The lightning ash with arrowhead symbol, within an equilateral triangle,
is intended to alert the user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that may be of sufcient magnitude
to constitute a risk of electric shock to persons. The exclamation point
within an equilateral triangle is intended to alert the user to the presence
of important operating and maintenance instructions in the literature ac-
companying the device.

Rear Panel Features
1) AC Mains
This is the AC cord for connecting to 120VAC mains, 60Hz, 40W. Certain export models
connect to 230V and are labelled accordingly.
2) Main Speaker Outputs
This 5.08mm Euroblock connector is used for speaker output wiring. For low impedance
speaker loads , connect between the COM and 12V/4 Ω terminal or COM and 17V/8 Ω terminal. For
25V or 70V distributed speaker applications, connect the speakers between COM and 25V or 70V
terminals, depending on the transformers/speakers used. For distributed speaker loads on 230V
export models, connect between COM and 70V or 100V terminals.
3) CD/Satellite Input
These RCA inputs accept a stereo line level signal and sum them to mono on channel 3 input.
To use the CD/Satellite RCA inputs, be sure to set the channel 3 Select switch (#4 below) to the left.
4) Input Select Switch
This switch selects either the stereo line level input on RCA jacks, or mic level input on the
MIC 3 Euroblock connector.
5) MIC 3 Input
This 3.5mm Euroblock connector is used for MIC 3 input. To use the MIC 3 input, set the
channel 3 SELECT switch (#4 above) to the right. Wire the microphone (+) signal to pin 1, the (-)
signal to pin 2, and (G) to pin 3. If wiring an unbalanced mic input signal into a balanced Euroblock
input, be sure to ground the (-) input pin.
6) MIC 1 Input
This 3.5mm Euroblock connector is used for MIC 1 input. Wire the microphone (+) signal
to pin 1, the (-) signal to pin 2, and (G) to pin 3. If wiring an unbalanced mic input signal into a
balanced Euroblock input, be sure to ground the (-) input pin. MIC 1 input has ducking priority over
MIC 2 and MIC 3 inputs, with an adjustable ducking depth control. There is no phantom power
available on the TM-335.

7) MIC 1 Ducking Depth
This control adjusts the ducking depth of channels 2 and 3 when MIC 1 input has signal
present. Turning the control clockwise increases the amount of ducking.
8) Telephone Input
This 5.08mm Euroblock connector is used to connect with a 0.3V 600 Ω output from a tele-
phone paging system. Wire the telephone input (+) signal to pin 1, the (-) signal to pin 2, and (G)
to pin 3. If wiring an unbalanced signal into the balanced telephone input, be sure to ground the (-)
input pin. The telephone input has ducking priority over channels 2 and 3 along with MIC 1 input.
9) Telephone Input Gain
This adjusts the level of the Telephone input to the main output.
10) Telephone Input Ducking Depth
This control adjusts the ducking depth, or decrease in volume, of channels 2 and 3 when the
telephone input has signal present. Turning the control clockwise increases the amount of ducking.
11) Stereo Aux Input - 3.5mm Jack
This 3.5mm Tip Ring Sleeve (TRS) jack sums its left and right signals into mono, and overrides the
Euroblock Stereo Aux input when plugged in. To use this input, the select switch (#13) must be pushed left.
12) Stereo Aux Input - Euroblock
This Euroblock input connector sums its left and right signals into mono, and is overridden by
the 3.5mm stereo aux input. To use this input, the select switch (#13) must be pushed left.
13) Select Switch
This switch must be pushed left to use either the 3.5mm stereo aux input or the euroblock stereo
aux input. It must be pushed right to use MIC 2 input.
14) MIC 2 Input
This 3.5mm Euroblock connector is used for MIC 2 input. To use the MIC 2 input, push the
channel 2 Select switch (#13 above) to the right. Wire the microphone (+) signal to pin 1, the (-)
signal to pin 2, and (G) to pin 3. If wiring an unbalanced mic input signal into a balanced Euroblock
input, be sure to ground the (-) input pin.

Speaker Wiring
● Before connecting speakers to the TM-335 unit, be sure to disconnect the AC power cable.
● Make certain that the load impedance is not less than the rated impedance indicated.
● Low Z (4Ω or 8Ω), 25V, and 70V speaker loads should not be wired in combination with each other.
● Use class 2 wiring.
For the 4Ω low impedance terminal, connect as shown below, with the negative (-) speaker wire
connected to the COM terminal and the positive (+) speaker wire connected to the 4Ω terminal. Note
from the illustration how two 8Ω speakers can be wired in parallel to make a 4Ω load.
For the 8Ω low impedance terminal, connect as shown below, with the negative (-) speaker wire
connected to the COM terminal and the positive (+) speaker wire connected to the 8Ω terminal. Note
from the illustration how two 4Ω speakers can be wired in series, or two 16Ω speakers can be wired
in parallel to make an 8Ω load.
For 25V and 70V terminals, connect with matching transformers as shown below. Note: 230V
export models have 70V and 100V taps instead of 25V and 70V.

Typical Application
In this example, a dynamic microphone is connected to MIC 1, a stereo tv output is wired to
channel 2, and a CD player or satellite receiver is connected to channel 3 using the RCA inputs. A
telephone system paging output is connected to the telephone input. Signal present on either MIC 1
or on the telephone input will duck, or temporarily lower the volume, of both the TV and CD/Satel-
lite inputs. The amount of ducking is determined separately by the rear panel ducking depth controls
for telephone and MIC 1 inputs. Turning the ducking depth controls clockwise increases the amount
of ducking on channels 2 and 3 when that input is active.
Loudspeaker(s) are wired to either the 4Ω, 8Ω, 25V, or 70V output terminals. Make certain to
use only one type of speaker output, and to connect a total speaker impedance that is the same or
higher than the rated output impedance for the terminal used.
