Inputs

The K.2 Series ampliﬁer has three

separate inputs; two combination

XLR/1/4” Phone Jack (Inputs A and

B) and one 1/8” (3.5 mm) TRS jack

(Input C).

Refer to Figure 12

1. Input A

a. SIG LED – When illuminated

(green), it indicates a signal

is present. If this LED is not

illuminated, the input signal is

missing or too low to detect.

b. MIC LED – When illuminated

(yellow) it indicates the input

is conﬁgured to accept a

microphone input. When not

illuminated, it indicates the input is conﬁgured for a line-level input. You can change the setting through the Menu.

When MIC is selected, the MIC Pre-amp is activated, and the yellow MIC level LED illuminates. The MIC setting

should only be used if a microphone is connected directly to the MIC/LINE input. Note that the input does not

provide phantom power.

c. GAIN knob – Sets the sensitivity of Input A which controls the signal level sent to the ampliﬁer and the MIX OUT

(POST GAIN) output.

d. Combination XLR – 1/4” Phone Jack connector. Balanced XLR and 1/4” input. Accepts line-level or MIC-level

inputs. Select MIC or Line through the Menu.

CAUTION!: The MIC setting should only be used if a microphone is connected directly to the MIC/LINE input. Using the MIC

setting for line-level may introduce distortion. Use caution when changing to the MIC selection in the Menu as the output level

increases signiﬁcantly when MIC is selected.

2. Input B

a. GAIN knob – Sets the sensitivity of Input B which controls the signal level sent to the ampliﬁer and the MIX OUT

(POST GAIN) output.

b. SIG LED – When illuminated (green), it indicates a signal is present. If this LED is not illuminated, the input signal is

missing or too low to detect.

c. HI-Z LED – When illuminated (yellow) it indicates the input is conﬁgured to accept a high impedance input, typically

a musical instrument. When not illuminated, it indicates the input is conﬁgured for a line-level input. You can change

the setting through the Menu.

d. Combination XLR – 1/4” Phone Jack connector. Balanced XLR and 1/4” input. Accepts line-level and high

Impedance inputs. Select line level or high impedance through the Menu.

3. Input C

a. GAIN knob – Sets the sensitivity of Input B which controls the signal level sent to the ampliﬁer and the MIX OUT

(POST GAIN) output.

b. SIG LED – When illuminated (green), it indicates a signal is present. If this LED is not illuminated, the input signal is

missing or too low to detect.

c. Stereo 1/8” (3.5 mm) TRS connector – Accepts line-level stereo input. Stereo input received at Input C is summed

to mono.
