1.Input Gain Controls

Sealed, conductive plastic rotary potentiometers.

2.Input Peak/Limiter LEDs

Dual-color LED illuminates red at 3 dB below clipping; illumi- nates amber to indicate limiter activity.

3.L-C-R Switches (Input Assignment)

Three-position switch assigns inputs to Left, Center (both left and right) or Right outputs.

4.Slate Microphone

Condenser microphone with AGC activated by momentary Slate Microphone Switches. Slate Microphone output ap- pears at all outputs.

5.Tone Oscillator/Slate Microphone Switch

Toggle switch activates 1 kHz tone oscillator when switched to the left position and activates the slate microphone when momentarily moved to the right position. Microphone inputs are muted when Tone Oscillator or Slate Microphone are activated.

6.Output Meters

Indicates peak output level in dBu.

7.Meter Brightness Control

Three-position switch adjusts the intensity of illumination of the output meter; low illumination, normal illumination, or super-bright illumination.

1.Mic Inputs

Transformer-balanced XLR inputs accept microphone level signals. Pin 2 = hot, Pin 3 = cold, Pin 1 = ground.

NOTE: You can use Shure A15LA line adapters to con- nect balanced, line-level sources to these inputs.

2.Phantom Power

Three-position switch selects either 48-Volt or 15-Volt phan- tom power for both inputs. Center position turns phantom power off.

8.Tape Return Switch

Toggle switch allows external audio to be monitored in the headphones. The center position is FP24 program audio. The left and right positions monitor tape return audio; the left position is locking, and the right position is momentary.

9.Headphone Connector

For stereo and mono headphones with ¼º connectors.

10.Headphone Volume Control

11.Headphone Peak LED

Illuminates 3 dB before clipping of either channel of the headphone circuit and either channel of Tape Return audio.

12.Power Switch

Three-position switch selects the power source. The unit is powered from internal batteries when in the left position; powered from external DC source when in the right position. Center position is off.

13.Power LED

Two-color LED illuminates green when the unit is powered and changes to red when batteries require changing. For external DC, the power LED is always green.

3.High Pass Filter Switch

Three-position switch selects 80 Hz or 160 Hz corner fre- quency filters, 6 dB per octave. Filters affect both inputs. Center position of switch removes filters from the signal path.

4.Tape Output

3.5 mm (1/8 in.) TRS stereo output (unbalanced) can be used to feed consumer level DAT, MiniDisc, and CD record- ers. Tip = Left, Ring = Right, Sleeve = Ground.

5.Tape Return Level Control

Recessed potentiometers adjust Tape Return level feeding the Headphone Monitor.

6.Limiter Switch

Activates input peak limiter. ON position functions as a dual mono limiter, with each input signal controlling its own limit- er. LINK functions as a stereo limiter, with both left and right inputs controlled simultaneously. Center position of switch turns limiters off.

7.Limiter Threshold Level Control

Recessed potentiometers adjust peak level of limiter activa- tion. Can be independently controlled for each input.
