FRONT PANEL FUNCTIONS

1DISPLAY

During normal operation the left side of the display

shows the selected source, and the right side shows

the volume setting.

It is possible to change the source with the up/down but-

tons. When changing settings (see “MENU FUNCTIONS”

page 8), the display will show the setting being changed.

In the event of an error, a line at the bottom of the

display will show error messages. The possible errors

are DC, over current and high temperature. The errors

are explained in the following section.

OVER CURRENT

If the amp displays “Error: Short Right” or “Error: Short

Left”, too much current is running through the output

stage. This usually occurs because of a short circuit

in the speaker wiring. When the error is detected, the

speaker output(s) will be switched off, and you have

to switch the amplifier off and back on, to re-enable

normal operation. Before you switch the amp back

on, make sure that there are no wiring errors. The

error could be strands of wire from the speaker cable

touching each other or the metalwork of the amplifier.

If the error is displayed again after power cycling the

amplifier, and even with speakers disconnected, the

amplifier has been damaged, and will need servicing.

If the amp displays “Error: DC Right” or “Error: DC Left”,

DC is present on the output(s) of the amplifier. When

this occurs, the speaker output(s) are disabled to

protect the speakers. If music is playing, the sound

will be distorted and low in level. The DC could come

from the preamp or a signal source. Try switching

the amplifier off and back on. If the DC error is still

present, try switching the amplifier off, disconnect

the input cable(s), and switch the amp back on. If the

DC error persists, with input cables disconnected, the

error is in the power amplifier. Otherwise the error is in

the preamplifier or the signal source.

HIGH TEMPERATURE

If the amp displays “Error: Temp High”, the tempera-

ture inside the amplifier is reaching critical levels. This

can occur if the ambient temperature is too high and/

or the amplifier has been delivering large amounts of

power into low impedance speakers. When the error

is first shown, it is only a warning. If the temperature

drops again, the message will clear. If the temperature

continues to rise however, the amplifier will switch

off. In that case, you have to let the amplifier cool off

for some time, and then switch it off and on using the

main power switch on the back panel.

2STANDBY

Press the standby button 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 illuminating the standby button. 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.

3UP BUTTON

The up button is used for switching inputs, and for

changing menu options, when in the menu. See ”MENU

FUNCTIONS” page 8.

4MENU BUTTON

The menu button is used for accessing the menu. See

”MENU FUNCTIONS” page 8.

5DOWN BUTTON

The down button is used for switching inputs, and for

changing menu options, when in the menu. See ”MENU

FUNCTIONS” page 8.

6MUTE / 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

8). The display will show ”Mute” instead of the volume

setting.

For remote pairing instructions, see page 7.

7VOLUME CONTROL

(ROTATING KNOB)

Use the rotating knob to change the volume or menu

settings.

REAR PANEL FUNCTIONS

8SPEAKER TERMINALS

The amplifier accepts speaker cables terminated with

spade connectors and 4mm 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.

9LINE 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 15dB 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.

10 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 head-

phone 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.

11 MAIN IN

Through a menu option, you can separate the pre- and

power amplifier sections of the I-880. When this

option is enabled, the “Main In” inputs are used as the

inputs of the power amplifier section. This can be used

in conjunction with the built-in crossover section, so

that the I-880 power amp section is used to amplifiy

only the high- or low frequency part of the signal, by

connecting cables from the “High Pass” or “Low Pass”

outputs to main in. The inputs can also be used with

external signal processors.

12 LOW PASS OUTPUTS

This set of outputs can be used, if you have a separate

power amp for the bass range, use the I-880 power

amp section for the bass range only or for driving an

active subwoofer.

13 HIGH PASS OUTPUTS

This set of outputs can be used, if you have a separate

power amp for the midrange/treble range, or if you use

the I-880 power amp section for the midrange/treble

range only.

14 RS-232, FIRMWARE UPDATE

The amplifier RS-232 terminal is used for firmware

updates. You can check for firmware updates on the

Aavik Acoustics homepage.

15 TRIGGER OUTPUTS

The amplifier is equipped with two DC trigger out-

puts. These can be used to power-on power amps,

sub-woofers and other equipment together with the

amplifier. When the amplifier is switched on (not in

standby mode), the trigger outputs will supply 12VDC.

They can supply up to 80mA total.

16 POWER ON/OFF SWITCH

Toggle the switch to switch between fully off and

standby mode. When the amplifier is in standby mode,

the power consumption is less than 1W. When the

amplifier is on and idling, the power consumption is

less than 150W.

17 POWER INLET (CAUTION!)

The amplifier accepts mains voltages from 100 to

240VAC 50-60Hz.

The power inlet accepts power cables with an IEC

60320-C13 female connector.

To ensure the best performance, please consult your

Aavik Acoustics dealer for a suitable mains cable.
