REAR PANEL FUNCTIONS

SPEAKER 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.
9
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 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.
