OPERATING YOUR MODEL 2100

FRONT PANEL CONTROLS

Power Button

A soft red glow surrounds the Power button when the Model 2100 is turned off. Push the

Power button once to turn on and the red glow will extinguish. When the Model 2100 is turned

on, the Input indicator and the selected input will illuminate green. The Mute LED will light up

during a 4–5 second delay after turn on. After the circuits stabilize the muting will disengage.

Push the Power button again to turn it off.

Note: The front panel Power button and remote control On and Off buttons are disabled when

the rear panel Auto Turn On switch is set to 12V or AC.

Sub Level Knob

The Sub Level control knob adjusts the subwoofer level. The sub level can be adjusted

between –10 and +10 dB, relative to the L and R channels. When the control knob is in the

12 o’clock position the sub level is boosted by 0 dB.

Bass and Treble Knobs

The Bass and Treble knobs adjust tone. Very slight tone adjustments can restore warmth, richness,

clarity and airiness that might be missing on certain recordings or because of room acoustics.

Larger tone adjustments will obscure musical detail, and even risk overloading your speakers.

Tone adjustments are audible only when the Tone indicator in the front panel display is lit.

Tone Button

Press the Tone button once to engage the bass and treble tone control circuits. Press a second

time to turn them off.

Tone is on when the Tone indicator in the front panel display is lit. The Tone button lets you

hear the difference between sound without tone adjustments (“ﬂat”) and sound with the tone

adjustments you made.

Note: You’ll hear the clearest sound when Tone is turned off and the audio signal path bypasses

the tone circuits.

Mute Button

Pressing the Mute button once will mute the signal at all of the Out jacks except the Record

Out. The red Mute light will ﬂash on the front panel while mute is engaged. Press the Mute

button a second time to cancel mute.

Input Knob

Rotating the Input selector will cycle through all 8 inputs. The front panel display indicates

which input is selected.

Balance Knob

Adjusting left and right channel balance is helpful to compensate for speaker placement,

room acoustics or if your power ampliﬁer’s gain isn’t identical for both channels.

Volume Knob

Your Model 2100 uses a high quality potentiometer to adjust the master volume level. Adjust

your power ampliﬁer gain controls (if it has them) so that your Model 2100 master volume knob’s

indicator is between 11 o’clock and 1 o’clock for your most typical listening level. This is its

“sweet spot” where the control’s left/right channel tracking is closest and its distortion is lowest.

Note: The Model 2100 has a gain of 12 dB, which is suitable for most brands of power

ampliﬁers and is an ideal match for all Parasound power ampliﬁers.
