedicated TREBLE (6) and BASS (7) EQ controls to adjust the tone character.

The 12 o’clock position is the neutral, unaffected setting.

Turn the TREBLE control anticlockwise to cut high frequencies or clockwise to boost high frequencies.

Turn the BASS control anticlockwise to cut low frequencies or clockwise to boost low frequencies.

The backlit LCD display (4) has a row of controls beneath it for control of playback sources (2)

Once fully scanned, the stored stations can be accessed via the and buttons.

To connect a smart phone or other Bluetooth device to the DELTA-200 media player, press the MODE button repeatedly until the display shows “BT” then “PHONE”. Open the Bluetooth menu on your device and search for “PA SYSTEM TSR12”. Pair with this ID and connect in order to be able to play audio from the Bluetooth device to the DELTA-200.

During Bluetooth playback, pressing the and buttons will navigate tracks in the folder on the sending device.

Pressing the will pause or play the current track.

The EQ button can also apply the POP, ROCK or CLASSIC tonal profile or select “EQ OFF” for the unaffected option.

To play audio from the 3.5mm AUX IN jack, press the MODE button repeatedly until the display shows “AUX IN”

It is recommended to turn down all volume controls before powering down to avoid loud pops through the speaker.

Audio Recorder

To record the full mix of inputs that can be heard through the DELTA-200 speaker, insert a separate FAT32 formatted USB pen drive into the USB REC port (5) and the recording LED will light to show that it is ready to record.

Press the “REC” button to start recording and the recording LED will flash whilst audio is recorded to the pen drive in standard .wav audio format. Press the “REC button again to stop recording and the recorded track will be stored as a .wav audio file named by numerical order (e.g. 001.wav)

Remote Control

In addition to the panel controls, an infra-red remote control is provided for the USB/SD player which adds some further functions to allow greater control over the media player.

To operate, remove the clear plastic tab from the remote to activate the battery.

Charging The Internal Battery

When not in use but connected to the mains, if the POWER switch is in the off position, the internal battery will be re-charged from the mains supply. This can be observed by the green battery status LEDs being lit.

Note: it is recommended to store the PA unit at an ambient temperature and not with the battery fully discharged.
