The UMA™ 75TII and UMA™ 150TII are versatile mixer/amplifiers designed for numerous sound reinforcement applications. The flexible input configurations make these excellent choices for paging and/or back/foreground music systems. The UMA Series mixer/amplifiers are ready for any job, utilizing an isolated transformer with multiple output configurations.

FRONT PANEL FEATURES CHANNEL 1 LEVEL CONTROL (1)

Controls the signal level of the Channel 1 input.

CHANNEL 2 LEVEL CONTROL (2)

Controls the signal level of the Channel 2 input.

CHANNEL 3 LEVEL CONTROL (3)

Controls the signal level of the Channel 3 input.

CHANNEL 4 LEVEL CONTROL (4)

Controls the signal level of the Channel 4 input.

LOW EQ CONTROL (BASS) (5)

Active equalization control that adjusts the low frequency response. Clockwise rotation boosts lows while counterclockwise rotation provides a cut (reduction) of the low frequencies (±10 dB).

HIGH EQ CONTROL (TREBLE) (6)

Active equalization control that adjusts the high frequency response. Clockwise rotation boosts highs while counterclockwise rotation provides a cut (reduction) of the high frequencies (±10 dB).

CONTOUR SWITCH (7)

The "in" position of this switch provides 6 dB boost at 100 Hz and 10 kHz. The "out" position removes boost from the system.

MASTER (8)

Controls the overall volume level of the system.

POWER ON LED (9)

Indicates when AC power is being supplied to the unit.

SPS™ ACTIVE LED (10)

Illuminates when SPS™ circuitry is active. SPS™ eliminates power amplifier clipping.

ACTIVITY (SIGNAL PRESENT) LED (11)

Indicates signal presence at amplifier output. Illuminates when output is approximately 35 dB below full power.

CHANNEL 1 LED (12)

Indicates activity on Channel 1 mute line. Illuminates when signal is present on Channel 1 or when Mute 2 terminal is shorted to ground.

PAGE LED (13)

Indicates activity on Page mute line. Illuminates when signal is present on Page input or when Mute 1 terminal is shorted to ground.

POWER SWITCH (14)

Depress to "ON" position to turn on.

BACK PANEL FEATURES PAGE INPUT (15)

The Page input is a 600 ohm transformer balanced input. The telephone page input should be connected to the + and terminals; if a shielded cable is used, the shield should be connected to the

terminal and not connected at the source.

PAGE GAIN TRIM (16)

Controls the signal level of the Page input.

PAGE MUTE THRESHOLD (17)

Adjusts the level of incoming signal from Page input required to activate the muting of Channels 1 to 4. Clockwise rotation decreases the amount of signal required for muting. Full counterclockwise rotation will disable muting.

NOTE: Signal at Page input with appropriate Mute Threshold setting will mute Channels 1 to 4.

EXTERNAL REMOTE VOLUME (18)

These terminals allow connection of an external volume control. To gain complete control of volume from the external volume control, the front panel Master volume control must be set to maximum. The external volume control should be connected as shown in Figure 1.

CHANNEL 1 MUTE THRESHOLD (19)

Adjusts the level of incoming signal from Channel 1 required to activate the muting of Channels 2 to 4. Clockwise rotation decreases the amount of signal required for muting. Full counterclockwise rotation will disable muting.

NOTE: Signal at Channel 1 input with appropriate Mute Threshold setting will mute Channels 2 to 4.

CHANNELS 1 TO 4 SCREW TERMINAL INPUTS (20)

Channels 1 to 4 have low impedance mic and high impedance line level input capability. The low impedance mic input (

, Low Z +, Low Z -) is an electronically balanced input with built-in 24 V DC phantom power. The high impedance

line level input is a single-ended input. To use the High Z screw terminals, a jumper MUST be placed from High Z (-) to

CHANNEL 1 AND CHANNEL 2 XLR CONNECTORS (21)

These inputs are in parallel with the Low Z screw terminal inputs. Pin 2 on the XLR corresponds to the Low Z (+) screw terminal. Phantom power is supplied.

CHANNEL 3 AND CHANNEL 4 RCA INPUT JACKS (22)

These inputs are resistively summed to mono and are in parallel with the High Z screw terminal inputs. The shorting jumpers on the screw terminal inputs are shipped in place for these inputs.

MUTING SCREW TERMINALS (23)

Provides connection for external switch closure to activate muting functions. A switch closure from terminal 1 to mutes Channels 1 to 4. A switch closure from terminal 2 to mutes Channels 2 to 4.

24 V DC OUTPUT TERMINALS (24)

Provides connection for a low current (20 mA) 24 V DC output for powering low current external add-on equipment.
