BUTTONS ON THE FRONT OF THE AMPLIFIER

CONNECTORS ON THE BACK OF THE AMPLIFIER

FRONT PANEL FUNCTIONS

DISPLAY During normal operation the top line of the display shows the selected source, and the bottom line shows the volume setting.
When a digital input is selected, the format received is also displayed (PCM, MQA or DSD).
It is possible to change the source with the rotating knob and/or the up/down buttons when navigation mode is activated. When changing settings (see “MENU FUNCTIONS” page 7), the display will show the setting being changed.

2 STANDBY

Press the standby button 2 to place the amplifier in standby mode, or to switch on the amplifier from
standby mode. When the amplifier is in standby mode, the only light showing on the amplifier will be a dim LED light in the lower left corner. When you switch on the amplifier, the outputs will be muted, and a line will illuminate at the bottom of the displays, starting in the lower left corner.
During the start-up cycle, the circuits of the amp will stabilize, and any power amp(s) connected to the pre outs will have some time to stabilize. When using trig- ger cables between the amplifier and power amp(s), the power amp(s) will be switched on and off together with the amplifier.

3 MUTE / REMOTE CONTROL PAIRING BUTTON

The mute button has multiple functions. When you press this button briefly, it will mute the speaker outputs of the amplifier, and also the pre outs with the standard configuration (see “MENU FUNCTIONS” page 7). The display will show ”Mute” instead of the volume setting.
If you are using an Apple remote, you can pair the am- plifier with one specific remote. In order to pair your remote control with the amplifier, press and hold the front panel mute button 3 for more than one second. When the amplifier is ready to pair, the display will flash slowly. To pair, press a button on your remote control facing it toward the amplifier. The display will show ”Paired”. Press the front panel mute button 3 again briefly to go back to normal operation.
You can remove the pairing, so that the amp will stop responding to the remote again, by pressing the front panel mute button for more than five seconds. When the five seconds have passed, the displays will flash fast. Press a button on the remote, to complete the procedure. The display will show ”Unpaired”. Press the front panel mute button 3 again briefly to go back to normal operation.

Note: Settings, including remote control pairing, are stored when your Aavik device is switched to standby. So remember to switch your device to standby, before removing power.

The navigation button lets you select the desired source. Pressing the navigation button 4 briefly will activate input selection. The display will flash, while still showing the selected input. Turning the volume control knob 5 either clockwise or counter-clock- wise, or pressing the up/down buttons a / b lets you select the desired source. Press the navigation button again to deactivate input selection mode.
The navigation button is also used for accessing the menu. See ”MENU FUNCTIONS” page 7.

5 VOLUME CONTROL (ROTATING KNOB)

SPEAKER TERMINALS

The amplifier accepts speaker cables terminated with spade connectors and 4 mm banana plugs.
To connect speaker wires terminated with spades, loosen the isolation knob and insert the spade be- tween the isolator and terminal. Tighten the isolation knob to secure the spade.
To connect speaker wires terminated with banana plugs, insert the banana plug into the center hole of the terminal.

7 PRE OUT

The amplifier is equipped with a set of pre out (pre- amplifier output) connections. They can be used for an active sub-woofer, a separate power amplifier or a headphone amplifier.

For some uses, such as in combination with an headphone amplifier, you may need to mute the speaker outputs, but not the pre outs. This can be achieved by changing the “Pre Out Mute” setting. See “MENU FUNCTIONS” for guidance.

8 LINE INPUTS

The amplifier is equipped with five single-ended, RCA line inputs.
The gain of the line inputs can be changed to equalize the volume of different signal sources. The range is between 5 and 15 dB for input 1-4, and between 1 and 11 dB for input 5. The default gain for all inputs is 9dB. Please see “MENU FUNCTIONS” for guidance.

9 BNC DIGITAL INPUTS
