The DATEQ Ace is a small, but versatile, six channel 19-inch mixer. It is highly suitable for use in dancing-schools, conference centres etc. The Ace is equipped with eight line-inputs, and four microphone inputs (channel 1...4) with, for each microphone, a gain-trimmer at the rear, an internal two-band equaliser and phantom-power that can be switched off.

Each microphone channel has a talk-over circuit to improve the speech intelligibility. This circuit, which is triggered by the microphone signal (i.e. it is voice-activated), ensures that this signal overrides all others. The TalkOver circuit of each microphone channel can be enabled or disabled with an internal jumper. The talk-over function can be disabled with the TalkOver switch on the front.

The TalkOver threshold can be adjusted internally.

The Ace has three output-zones. Zone 1 has a dual equaliser, balance and volume-control. This zone is equipped with balanced and unbalanced outputs. Zone 2 only has a volume-control and unbalanced outputs. The volume of the third, optional, output zone can be controlled with an external potentiometer or a control voltage.

Dateq Ace Manual Installation

EN

Installing the Ace

The Ace is designed to be fitted in a 19-inch rack and is just 1 unit high! The cabinet fits in an opening of 445 x 44 x 140mm (W x H x D). See also the dimensioned drawings below.

The 19-inch front is 3mm thick. When installing the mixer, remember to allow sufficient room for the connectors and plugs on the Crew’s rear!

BALANCED

ZONE 1 L/ R

ZONE 1/ 2/ 3

ZONE 3 Volume

Electronically balanced master outputs on XLR connectors for the left and right channels of zone 1. This type of output guarantees perfect signal transmission even if long audio cables are being used.

Unbalanced outputs on cinch connectors. These can be used to connect the Ace to an amplifier or recorder.

This input controls the volume of the additional zone. Between the tip and the shield a potentiometer or an external control voltage can be supplied.

See page 7 for a more detailed explanation.

CHANNEL 6 and 5

Cinch connectors for the stereo line inputs. Each channel has two identical inputs (line 1 and line 2) for CD-players, keyboards, MD-players etc. With the input-selector on the front on of the two inputs can be activated.

CHANNEL 4...1

MAINS/ FUSE

Combined mono mic/ stereo line channel with an electronically balanced microphone input on a XLR-connector and a stereo line input on a cinch connector. When using an unbalanced microphone pin 1 and pin 3 must be connected to the shielding of the cable. Each microphone-input has a gaintrimmer at the connectorboard.

Euro mains-input. The Ace operates at 230V/ 50Hz. Fuse: 5x20mm (small),

315mA slow.

For all audio cinch connectors:

White = Left, Red = Right

Zone volume control

By means of this input the volume of the optional third zone can be attenuated or amplified. The volume control can be connected in two different ways:

Supplying an external voltage

When a positive voltage is supplied between the tip and the shielding of one of the cinch-connectors the volume will be attenuated (for both the left and the right channel). When a negative voltage is supplied the signal will be amplified. The amplification ranges from +14...-80dB. The graph below shows the attenuation as function of the applied voltage:

Connecting a potentiometer

It is also possible to connect a potentiometer between the tip and the shielding to one of the cinch connectors. The signal can only be attenuated. The attenuation ranges from 0...-80dB. A 10kOhm logarithmically potentiometer gives the best results. The next graph shows the attenuation as function of the angle of rotation:

When an adjustable attenuation is not necessary a cinch connector with a short-circuit between the tip and shield must be connected. When the input is left open the volume will be fully attenuated.

Combined microphone/ line channel (1...4)

These channel can be used to connect a microphone or a line source. The channel is equipped with gain-control and input-selector. Each microphone channel has a separate phantom-power supply, a TalkOver circuit and an internal dual equaliser. The microphone inputs have a gaintrimmer at the connectorboard. Each line-channel has the possibility to adjust the input sensitivity by means of an internal resistor.

AIN SETTINGS LINE CHANNELS

The input-sensitivity can be adjusted for each line input. This can be done by replacing an internal resistor. When the cover is opened two conventional zero-ohm resistors can be found, just above the input selector of each channel. See the drawing below. When the resistor values are increased the the input-sensitivity will drop. See the graph below for the resistor-attenuation curve.

QUALISERS

All microphone channels have an internal two-band equaliser. This equaliser is activated when the microphone-input is selected.

To adjust the equaliser settings the cover has to be removed. On the PCB two black timmers can be found for each microphone channel. See the drawing below.

With a small screwdriver the level can be adjusted. As default both trimmers are in centre position

(this means no equalisation). The maximum adjustment is +/- 18dB.

POWER

For each microphone-channel the phantom-power can be switched on,- or off.

To do this the cover has to be removed. On the PCB a jumper can be found with the text phantome

+24V. By placing the jumper on the lower two pins the phantompower is activated. When the jumper is places on the upper two pins the phantompower is disabled.

As a default the phantom power is disabled for all microphones.

VER THRESHOLD

The TalkOver threshold can be adjusted with an internal trimmer. To do this the cover has to be removed. The trimmer is situated at the fourth microphone channel. Below the equaliser timmers an addition trimmer can be found. See the drawing below.

With a small screwdriver the level can be adjusted. By speaking in the microphone the level can be tested.
